This information was originally noted in the RASC Halifax Centre discussion List.
Just after midnight, I looked out our bedroom window to determine the status of cloud cover. Stars could be seen from the W-NW horizon all the way over to Saturn and Jupiter. Just had to go out to look for NEOWISE! Grabbed my clipboard and 10x42 image-stabilized binoculars to hopefully catch one last glimpse of the comet before it disappeared from our view.
NOTE: This comet had been discovered on March 27, 2020 and was an 18th-magnitude object located 2 AU from the Sun and 1.7 AU from the Earth. Its closest approach to Earth occurred on July 23, 2020, 01:09 UT, (3 days from now) at a distance of 0.69 AU while still in Ursa Major. It was 2nd-magnitude in mid-July.
Knowing where it had been in the previous two evenings, I began my search under the Big Dipper handle. Starting with Alcor-Mizar, I slowly made my way down towards the horizon, zigzagging short sweeps across the sky. It was about 20˚ above my horizon, nestled as it were between 57 Uma and 55 Uma on the right and slightly above the line formed by 61 Uma and HR 4536, HR 4452 and HD100235. The nucleus was very fuzzy compared to the clearly defined entity it was earlier in the week, and the tail was greatly diminished in size visually (perhaps 1˚-2˚ in length?). Location #6 now on my tracking star map for the comet!
It was 30 minutes very well spent looking at the comet and staring at the night sky to determine the star field around it. And then another 30 minutes re-sketching it with the appropriate labels for the stars observed and writing it up in my log book.
Response from Dr. Roy Bishop: Judy, there is no hope for you! Anyone who would write a report like that has been totally captured by the night sky. Normal people (99%+ of your fellow citizens) pay no heed to it. You should make an appointment with a psychiatrist.
To Dr. Roy Bishop from Dave Chapman: Anyone who has taken a peak at Judy's logbooks for Explore the Universe or Explore the Moon know that she is an Observer (with a capital O). Just don't mention Omicron2 Cygni around either of us....

Windless and no clouds.
The promise of a clear night was realized and Jerry was already taking time-lapse of the Comet. So, with clipboard, paper and pencils, red light to clip to the clipboard for seeing what I sketched (thanks, Melody), and my binoculars, I headed out to join him in our back yard.
First thing that came into view the moment I opened our back door was Orion, high in the sky above our tree line and its bright stars very evident in the dark skies. With Orion so high, I looked for the full Winter Circle - found! Turned about 45˚ to locate Cassiopeia, Ursa Major and Ursa Minor. The latter constellation was the one of primary interest given the comet wasn't too far away from Kochab. The only stars I could see in the Little Dipper were Pherkad, Kochab and Polaris (mag 2.0); with averted vision, I could see (imagined I saw?) Urodelus and Yildum in the handle and the other two stars of the dipper (Anwar al Farkadain, Alifa al Frakadain) - but they were very faint.
Using my 10x42 IS binoculars, I located Pherkad (mag 3.0) and Kochab (mag 2.0), noting 11 UMi (mag 5.0) next to Pherkad and HD133086 (mag 6.8) and TT UMi (mag 6.9) next to Kochab. With Kochab in my FOV, I had to go up just bit and to my right (east) to find it. A fuzzy cottontail, no tail with this equipment could be discerned. I then used my garden planting table as my easel to sketch it.

With Kochab in my FOV, I had to go up just bit and to my right (east) to find it. A fuzzy cottontail, no tail with this equipment could be discerned. I then used my garden planting table as my easel to sketch it. It was then that I turned my attention to other sights. First was the 5 stars of Cassiopeia above our greenhouse. I thought, "Perfect! I can easily find Andromeda." Wrong (and disappointing)! Andromeda was lower than thought and lost in the light pollution of our neighbour's backyard light that can be obscured by our shed and greenhouse if you stand in the right spot. |
|
Oh, well, Auriga is high and I can see it's bright 5 stars, especially Capella. Up with the binoculars to find the asterism Leaping Minnow. Several stars within Auriga comprise the asterism - 19 Air beside 18 Aur, 17 Aur beside IQ Aur, 16 Aur beside HD 34201, and 14 Aur. All in close proximity. Also close by and located with only a slight adjustment in declination of the binoculars were M38 (Starfish Cluster) and M36 (Pinwheel Cluster). Did not search for M37, nor did I sketch any of the objects just seen. I looked up again at Orion with binoculars to M42. I could see the nebulosity around its four stars but could not discern the two stars within θ1 Orionis and θ2 Orionis as I had January 11 using my 10" Meade SCT. |
I then turned 90˚ to the East to see Leo advancing high above the neighbour's roof. Denebola and Regulus as always stood out but I could also readily identify Zosma and Chertan in his hind end and the other "sickle" stars above Regulus (η Leo, Algieba, Adhafera, Ras Elased Borealis, Ras Elased Australis). I tried to find the galaxies below his belly but to no avail.
Getting late and fingers freezing, I called it a night. Hot chocolate, here I come!

Good Grief!
Observing in Less than Stellar Conditions
While enjoying my morning coffee on January 12, I read two articles in the February 2023 edition of Astronomy magazine – one by Bob Berman on page 12 made me chuckle and the second by Stephen James O’Meara on page 52 elicited an “ah-ha, so that’s what I saw!”
The curse of continuous cloudy skies disappeared on the previous evening, perhaps fleetingly, but nonetheless it was a clear, cloudless night. With my list of Messier objects to observe and to sketch, I stood beside our 10” Meade SCT that Jerry generously set up for me to view Cygnus’ brightest stars shining over western rooftops, Jupiter shining brightly in the south, and the Winter Circle with Mars and the Pleaides clearly visible in the east. At my disposal were 40 mm, 25 mm, 15 mm, and 10mm eyepieces and I was also going to try my Christmas gift - a Svbony 3mm - 8mm zoom eyepiece. My 10x42 image-stabilized binoculars were at the ready.
Bob Berman’s article explained how even backyard astronomers go through the five stages of grief when seeing is not the greatest. Seeing and transparency last evening were rated as average (and perceived as less than average); I experienced the stages just as he described. The session in question began at 6:45 PM AST and it wasn’t until I read his article that I could put it all into perspective.
Stage 1: Denial
Because I knew where to look, I found M31 using my 10x42 IS binoculars before beginning to look for M31, M32 and M110 with the Meade SCT. I used the go-to function and found the non-descript M31 smudge. There was no denying that M31’s characteristic features (bright centre, elliptical appearance) were being denied by the urban light dome, the sky conditions, the equipment used, or perhaps my watering eyes that required frequent drying. I could not make the stars in the FOV appear as pinpoints; they were fuzzy dots at best and mini donuts at worst throughout this session. I thought, “Okay, I know bad seeing is common so let’s look for another object. Maybe this was an exception.” Denial.
Stage 2: Anger
By changing an eyepiece or viewing the object again later in the session when sky conditions change, the possibility of observing the object in question usually improves – not this time. Again, the go-to function was used to “find” M110 (a small fuzzy). I was greatly disappointed in the lack of detail and the lack of definition of the stars, despite several attempts at focusing. Forget about finding M32 in that fuzzy non-entity. Andromeda, et.al., was a bust! The failure to observe these objects in the detail I wanted caused a bit of upset, anger to say the least. Adding to this, my headlamp’s battery died (special size of battery I didn’t have in stock), and I discovered my SQM’s battery was also dead. Bah, humbug.
Stage 3: Bargaining
In his article, Bob Berman stated, “You turn to the next stage: bargaining! Okay, but with whom?” A really good question given the sky gods seemingly weren’t cooperating so no sense appealing to them. I didn’t want to feel like I hadn’t tried, and Jerry was trying to help diagnose why I couldn’t “see” things. The decision was to bargain with myself. Bargain with myself? Who else was there? Try different targets, try different eyepieces, and keep my dry-eye syndrome at bay. My bargain was that if I succeeded in observing and sketching one target, I would go indoors to enjoy a hot chocolate.
Stage 4: Depression
How does one win a bargain with oneself? First, get gloves to keep fingers warmer (it was windless but -10 ̊ Celsius). Second, look for something the conditions would allow observing. Jupiter and its moons maybe? I started with the 40 mm eyepiece, then used the 25mm; Jerry could see the planet’s striping with both eyepieces albeit variable in moments of good seeing whereas it totally escaped me. This is the point where I considered giving up. What was the point in staying outside? Couldn’t see anything. Nothing worked. Bah, humbug.
I chuckled the next morning when reading Berman’s words: “...you suddenly realize what astronomers have known for 413 years: Wiggly, depression-inducing seeing is so widespread, you have no choice in the matter. A smile creeps across your face, the expression common to observers through the centuries. Finally you know its name and cause.”
|
Stage 5: Acceptance Having experienced this “success”, I slewed to view the Pleaides, saw Mars as a small red featureless spot centred in my FOV, and then turned my scope to Orion’s M42. I sketched what I saw, assuming it was M42 and other stars and nebula in close proximity. |
|
Now, let’s come back to my morning coffee and reading the February 2023 edition of Astronomy. Stephen James O’Meara, in his article entitled “The Theta Orionis challenge”, challenged us to split Theta1 Orionis and Theta2 Orionis without optical aids. It’s an interesting read but what especially caught my attention was the photo in his article. It was the mirror image of what I saw in my scope and what I had sketched! Ah-ha, so that’s what I saw! Four stars with one looking elongated (that I initially attributed to the frustrations experienced earlier), 3 bright-ish stars in a line with a fourth less bright forming an equilateral triangle with the two further out, and two stars (one above and one below the quadrilateral). The nebula surrounding it was heart shaped with the quadrilateral side more nebulous than the part covering the first star. |
Success!
What I learned from this session is that we as astronomers eventually do succeed when we keep going out into the dark and cold, despite all the grief it gives us while out there. We go back night after night (skies allowing) to observe that special object, to perchance sketch its details or to capture it digitally. It’s a process, one we go through alone or with like-minded others – and there’s always acceptance (at some level) of what we see and how well we see it. Don’t we all go through these stages at some point in our observing careers and doesn’t the memory of it stay with us – success or not?

No cloud, light breeze. Dew had already set in but hand warmers were applied to the scope and finder scope. Mosquitos to start the evening. Jackets not required for much of the evening. This was a session to hopefully overcome the alignment challenges experienced at Kejimkujik the weekend before (don't ask). Success with North level alignment, although it did require some minor slewing to centre the stars before saying 'yes, that's it'. I also had a new dual-circle reticule finder scope with which I practised 2-eye vision (just as Blair suggested years ago that I try).
The goals I set for this evening were to hopefully view some Messier and/or some of the DSOs in the now defunct constellation Taurus Poniatovii ("Poniatowski's Bull") - thanks, Dave, for showing me the Briaan Ventrudo article in Sky & Telescope (A Visit to Taurus Poniatovii). Success on both counts - not overwhelming success, but success nonetheless. I stayed out until 1:30 before taking down and after attempting to find a few other items in Taurus Poniatovii without siuccess. I would have been out a lot longer had we not been heading to the Valley tomorrow for a day at the beach.
Mizar (ζ Ursa Majoris) - Alcor (80 UMa) and HD116798 I then switched out the eyepiece for 15 mm and used that view to sketch what was seen. I could actually see Mizar's ζ1 Ursa Majoris and ζ2 Ursa Majoris separated, one slightly larger and consequently seemingly brighter than the other. Interesting that the jury is still out as to whether these are a visual double or whether they are in fact gravitationally bound. |

M13 (Hercules Globular Cluster) Using the 2-eyed vision through the finder scope, I had to slew to where I thought M13 was located a little below the line between η Herculis and ζ Herculis. Close. It was in the upper right quadrant of my 25 mm eyepiece FOV. There was a bright star above it, a semi-circle of stars in the left FOV, and a triangle of stars to its upper right where one star was either a double or just had an optical double. After sketching the 25 mm view, I inserted my 9.7 eyepiece for a completely different view. I could see the core was quite dense and there was a lighter area around its perimeter. There was a crescent of stars adjacent to it that I could not identify and a bright star in the upper right quadrant (maybe HD 150998). |

Scutum was high in the SE sky so easily located tonight. M11 is one of my favourite clusters. It is easy to locate visually and with binoculars and can be easily identified in a time-lapse photograph. I consider it the golf ball that is next to the golf club.
I was learning to slew this new-to-me telescope. I slewed SE from β Sct where the cluster appears. It had one bright focal point but with averted vision there was a hint of many stars in the nebulosity. There were 2 stars (SAO 142703 & V369 Sct) that were close to the cluster and appeared to have some nebulosity as well.

M14 appeared as a faint fuzzy half way and east of the line between Celabrai and Sabik. I could not make out any individual stars but it was equally 'dense' within the cluster.
There was an arc (like the one in Scorpius that includes Graffias). It was to the NW along with a much brighter star in the west. Two there stars appeared in the FOV as well.

As is my habit, I look out my window every evening after lights out. In the west was a bright seemingly twinkling reddish object. Was it a plane or a star? I stared at for a good 30 seconds to determine if it appeared to be getting closer or if it was it blinking, then gave up - got out the binoculars in the bag at my feet.
Yup. A star. A bright one with a group of stars in the same FOV completing the formation of a U". But what star had this star field? Now to SkySafariPro for some assistance. Arcturus! Positively identified with the U-shaped star field. Arcturus was very bright and large compared to the dimmer, smaller stars of the star field.

M12 was found by slewing from M10, eastwards and up slightly. What I found interesting when using the 5 mm eyepiece was the bright two stars in the lower right quadrant of the cluster's nebulosity. I couldn't make out any other stars in the cluster.
There was an arc of stars to the east of M12 and 2 others at a diagonal (NE-SW) west of M12. Several other very faint stars were visible with averted vision but there were too many to sketch.

Learning to slew this new-to-me telescope to the object, and thankfully Ophiuchus remained high in the sky for this session. I have viewed M10 numerous times with 10x42 IS binoculars so knew generally where to look along the line (1/3 of the way up) from Sabik to κ Oph.
It was a very faint roundish object. I could not see any individual or bright grouping of stars within the cluster.

This was the first time using my new-to-me go-to EVOSTAR 80 ED on a brand new AZ-GTI mount on its tripod. It was quite steady. Jerry and I were 'playing' with the star alignment options before delving into observing.
Mizar + Alcor + HD 116798 Once again, I looked for the double stars Mizar and Alcor to also find their 3rd smaller and dimmer companion HD 116798. The eyepiece also allowed for a splitting of Mizar into Mizar A and Mizar B. Very happy about that. There was another star almost due west of Mizar - GAIA 1563592744010133120 ("GAIA" in the sketch). |

Albireo Albireo β1 was a very bright yellow and was quite close to the blue Albireo β2. I also noticed 3 stars south of Albireo and one slightly above at 2 o'clock that formed an arc. There was also a very bright one at 10 o'clock. |

One exciting rediscovery for me was the Aristarchus Plateau that was just above the line of the terminator. Around 7:30-8:00 PM, the rims of the two craters (bright-walled, central peaked Aristarchus and flat, dark-floored Herodotus) were very bright and that was what captured my attention at first. I initially thought they were Kepler and Encke until I used Sinus Iridum and Mare Imbrium to get the correct orientation of the Moon and therefore correctly determine what it was I was looking at. The curved Vallis Schröteri with its little kink halfway along the bend joined to Herodotus was seen with a pin-thin shadow on its floor. I could not discern the cobra head at the valley terminus near Herodotus.
I had seen the Plateau, associated craters, and the adjacent Montes Agricola before when it was well away from the terminus. Refer to IWLOP #122 - Aristarchus Plateau and Plateau Schröteri for details of my first observation of this interesting area.

Day 1 (June 27): We arrived on a warm sunny day with light to moderate winds across Kejimkujik Lake - until we turned towards our site on Big Muise Island. The wind had certainly picked up and continued to increase over the afternoon and evening. Rain!! Most of the afternoon into the evening, heavy bouts throughout the night. Observing out of the question!
The Kejimkujik observing gods were with us for night 2 at this idyllic location.
|
Dave referred to distractions that seemingly prolonged our observing session. One was my so-called "little binoculars" - 2.1 x 42, FOV 26º. Dave, Jerry and I had fun sharing them throughout the session and we chuckled with each handover because eyepiece adjustments had to be made each time.
Mother Nature also gave us reason to pause throughout the night. We saw an owl, perhaps the Barred Owl we saw earlier, swoop silently to the reeds on our shore, hover, then silently fly to the opposite island. Fireflies in the shrubbery were a lighting surprise. Peepers and bullfrogs croaked occasionally. The anticipated soulful call of loons interrupted the quiet of the Kejimkujik night at least 3 times, beginning at sunset and continuing well into the night.

|

M17, M18, M24 + Dyer's Top 10, #3 In addition, I used the length of Kaus Australis to Kaus Media and went up x3 that length in binoculars to locate the small open cluster M18/NGC 6613 and M17 (Omega Nebula) above it with its larger size and nebulosity. |
|||
Ophiuchus, M10/NGC 6254, M12/6218 + Ophiuchus is never hard to find above Scorpius and adjacent to Hercules. Its main stars were easily located from Rasalhague down to Sabik. I knew that two Messier objects were in the interior lower 1/3 of the constellation. I visually located Marfik/λ Oph, put my binoculars up and looked east of there to find both M10 and M12 well within my FOV. Both appeared as small greyish fuzzy objects. Dyer's #1 Dyer's #5 |

Scorpius + NGC 6231 + Collinder 316 - New to me! Using binoculars, I noticed 3 very bright stars I thought were below Scorpius. Turns out they were actually in the tail - ζ1 Sco, ζ2 Sco and HR 6266. In the same FOV and above them was a beautiful little cluster with quite a bright core that I identified as NGC 6231; not really sure if I could make out any individual stars. Looking above NGC 6231 was a scattering of stars with about 9 bright stars among thousands less bright distributed throughout a broad nebulosity - Collinder 316 - and it was quite a large open cluster! Come to find out when I returned home that NGC 6231 was observed in San Pedro de Atacama (2018) when shown the "false comet" that was formed by it and Trumpler 24. As long as these features remained above the horizon, I kept returning to look at them. Beautiful. An 'oh wow' moment on the beach that I wanted to etch into memory. |
|
||
Keystone of Hercules + M13 (Hercules Globular Cluster) With such a clear sky, I sought the Keystone of Hercules to locate M13 (Hercules Globular Cluster). Looked for the Big Dipper, moved easterly to Corona Borealis then further east for the Keystone quite high in the sky. With binoculars, I looked 2/3 of the way north from ζ Herculis to η Herculis. Success! There was the familiar small grey fuzzy. |
|||
Scutum Star Cloud (Dyer's #4) Scutum Star Cloud is one of my favourite sites to find as it contains M11 (Wild Duck Cluster). Always able to find this object because of its rather square-ish nebulous appearance with a bright object in each of the uppermost 2 "corners" (M11 and β Sct). In my binocs, M11 looks like a small, bright, round fuzzy golf ball beside the golf club formed by stars in the star cloud. |
|||
M55 / NGC 6809 (Summer Rose Star) M55 is located between the Teapot in Sagittarius and Capricornus. I used the Teapot as the start point to find it, placing Nunki at about 2 o'clock in the FOV. I then moved down 1 FOV where the globular cluster was just off-centre. It can also be found by going from Ascella to τ Sgr in the lower handle of the Teapot then following the arch of stars from there - ψ Sgr to ξ Sgr to 52 Sgr. The cluster can then be seen "below" 52 Sgr. |
|
||
Delphinus, Equuleus, Sagitta + Dyer's #7 Dyer's #7, the Coathanger / Collinder 399 / Brocchi's Cluster, is one of my favourite asterisms to view in the night skies. Easily found 1/3-1/2 of the line from Albireo (in Cygnus) and Altair (in Aquila). In our Northern Hemisphere, the hanger is upside-down and at an angle. All 10 stars in this asterism were easily seen and identified. While in the Coathanger neighbourhood, I visually located three familiar friends:
|
|
||
M53 / NGC 5024 I used Arcturus as the start point, then travelled down to Muphrid. From there, I went 1.5 FOVs and M53 was pretty much centred in my view above Diadem (α Comae Berenices). It was small, dense, faint grey, and circular. |
|||
M3 / NGC 5272 I used Arcturus at the 8 o'clock position in my FOV then moved up 1 FOV. M3 was then seen. There appeared to be distinct formations formed by stars adjacent to M3 that I attempted to identify. Not sure if these are correct.
|
|
||
Dyer's #8, #9 & #10 Certainly, some objects on his list were new to me and did provide fun and a challenge to find and observe, such as nebulas with 10x42 binocs. It was around this time we heard the bullfrog for the first time and noticed fireflies in the shrubbery between us and the campsite. Dyer's #8 - New to me! Dyer's #9 Dyer's #10 - New to me! |

Leaping Minnow / Flying Minnow (Asterism) It includes Aurigae 14, 16 & HD 34257, 17 & IQ Aur, 18 & 19 and another star unidentified. It doesn't look like a minnow in the star maps but it sure does in binoculars! Can't miss it! If looking in a telescope it is between IC410 and the Flaming Star Nebula / IC405. |
Geminid Meteor Shower

Jerry and I were in our back yard. He had set up his camera to capture some Messier objects, whereas I had set up the 10" Meade (with his help). According to Astrospheric, the skies were average Seeing and below average transparency. Bright stars were clearly visible but I did recognize that dimmer stars would be more challenging to see.
This evening's session had 2 purposes:
1- To use my new acquired 20 mm illuminated reticule eyepiece, and
2- To practise conducting what I refer to as the 6-star alignment but was actually a 2-star alignment plus 4-star calibration. The stars used for the alignment were Spica (in Virgo) and Dubhe (in Ursa Major). The calibration stars used (not in order they were used) were Mizar (in Ursa Major), Denebola (in Leo), Arcturus (in Boötes), and Alphecca (in Corona Borealis). It wanted to use Vega and we did let it slew to its location but we would have to move our house for it see it. Too funny.
After finding each of the 6 stars using the go-to feature of the telescope, I centred the object in the finder scope then went to the eyepiece to centre it using the lit reticule. What a difference it made with the object truly centred. Changing to an eyepiece with a higher smaller resolution would mean the object would remain in the FOV which would allow for sketching of the objects and the star field (perhaps at different magnifications). With each star being centred and confirmed, the ability of the scope to find have the wanted object in the FOV improved.
Castor |
This was an "Oh, Wow!" moment. I had Castor centred in the illuminated reticule, turned off the light and noted the star appeared elongated, perhaps due to not being in focus. When focused, there it was - a double star! Oh, wow! Two stars, one above the other, one brighter than the other, one larger than the other and extremely close to one another. I could also see two other stars in the FOV that otherwise was devoid of any other stars. Using SkySafariPro, I was able to identify the two stars as YY Geminorum (also known as Castor C) and TYC2453-0454-1. |
When I went back in the house later, I did some research on Castor. SkySafariPro had named both stars as Castor α Gem with no distinction other than different magnitudes. This piqued my curiosity. Come to find out that Castor is a 6-star system, all of which are spectroscopic binaries. Castor A and Castor B have magnitudes of 1.9 and 3.0 respectively and only 6 arc seconds apart. Castor C is an eclipsing binary with an apparent magnitude of 9.8; it is 73 arcseconds distant from the bright components.
All six stars are bound to each other by gravity and share a common motion through space. The components of each of the three binary systems orbit each other and the three binary pairs also circle around each other in a total of five orbits. Castor A and Castor B have a period of 445 years and Castor AB and Castor C complete an orbit every 14,000 years. Individual components have much shorter orbital periods: 9.2128 days for Castor Aa and Castor Ab, 2.9283 days for Castor Ba and Castor Bb, and only 0.814 days for Castor Ca and Castor Cb.
M105

Instrument: 10" Meade SCT with 20 mm, 15 mm, 12 mm with 90º FOV
Magnification: x125, x167, x208
SQM: 19.52
Using SkySafariPro, I located M105 halfway below the imaginary line joining Regulus to Chertan. I then used the go-to to slew to that area and saw after much staring in to grey space what was a very, very faint smudge that I centred in the finder scope. I then moved to the SCT and had to make minor adjustments to get the smudge centred in my newly acquired 20 mm lit reticule. No definitive shape other than potentially an oblong out of focus. It remained as an undefined grey smudge on a grey starless star field despite several attempts to see it using the 20 mm, 15 mm and 12 mm. I gave up for the evening, especially in light of the poor quality of the transparency. So disappointing.
Perhaps next time I should try one of the many filters I have to determine if one of them makes a difference in what is seen.

Constellation: Ursa Major The Big Dipper was standing on its handle above the roofline of our house in the NE. This was my first observation of the double star in Ursa Major! I used the telescope to find Dubhe from where I was observing M35 in Gemini. I then slewed to Merge before going a little lower on the right. The pair become very evident in the FOV. The stars comprising the pleasingly close pair were: These 2 stars were amazingly bright against the "black background." |

Constellation: Auriga It's a very open but faint and diffuse cluster. I could see how it got its name while looking through the eyepiece (with a bit of imagination) but it did look more like a cross. I don't think my sketch captured the starfish appearance. To my eyes, it looked like a cross on its side. I had slewed northerly of M36 to find M38. |
NOTE:
I had observed M38 almost 4 years ago at SCO - a night of discovery!
Date: 2018-05-18 Having found M36 a few moments ago, I moved my binocs just a little towards the north (~ 1 FOV). M38 was very faint in the binoculars so tried the SCT - success! Still a bit faint and diffuse in the eyepiece but I could see 4 definitive bright stars. There rest of the star field was diffuse; perhaps because of the haziness closer to the horizon, the "cross" structure I had read about wasn't visible. |

Constellation: Auriga I was visually observing Messier objects and Jerry was imaging DSOs. I slewed the scope "up" from Elnath in Auriga, just west of the line formed between Elnath and θ Auriga. I had used the same technique in a 2018 observation. M37 was seen as a very open cluster. Couldn't determine a pattern or shape other than the curve of stairs in the SE. |
NOTE: I had observed M37 for the first time four years ago, and have looked at it with binoculars many times since.
Date: 2018-05-18 Now that I knew M37 is an open cluster (not a globular one as I had assumed 4 nights before), I hoped to have a better chance of finding it just west of the line formed between Elnath and θ Auriga. It was very loose with a bright central star and 5 other bright stars. The haziness near the horizon made for difficulty in seeing more stars of the cluster. I used my binoculars and after a few tries I found it! I drew it as I saw it. Jerry then used our SCT* to confirm it was what I saw.
* At this time, the SCT was not on motorized mount. We jokingly referred to it as the "push-to SCT." |

Constellation: Auriga I knew M36 was between M38 and M37. After locating M37, I slewed the telescope northerly and a little lower towards the horizon. The centre seemed to be filled with multitudes of dim stars. No one star really stood out as being the brightest in the cluster. Could see where some of the lines of stars were curved like a pinwheel's blade, although one may not guess that from my sketch. |
NOTE:
I first viewed this Messier object almost 3 years ago.

Constellation: Gemini Jerry and I were looking for Messier objects - me to visually observe (outside), him to image (mostly inside). Gemini held its high position above our trees to the W-SW. Located Tejat then slewed northerly and lower towards the horizon just a little. It's a beautiful cluster with lots of stars. I began my sketch with the two bright central stars. There was a curved line of 5 stars to the east of them. Seven stars that went SW then 2 stars to the west looked like a hockey stick with a super huge blade. Didn’t notice nor look for the adjacent NGC 2158. |
NOTE #1: I first viewed this cluster on May 5, 2018 at 10:10 PM at SCO with binoculars. It looked like a fuzzy circle when viewed with averted vision. I could detect 4 bright stars.
NOTE #2: Had another look on April 2, 2022 where I may have also seen NGC 2158 nearby.

Constellation: Cassiopeia Tried 40 mm Plössl but the cluster was too small and faint so switched to the 25 mm Plössl. I used the distance from Shedar to Caph, followed the line they formed up the same distance to find M52. Had fun trying to slew at an angle versus a vertical or horizontal line. M52 is much smaller and fainter than the 3 Messier objects in Auriga. Looked almost rectangular in shape with the brighter stars on the north side. |
IWLOP #102 - Mare Cognitum & Kuiper
Mare Cognitum, the “Known Sea,” was named in 1964 to mark the successful flight of the Ranger 7 spacecraft, which sent back the first detailed television pictures of the lunar surface. Kuiper, located in central Cognitum, is an excellent example of a small, simple crater.
Location: 9.8 S 22.7 W Origin: Impact Size: 6.8 km (Kuiper) Rukl: 42 Type: Simple Crater (CS)
Objects: Mare Cognitum, Ranger 7 landing site, Kuiper, Darney, Mons Moro

R1: Mare Cognitum is between Oceanus Procellarum in the northwest, Mare Nubium in the southeast, and Mare Humorum in the southwest. The Ranger 7 landed southeast of Kuiper.
R2: Kuiper is in the centre of the mare in what appears to be a flat plains. Darney is located in a rugged mountainous area south of Kuiper and appears to be about twice the size of Kuiper.
C1: There are several wrinkle ridges throughout the Mare.

C2: Mons Moro appeared as a small raised area or mountain (?) SW of Kuiper and NW of Darney on Mare Cognitum. Couldn't make out any distinctive features.
NOTE: (July 15, 2021) Investigated to confirm my findings last year regarding size and found that Darney's width is 15 km which is a little more than twice the size of Kuiper. Good guess on my part.
IWLOP #101 - Kies, Mercator & Campanus
Kies is a flooded crater with a nearby volcanic dome designated π (Pi). Mercator and Campanus are two nearly equal-sized craters located at the edge of Mare Nubium.
Location: 26.3 S 22.5 W Origin: Impact Size: 44 km (Kies), 47 km (Mercator), 48 km (Campanus)

R1: Directly south of Bullialdus is Kies. It's walls are barely seen; the SW has a small area that is quite high. It's shaped like a small magnifying glass, short handle that may be higher in elevation than the crater walls. |
C1: The volcanic dome just west of Kies designed π was observed; it appeared as a slightly raised area.
C2: Mercator does not have a peak whereas Campanus does. Campanus has a peak, its floor is darker and its sides steeper than those of Mercator. The unnamed rille appears as a thin dark line between the two craters; the south section curves into an area between the craters then heads north towards the small mountains on the mare floor.
IWLOP #114 - Mons Delisle & Mons Vinogradov

There was cloud cover from 11:40 PM to 11:55 PM. Knew where to look once clouds opened for viewing.
R1: Delisle is a little deeper than Diophantus; both are round but couldn't see either floor. Mons Delisle appears as a partial semi-circle, almost tooth-shaped with the point well lit and the base darker. Mons is steep-sided on the inner curve. |
R2: Diophantus shallower than Delisle, has a central peak with a ridged west wall. Mons Vinogradov shows 2 bright areas in the SE. The whole area looks triangular in shape with the 2 bright spots on one of its sides. Also, several domes (approximately 12) were seen east of the Mons. |
IWLOP #117 - Mons Gruithuisen Gamma (ϒ) & Delta (δ)
Impressive twin-shield volcanoes on boundary between Mare Imbrium and Oceanus Procellarum.
Location: 36.3 N 40.0 W Origin: Volcanic Size: 20 km each Rukl: 9 Type: Domes

R1: The two domes stood out as bright, white entities like sentries standing guard at the entry to some highlands/craters. Delta wasn't as bright as Gamma but Gamma was tall enough to cast a shadow on Delta. Delta appeared elongated compared to the rounded Gamma. Tall shadows created by both. The crater Gruithuisen appears round with a bright rim. Upon closer examination, I realized a small crater had impacted the rim, giving me the false initial impression of a deteriorated wall.
|
C1: Could not see the summit crater on Mons Gruithuisen Gamma.
C2: Most of Mairan was in shadow. Mairan T was beyond the terminator.
IWLOP #105 - Montes Carpatus

R1: Montes Carpatus extends east from Gay-Lussac to T. Mayer in the west. It appears to have been impacted numerous times or was created when Mare Imbrium was first impacted. Irregular peaks and valleys along its length. C1: The herringbone pattern of secondary craters begin above Copernicus and continue to the east half way along the range on what appears to be both sides. |
IWLOP #111 - Hortensius & Hortensius Domes
A fine sharp-rimmed crater (2860m deep) with a fascinating group of domes nearby. The domes are quite obvious under the right lighting conditions, but are elusive at other times.

R1: Located Hommel SSW of Janssen. Identified its craters A, B, C, D, H and P. Also located J, Q, R, S, and V. NOTE: It was difficult to discern exactly where this crater's walls were located given the numerous impacts it had on or near its original walls. Took a photo at the telescope of what I was viewing then used Rukl to help determine what I was seeing. |
R2: Pitiscus had an off-centre crater next to a raised formation; there was a terraced SW wall with a crater. Vlacq appears to have sharp edges and perhaps 2 peaks or a split central peak. Rosenberger is shallower and its SW rim appears worn. |
|
C1: Biela is an oval with crater C impacting its NE rim; crater A is just above crater C. Nearch and its crater A were also identified. Hagecius has large craters B and C on its SE walls. |
IWLOP #025 – Mare Nectaris ("Sea of Nectar")
The smallest of the major circular maria at 350 km across, it formed about 3.92 billion years ago. Even though Mare Nectaris is relatively small compared to other large basins, it still covers over 10 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below. The absence of rilles may relate tot he relative thinness of lava in this mare.

R1: Wrinkle ridges on eastern areas of Mare Nectaris and west of Bohnenberger are almost parallel to Montes Pyrenaeus. Arcurate rilles not evidenced.
C1: Bohnenberger is west of the lower half of the Montes Pyrenaeus. Rosse is slightly off-centre of the Mare and it appears that its ejecta runs north-south with some going eastward. Beaumont (west of Fracastorius) looks to have its northern rim eroded; couldn't see features on its floor.
C2: Daguerre at this point in the lunation appeared almost as a ghost crater. However, the ejecta ray from Mädler goes through one of the craters just inside Daguerre's eastern rim, and that helped identify Daguerre's location.
IWLOP #032 – Wohler
Slightly elongated intermediate crater with a smooth floor.

R1: Wohler has no central peak; its SW wall is wider and steeper than the NE wall. Not as deep as Stiborius. Stiborius has a central peak and appears to be in a relatively flat area (of another crater?). The SW wall is particularly steep, and wide walls in the SW. Stiborius C much shallower and smaller.
C1: Nicolai looked circular with 2 craters on its north wall and had a flat floor. Nicolai A also noted. Spallanzani looked to have a small crater on its west wall and was much smaller than Nicolai. Because Spallanzani was close to the terminator, I couldn't see its floor or interior rim details.
C2: Numerous craters were seen in this area - craters upon craters.
IWLOP #046 - Zagut, Rabbi Levi & Lindenau

R1: Zagut had the large central Zagut A on its floor and Zagut E on its east wall. Rabbi Levi had 5 craters in its western floor plus numerous others on its eastern wall. Lindenau had 2 peaks split by a rille; its western wall appeared terraced/slumped almost to the peaks. | |
R2: The circular Rothman was located northeast of the trio craters and had a central peak plus steep walls. Celsius was west of the three, forming a triangle with Zagut and Rabbi Levi. Besides the north crater on its floor, there appeared to be other structures such as rilles on its north floor. Every wall of Celsius appears to have small craters. |

Mostly cloudy with large sucker holes that eventually cleared off completely. Got to see Newcomb once more and its related craters, A, B, C, G, and J. Craters J and G were in line with A. Crater G looked to be the shallowest and to be the most elongated. B and C were identified to the NE of this line of craters. Could very easily see the clump on one end of the crater and where Crater A had impacted its NW rim. Montes Taurus was seen as well to its SW.

R1: Bohnenberger was on the west side of Montes Pyranaeus; small craters to the north and south. A north crater and Bohnenberger appear to form the exterior walls of a valley. Half way up , there is an east-west break the mountain range. There's a jagged ridge on the the N side of the valley - both sides of the valley, actually. The valley looks to be crossed with 2 ridges.
The Montes Pyrenaeus appears short with interruptions, but its western edge appears to be continuous from Bognenberger to Gutenberg.
IWLOP #016 – Franklin & Cepheus
Fine duo of craters located to the northeast of Lacus Somniorum.
Location: 38.8 N 47.7 E Origin: Impact Size: 56 km, 40 km Rukl: 15 Type: Simple Crater (SC)
Objects: Franklin, Cepheus, Cepheus A
Others Identified: Atlas, Berzelius, Hercules, Oersted, Posidonius
Location: Home
Date: 2021-05-15
Time: 8:50 PM ADT
Equipment: 10" Meade SCT, 4.7 mm
Magnification: x530
Transparency: Very Good (4)
Seeing: Excellent (5)
R1: Franklin: Central peak, well terraced crater walls. Appeared to have one area of its wall that wasn't as clearly defined as the rest; perhaps due to lighting or my perception of reality.
R2: Cepheus: Smaller than Franklin and to its NW. Crater A impacted the eastern wall and is quite deep.
NOTE: These craters are in a SW line from Atlas. Franklin had a ghost crater to its SE.
IWLOP #020 – Metius & Fabricus
These two prominent craters are nearly equal in size and structure with deep walls.
Location: 40.3 S 43.3 E Origin: Impact Size: 88 km, 78 km Rukl: 68 Type: Simple crater (CS)
Objects: Metius, Metius B, Fabricus, Brenner, Brenner A
Others Identified: Brenner E, Janssen, Lockyer, Steinheil, Vallis Rheita, Watt
Observation 1: R1: Metius B was located on the NE floor of Metius. Fabricus had me questioning why there was a darkness on the floor, like a large rille or rima encircling 3 of the 4 sides of the floor. C1: Brennar looks like a small flame or leaf. Brennar A impacted on its SE rim and could also see E on its NE rim. |
Observation 2: Had a much clearer view of Fabricus. NOTE: Discovered in Rukl 68 there are 2 central ridges that create shadows on 2 sides of the crater. The 3rd side is steep near the crater floor and casts another portion of dark shadow. With this magnification, there was clearer definition of the rises on the crater floor as shown in Rukl. |
IWLOP #011 – Cleomedes & Macrobius
Prominent eroded craters to the west of Mare Crisium.
Location: 27.7 N 55.5 E Origin: Impact Size: 126 km. Rukl: 26 Type: Complex Crater (CC)
Objects: Cleomedes, Cleomedes B & J, Cleomedes E & A, Delmotte, Tralles, Debes, Rima Cleomedes, Macrobius, Macrobius C

R2: The SW wall of Macrobius was particularly terraced. Central peak looked a little off-centre. C3: Crater Macrobius C looked to have been created on the SW rim edge (refer to sketch). The crater rim was seemingly quite sharp where the crater was formed. |
IWLOP #017 – Steinheil & Watt
Two nearly equal-sized craters sharing one wall.
Location: 48.6 S 46.5 E Origin: Impact Size: 67 km, 66 km Rukl: 76, 68 Type: Simple Crater (SC)
Objects: Steinheil, Watt, Mallett J

Magnification: x530
Seeing: Excellent (5)
Transparency: Very Good (4)
R1: Steinheil had a smooth floor and is superimposed on Watt and has slight ridging to the walls. I could see where there was a thickened, terraced wall where Watt was impacted by Steinheil. Watt also had creases on its floor.
C1: Mallet J can be seen on the opposite side of the Vallis Rheita from Mallett.
Note: Both craters appeared oblong but this may be due to closeness to the SE rim.
IWLOP #019 – Newcomb
Named for noted Canadian astronomer Simon Newcomb, whose name is also honoured the RASC's Simon Newcomb Award.
Location: 29.9 N 43.8 E Origin: Impact Size: 39 km Rukl: 25 Type: Intermediate Crater (CI)

Found Newcomb! This also happened to be the last object to observe for the RASC Observe the Moon (telescope version) certificate for which I had completed all 100 objects plus the optional items for that program.
R1: There was a plateau or bay similar in shape to Fracastorius. I looked for this bay SW of Geminus.
NOTE: Could also identify craters B & C adjacent to J & G.
IWLOP #034 – Dorsa Aldrovandi & Mons Argaeus
Note darkened area of Mare Serenitatis in this vicinity, especially when the sun is high.

Observation 1:
Time: 9:00 PM – 9:50 PM

SQM: 18.56
Equipment: 6” Dobsonian, 9.7 mm + 15 mm eyepieces
Magnification: x124 + x80
Transparency: not recorded
Seeing: not recorded
Quite excited when my Moon app showed that Newcomb - the last object to be viewed - could potentially be seen. Quickly set up the Dob and inserted the 9.7 mm eyepiece. The image as not only backwards but also upside-down. How confusing!
Once I had it figured out, I recognized Cleomedes, Burckhardt and Geminus as the 3 large craters “below” (in reality it was above) Crisium. Macrobius was located on the west side of Crisium. I then identified Lacus Bonitatis; there appeared to be a bay or plateau “below” it and Newcomb was beside this not too far from the terminator. Consequently, did not get a good view of the crater. Perhaps I need to wait a while and try again?
Observation 2:
Time: 11:05 PM – 12:00 AM
Equipment: 10” Meade SCT, 9.7 mm + 15 mm + 4.7 eyepieces
Magnification: x258 + x167 + x532
Transparency: not recorded
Seeing: not recorded
Moon was getting quite low and there was light cloud cover occasionally. I tried all three eyepieces; the 4.7 mm was too zoomed in and difficult to focus at x532 magnification. However, even though it was almost 2 hours later, I was unable to get the detail of the crater itself. Therefore, no sketch. Looking at Rukl 25 and comparing it to the view I had in the telescope and later in the very fuzzy photo I took with my iPhone, I could identify A, B, C, J and G beside it but could not describe any details. Montes Taurus was seen briefly as they were on the terminus. Lesson learned – take out the big scope first!

IWLOP #122 – Aristarchus Plateau & Vallis Schröteri
Aristarchus is a bright, complex crater that is a little older than Tycho, and is located near the edge of a unique plateau that rises 2 km over Oceanus Procellarum. Vallis Schröteri was a lava tunnel that carried lava from the highland plateau to the adjacent basin.
Location: 23.7 N 47.7 W Origin: Impact and Tectonic Size: 40 km (Aristarchus), 230 km diameter Rukl: 18 Type: Complex Crater (CC) and Valley

R1: Aristarchus was quite bright. Bright rays of ejecta to the south and west. The diamond-shaped plateau was darker than the surrounding Oceanus Procellarum. Ejecta may have gone as far as Montes Carpatus and meets those of Kepler in the south.
R2: Vallis Schröteri starts on Oceanus Procellarum, meanders N, then NW, then South. The rille ends in a cobra head north of Herodotus.
R3: Montes Agricola well lit on the eastern slopes. It formed a border of the diamond plateau.
C1: The 3 rilles not observed at this time.
C2: Saw the cobra head NE of Herodotus.
C3: Mons Herodotus was a singular bright spot between the Vallis and Montes Agricola. Two other bright "spots" to the North but too far to be related (?).
This was my first observing of this feature. It seen again on July 10, 2022 with our youngest granddaughter.

IWLOP #115 - Kepler & Encke
Recent impact crater Kepler (32 km), with its uneven floor and bright ray system, contrasts with older crater Enke of nearly the same size.
Location: 8.1 N 38.0 W Origin: Impact Diameter: 32 km (Kepler), 29 km (Encke) Rukl: 30 Type: Complex Crater
Objects: Kepler, Encke
Observation 1: R1: Kepler deeper than Encke. Kepler, because of its size, gave me the initial impression it was shallower until I looked at it in more detail using a different eyepiece (9.7 mm vs. 4.7 mm). Kepler's floor and inner walls quite bright compared to Encke. C2: The tiny crater N was barely discernible on the west wall of Encke. It took patience; had to wait for the seeing to improve. |
Observation 2: R2: Kepler's rays extend north to Aristarchus, west to Reiner and Gamma Reiner, and overlaps some of the ejecta from Copernicus in the east. Very little ejecta visible to the south. C1: The extent of Kepler's ray system was sketched. |

I decided to have another look at these two craters.
IWLOP #013a – Eastern Mare Fecunditatis
A mare consisting of two contiguous, nearly round areas of dark Basaltic lavas. The northern part is three times larger than the southern and exhibits a number of dorsa. These lavas probably overlie an impact basin of pre-Nectarian age. Mare Fecunditatis covers 20 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below.
Location: 4.0 S 42-62 E Origin: Impact and Volcanism Size: 990 km. Rukl: 48 Type: Basin
Objects: Dorsa Mawson, Dorsa Geike, Dorsum Cayeux

R1: Dorsa Cato, Dorsa Cushman and Dorsa Cayeux were identified. Cayeux appeared to have 2 small crater in or very near it. All three appeared as if they could be part of an ejecta field from Taruntius, with all three heading south.
IWLOP #027 – Sinus Amoris (The "Bay of Love")
Long, slightly troughed, gentle drop in elevation to Mare Tranquilitatis. The flow of lava seems to have been from west to east, from the area around Maraldi, and then southward.
Location: 19.0 N 38.0 E Origin: Volcanic Size: 250 km Rukl: 25 Type: Bay
Objects: Sinus Amoris, Montes Taurus, Römer, Maraldi, Mons Maraldi, Hill, Carmichael

Transparency: Very Good (4)
R1: Montes Taurus appeared as a raised cratered area. Römer was a slightly elongated circular crater with wide slumped walls. Its central peak was wide and slightly elongated. The tiny crater in its north wall was quite bright compared to the coloration in the walls and floor.
R2: Maraldi is dark-floored with irregular SE and NW walls. Mons Maraldi, north of the crater, is a small oblong structure that is not very high.
R3: Hill and Carmichael are to the east. Their west interior walls were quite bright making them easy to identify.
IWLOP #054 - Abulfeda & Catena Abulfeda
This long crater chain begins at Abulfeda and continues to Rupes Altai. The origin of this chain, which is radial to no known basin or crater, is unclear.
Location: 17.0 S 13-21 E Origin: Impact Size: 62 km (Abulfeda), 210 km in length (Catena Abulfeda) Rukl: 45, 56, 57 Type: Crater, Catena

R1: Albulfeda has a flat floor with a small central crater. Whereas most of the walls look thick and terraced, the W wall looks steep/ridged. C1: Some craters on the north wall of Albufeda are smaller and shallower than others. |
IWLOP #089 - Timocharis
Prominent crater located near the middle of Mare Imbrium.
Location: 29.0 N 13.0 W Origin: Impact Size: 34 km Rukl: 21 Type: Complex Crater (CC)
Objects: Timorcharis, Feuillée, Beer, Heinrich, Dorsum Higazy, Dorsum Grabeau, Landsteiner
Others Identified: Archimedes, Bancroft, MacMillan, Montes Archimedes, Wallace
Observation 1: R1: Floor of Timocharis was completely in shadow during this session; couldn't see any of the floor. C1: Dorsum Higazy seemed to begin near Heinrich and curve around Timocharis until it approached Dorsum Grabeau. |
Observation 2: R1: Ejecta field around the crater but most of spray appeared to head towards Archimedes, almost reaching Feuillée and Beer. Only the east rim created a shadow on the east wall. Floor of Timocharis was completely visible. While the actual floor was small, walls were thick and ridged. The crater on its floor was quite visible but no evidence of a central peak. |
IWLOP #091 - Stadius
Ghost crater, subtle circular depression edged with incomplete low walls and crater pits. Stadius is slightly larger but much less prominent feature than nearby Eratosthenes. It is located roughly one crater diameter to the SW of Eratosthenes.
Location: 10.5 N 13.7 W Origin: Impact Size: 69 km Rukl: 32 Type: Compact Crater (CC)
Objects: Stadius, Eratosthenes, Mare insular
Others Identified: Montes Apenninus, Sinus Aestuum
Location: Home R1: Stadius appears as a ghost crater. The tallest part of Stadius' crater walls is in the NE and SW. The NW and SE crater walls don't appear - flooding? disintegration? or both? There were hints of numerous very small craters on its floor, but I wasn't sure. |

Just started to identify where I was on the lunar surface when our grandson William and his parents arrived. As he arrived, I had located Stadius. After showing him the crater and explaining its features, he used the hand controller to look for craters that interested him. They left around 8:30 PM.
My greatest success this evening? Apollo 16 landing site!! It was in a relatively “flat” area surrounded by a ring of craters. Beginning at the north and going clockwise: |
Alfraganus was also located while looking for Albulfeda.

Couldn't find anything "new" for the Explore the Moon (ETM) version but did view several previously viewed features for the ETM plus new ones for the Isabel Williamson Lunar Observing Program (IWLOP).
It was fun seeing features under a different light from previous observations. The "re-discovered" features viewed in a bit more detail were:
- Cassini and Vallis Alpes. Refer to IWLOP #68 - Montes Alpes & Vallis Alpes and Explore the Moon (Telescope) - April 19, 2021.
- Purbach with its line of crater that broke its north wall and continued onto its floor. Refer to IWLOP #73 - Regiomontanus & Purbach for more details.
- Walther to the south of Purbach also had an interesting line of craters across its floor. Refer to IWLOP #71 - Walther for details.
IWLOP #043 – Plinius
Complex crater with multiple central mountains. Appearance changes considerably under different lighting conditions. The darker area around the arcuate rilles highlight lava flows that predate the brighter lava of the sunken inner parts of the Mare Serenitatis Basin.
Location: 15.4 N 23.7 E Origin: Impact Size: 43 km Rukl: 24 Type: Complex Crater (CC)

R1: Plinius has a rounded central peak like a mini-crater, i.e., raised circular rim with an opening in the SW. West floor and wall of rim appears lighter than those of the east side and there may be 'hills' in the north.
C1: Ejecta blanket is on all side of Plinius. Refer to R1 regarding the hills.
C2: The arcuate rilles (including Rimae Plinius) north of Plinius appear to follow the "rim" of Mare Serenitatis.
C3: The Promontorium Archerusia has a high ridge that follows the rim of Mare Serenitatis; perhaps craters have also impacted the ridge. Dawes appears to have a large area surrounding it that is lighter than the surrounding mare floors; it also has a central peak.
IWLOP #044 – Lamont, Arago & Ross
Lamont is a large, ruined ghost crater near the centre of Mare Tranquilitatis. It is best viewed under low lighting. Apollo 11 landing site is to the south. Arago features two nearby domes designated Alpha (α) and Beta (β) that are impressive to view when visible.
Location: 5.0 N 23.2 E Origin: Impact and Volcanic Size: 75 km (Lamont), 25. 5 (Arago), 24.5 km (Ross), Rukl: 35

R1: Arago and Ross are SE and NE respectively of Julius Caesar.
R2: Lamont was barely visible on the mare floor. Flooded or worn down(?).
R3: Ritter and Sabine both located. Ritter B, C and D were visible. Schmidt was to their SW. They looked to be similar depths but Ritter's walls looked sharper. Sabine's south wall appears to have a break. There is a ridge from Rimae Hypatia that seems to affect it.
C1: The two nearby domes designated Alpha (α) and Beta (β) appear circular, lighter in colour than the Mare floor.
C2: Could not see the summit pits on the Arago domes at this time.
C3: The Ross peak is offset towards the E on its floor. The central peak of Arago appears to join to the north crater wall.
C4: Armstrong, Aldrin & Collins were all seen during brief periods of better seeing. Armstrong appears to be larger than the other two (refer to IWLOP #045 – Moltke & Rimae Hypatia for sketch of location of the 3 craters).
IWLOP #057 - Linné
The actual crater is a small difficult object but the bright halo around it is easy to spot. Linné has been described as a crater, cloud, crater-cone, or pit in a depression. The true nature of this bright and simple crater was settled using Apollo photos.
Location: 27.7 S 11.8 E Origin: Impact Size: 2.4 (actual crater); bright halo larger Rukl: 23 Type: Simple Crater (CS)
Objects: Linné

R1: Linné has a bright halo around a pinpoint. Stands out against the dark Mare Serenitatis floor.
R2: Viewed Linné eight hours before First Quarter.
C1: In brief moments of very good seeing, I was able to see a black dot just slightly off-centre.
Note: Don't know how much detail is required when asked to resolve its small crater. Could see Dorsum von Cotta to its south and the "Valentine Dome" to its NW. Numerous Dorsa on the Mare Serenitatis floor easily seen. The Mare Serenitatis floor, especially in the N-NW, is particularly darker that that of the dorsum and other parts of the E-SE.
IWLOP #059 - Manilius
Deep (3.2 km) terraced crater with high (2.6 km) central peak. Eratosthenian-age crater.

The Moon was adjacent to Pollux and Castor in Gemini.
Nothing “new” found for this program but did review some features and found others for the IWLOP. It was fun seeing features under a different light from previous observations. The first “re-discovered” features were Vallis Alpes in the Montes Alpes and Cassini to its south. Cassini was viewed quite well, this time with the higher magnification being able to see craters A and B on its floor. |
Next was Purbach with its line of craters that broke its north wall and continued onto its floor. Walther to its south also had an interesting line of craters across its floor.
I then revisited Julius Caesar at 9:18 PM. I had viewed it 2 years ago, but the floor could not be seen well at x250 magnification. This time I used a 4.7 mm eyepiece with a x2 Barlow to obtain x1000 magnification. It was then I noticed that the E and SE walls were in essence non-existent. There was a line of small craters across the east wall from SE-NW. There was a small crater on the NW wall.
This session was devoted to lunar observing. A couple of IWLOP objects were viewed.

Vallis Rheita was the target. This was 1 of 2 unobserved objects in the RASC Explore the Moon (Binocular) and one of many yet to observe for the Isabel Williamson Lunar Observing Program (IWLOP). I also found features not required for this session - Lacus Temporis, and the craters De La Rue, Strabo, Thales and Langrenus.
Found Vallis Rheita! It looked like a series of small craters running north to south, almost like a rib cage with no spinal column attached. The crater Rheita was at the north end with Mallet in the South. Refer to IWLOP #14 - Vallis Rheita for more details of this observation.
I was able to observe and sketch the following items for inclusion in IWLOP. Had lots of fun exploring the surface of the Moon for exciting new-to-me features.
- IWLOP #9: Endymion & Mare Humboldtianum: I was able to sketch the crater but the mare was only partially completed in this session.
- IWLOP #10: Snellius & Vallis Snellius
- IWLOP #12: Stevinus

8:50 PM: Lacus Temporis to its south, de la Rue, Strabo and Thales to its north. Identified in this area were: |
(Note: Sketch from |
9:00 PM:
Went more southerly to find Langrenus and Vendelinus plus part of the Mare Fecunditatis. I was able to identify several craters adjacent to these two craters: Atwood, Barkla (I think), Bilharz, Holden, Kapteyn, Lamé, Lohse, Noanubu.
Also had a great view of Mare Crisium and its craters and several other features:
Just as John Read suggested in the Moon at Noon, a smiley face appears when you consider Picard and Pierce as eyes and Dorsum Oppel plus the wall of Yerkes as the mouth.
Lacus Perseverantiae came as a surprise! Thought it was just a “space” between Firmicus and the SE of Mare Crisium. Wasn’t until I looked more closely at my lunar map that the area was identified.
IWLOP #077 - Montes Spitzbergen & Mons Piton
Picturesque small mountain range and an isolated mountain in Mare Imbrium. These peaks are interpreted to be relics of inner impact Mare Imbrium rings, and their shadow lengths are used to measure their heights. Montes Spitzbergen peaks rise to 1500 m whereas Mons Piton rises to 2250 m.
Location: 35.0 N 5.0 W Origin: Impact Length: 60 km (Montes Spitzbergen), 25 km diameter (Mons Piton) Rukl: 12 Type: Mounts

R1: Moretus is located SE of Clavius and has an oval shape. It's floor appears smooth except in its southern areas. C1: All 6 craters were located. Short is south, much smaller and shallower. Newton's east side was largely in shadow and the crater may be deeper than is Short. Curtius, Zach and Pentland form a triangle to the NE. Simpelius in the east has a central peak. None of the craters appear as deep as Moretus. |
IWLOP #094 - Montes Recti
Picturesque small mountain range in mare Imbrium that may be the remnant of an inner ring of the Mare Imbrium Basin.
Location: 48.0 N 20.0 W Origin: Impact Length: 90 km Rukl: 11 Type: Mount
Objects: Montes Recti
Location: Home R1: Montes Recti appears as a long line of all mountains with several segments - all separate, rising tall from the floor of Mare Imbrium. There are several lower rises at the base of the taller mountains. Montes Recti is located near Plato, Montes Teneriffe and Sinus Iridum. The surrounding mare floor looks very smooth. |

R1: Located Palus Epidemiarum. Capuanus has low NE walls with similar dark-coloured floor as does Palus. Ramsden was rounded with a steep rim and shadowed crater floor.
R2: Actually followed Rimae Hesiodus from Hesiodus to the NW ridge of Capuanus. Interesting how it cut through several lines of mountains and the floors of both Mare Nubium and Palus Epidemiarum.
C1: Rimae Ramsden began near Elger, formed a "Y" near Ramsden; one line continued past the NE wall of Ramsden then formed a backwards "N" shape between Ramsden and the mountains to its N-NW. Cichus was located on the E-SE shore, Weiss NE of Cichus, Dunthorne north of Ramsden and Rimae Ramsden, and Lepaute was west of Ramsden.
IWLOP #109 - Lacus Timoris
A small feature located in the mostly cratered southern highlands. It is long and narrow with a dark floor and inlets.

Transparency: Excellent (5)
Temperature: 4° C
SQM: 18.56
R1: Lacus Timoris has very flat dark floor with a few small craters. Haidinger was above the NE end of the Lacus and I could see three craters in close proximity - perhaps A, B and J (?).
R2: The Lacus is surrounded by mountains with several craters of various sizes on all its sides. The narrows of the Lacus seems to be created by higher peaks on either side. It is dark in colour compared to surrounding features.
C1: Hainzel, Hainzel A and C were in deep shadow; however, their NE rims facing the Lacus and Hainzel's SW inner rim were well lit.
IWLOP #088 - Gauricus & Wurzelbauer
Heavily eroded craters in the southern highlands region contrast with younger craters nearby.
Location: 33.8 S 12.6 W Origin: Impact Size: 79 km (Gauricus), 88 km (Wurzelbauer) Rukl: 64 Type: Eroded Craters
Objects: Gauricus, Wurzelbauer, Ball
Location: Home R1: Wurzelbauer had hilly terrain in its floor. Its NW and SE rims seem deteriorated. Several craters surround it. Gauricus has a smooth floor except for the very noticeable Gauricus F; several craters adorn its rim walls. |
IWLOP #082 - Davy & Catena Davy
Notable crater with a nearby chain of 23 very small craters likely caused by a fragmented comet or asteroid impacting the Moon.
Location: 11.0 S 7.0 W Origin: Impact Size: 35 km (Davy), 47 km long (Catena Davy) Rukl: 43 Type: Crater and Catena

Transparency: Good (3)
R1: Davy is a circular crater with a central peak; its east and west walls looked collapsed. Davy A was round, sharp-rimmed and had impacted the SE wall of Davy.
NOTE: I came across these features quite by accident when searching for the Fra Mauro Formation. Catena Davy was so clear! I was quite excited because a friend had searched for and found it a night or two before and we could now compare notes. |
IWLOP #090 - Pitatus
Large Nectarian Age crater with fractured walls located on southwestern edge of Mare Nubium.
Location: 29.8 S 13.5 W Origin: Impact Size: 97 km Rukl: 54, 64 Type: Complex Crater (CC)

Temp: 5º C
SQM: 18.63
R1: Pitatus on southern border of Mare Nubium. Very irregular and poorly defined rim due to fractures and impacts. Large central peak is off-centre. Walls in the northwest are particularly eroded.
C1: Could easily see Rimae Pitatus along the NE and East side close to the rim. Also saw a bit of the Rimae in the NW. Could see some approaching the off-centre peaks but most was seen just inside the crater wall on the floor. The eastern floor was just a bit darker than the western floor.
IWLOP #093 - Fra Mauro Formation
Eroded crater partially filled by ejecta blanket from the Mare Imbrium impact. The Apollo 14 landing site is just north of Fra Mauro crater.
Location: 6.0 S 17.0 W Origin: Impact Size: 95 km Rukl: 42, 43 Type: Ejecta blanket
Objects: Fra Mauro, Apollo 14 landing site, Parry, Bonpland, Rimae Parry, Dorsum Guettard
Others Identified: Guericke, Bundt, Tolansky
Location: Home R1: Fra Mauro is almost flooded and has eroded crater walls; some areas of the wall are non-existent. Only the rim in the NE seems to remain; Bonpland and Parry have impacted the southern walls. Crater floor appears rough. Apollo 14 landing site just north of the crater appears to be a higher elevation. |
C1: Rimae Parry has more than one section:
* Section 1 crosses the SE rim of Parry in a NE direction before crossing the east rim and continuing a short distance into the Mare.
* Section 2 extends from the crater Tolansky across the west side of Parry and into the Fra Mauro crater.
* Section 3 crosses the north rim of Bonpland and into Fra Mauro.
C2: Dorsum Guettard begins at the southwest rim of Bonpland and ends somewhere around Crater D. It does have a slight curve to it.
IWLOP #099 - Longomontanus

C1: Bright rays from Proclus go eastward into Crisium; none towards Palus Somni.
NOTES:
1- The extent of the differential rays east and west of Proclus were drawn in the sketch; I didn't used the IWLOP template.
2- Palus Somni had a different shade/hue in colour compared to surrounding formations. It also appeared rough in terrain with numerous ridges and/or craters.
3- Proclus was oval-shaped. It's NW rim appeared shallow and had numerous ridges that were very white. The floor appeared very pale grey.
IWLOP #029 - Fracastorius
Since this crater intersects the Nectarian Basin wall, it formed after the Nectarian Basin impact but before the area was flooded with lava.
Location: 21.2 S 33.0 E Origin: Impact Size: 58 km Rukl: 58 Type: Complex Crater (CC)

R1: Oval/Almond shape to the crater on south shore of Mare Nectaris. North wall virtually non-existent with similar colour to the Mare.
C1: Crater M located near the centre line in lower half of the crater. Crater L was located in the upper half just off centre. The rille seemed to pass just north of crater M, extending east towards a small crater and ending on the crater wall near crater D.
NOTE: The crater floor north of the rille into Mare Nectaris was darker than the floor south of the rille. There was also a bright line (ejecta?) that ran NE to SW, especially noticeable below crater D.
IWLOP #031 – Piccolomini
Piccolomini is thought to be an Upper Imbrian Era crater superimposed on Rupes Altai and on secondary craters related to the Imbrium Basin (most of the smaller, older craters nearby).
Location: 29.7 S 32.2 E Origin: Impact Size: Crater 88 km Rukl: 58, 68 Type: Complex Crater (CC)

R1: Piccolomini easily located at the southeast terminus of Altai Scarp. Large central peak for its size. Terraced walls. There was a "flowerette" of 5 or so craters to its north plus an additional 4 craters.
C1: The southern wall seemed gradually terraced or more worn than the other walls.
Observation 2: No details recorded. |
IWLOP #049 - Sacrobosco & Playfair
Sacrobosco is a pre-Nectarian crater and Playfair is Nectarian. The eroded Playfair G directly west of Playfair is pre-Nectarian since it is covered by deposits of probably Nectarian age. Sacrobosco and Playfair are located at widely separated longitudes so you may need to wait for the terminator to observe them both at the same time.
Location: 23.7 S 16.7 E Origin: Impact Size: 98 & 48 km Rukl: 56 Type: Complex Crater (CC
Objects: Playfair, Playfair G, Sacrobosco

R1: Playfair appears to be deeper than Sacrobosco and Playfair G. The latter 2 have rims that appear flatter and have been hit by objects to create numerous craters on their floors and rims. Sacrobosco's west rim is very terraced.
C1: The 2 craters in Playfair are in the NW quadrant. The 4 craters in Playfair G form a loose square around the centre point. Very tiny craters in all 6 cases. Also, it appears that Playfair was formed after Playfair G as Playfair changes the shape of G's rim.
IWLOP #061- Rima Hyginus (aka Archer's Bow)
One of the most impressive of the many rimae on the lunar surface. It extends from Rima Ariadaeus in the east to Rimae Triesnecker in the west.

R1: The crater Hyginus was found in the middle of the curved Rima Hyginus. R2: South of the Rima's eastern tip are Godin and Agrippa. Both craters appear to be deep with central peaks. The western rims appeared steeper than the eastern rims. Godin's peak looked sharper that Agrippa's peak. |
NOTE: The Rima is also known as the "Archer's bow." Hyginus and Rima Hyginus are east of Ukert where the "Lunar V" can be located. C1: There is a small crater on the northern rim of Hyginus, giving the crater an almond shape. The Rima appears to enter Hyginus halfway on its east side, and splits through the lower portion of the crater. The Rima isn't continuous.

R1: Albategnius is adjacent to Ptolemaeus and Alphonsus. It has a central peak slightly off-centre. The eastern wall has numerous oval craters. Floor is relatively smooth. The scar on the east wall looks like a valley that ends in two craters. C1: The saucer-like depression on the floor of Albategnius was near the middle of the crater, with the central peak appearing to be on one of the edges of the saucer. There was a slightly darker colour in the saucer. |
IWLOP #067 - Werner & Aliacensis
This is a Nectarian age crater that still retains an off-centred peak.
Location: 28.0 S 3.3 E Origin: Impact Size: 70 km (Werner), 80 km (Aliacensis) Rukl: 55, 65 Type: Complex Craters (CC)

These craters are adjacent to Walther and Regiomontanus.
R1: Werner and Aliacensis both have steep terraced walls and slightly off-centre central peaks. The north wall of Aliacensis appears to have been impacted by Werner's ejecta. Wall not as distinct and some ejecta appears on its floor, almost like a slight depression between the two.
R2: Both Tycho and Werner have sharp-rimmed walls. During the Full Moon phase, Tycho's ejecta is seen splattered over this area (and beyond). Both have a series of terraces on the crater walls.
C1: Werner D appears as bright crater on the north wall of Werner. Werner seems to have one large off-centre peak with two smaller ones. Aliacensis has an off-centre peak near where the change of colour in the floor appears.
A lava-filled crater located near the edge of Oceanus Procellarum.

Windless night with no cloud cover during the observing session. Jerry was out with his telescope for astroimaging purposes. Waxing Moon at 99.9% illumination.
C1: Hubble is east of Mare Crisium, close but not on the edge of the limb. I used Mare Anguinus and Eimmart as the start points for location as they appeared to be approximately at the same latitude. Hubble looked shallow and elongated (perhaps due to libration?). No peaks or craters visible at this illumination level.
A sharply-defined crater located in a remote area of the Moon.

I had been waiting quite a while to view this crater! Knew it was near Babbage and Sinus Roris. A real treat to finally see it!
C1: Markov was a slightly elongated crater with a pointed southern wall. Oenopides was easily located to Markov's north. Could not see the floor of Xenophanes and Volta but did locate their walls on the terminator. Appeared to be quite tall.
IWLOP #042 – Sinus Asperitatis

R1: This area has a rough surface, especially between Hypatia and Theophilus. A particular raised rough area between Torricelli and Theophilus - perhaps remnants of a crater wall (?). Toricelli appears to be shaped like a piece of candy corn.
C1: Torricelli looks like a crater within another well worn crater. One of the walls was observed as obliterated due to an overlapping impact.
IWLOP #103 - Reinhold & Lansberg
Mare Cognitum, the “Known Sea,” was named in 1964 to mark the successful flight of the Ranger 7 spacecraft, which sent back the first detailed television pictures of the lunar surface. Kuiper, located in central Cognitum, is an excellent example of a small, simple crater.
Location: 3.3 N 22.8 W Origin: Impact Size: 48 km (Reinhold), 39 km (Lansberg) Rukl: 31, 42 Type: Simple Crater (CS)

R1: Montes Riphaeus is on the NW border of Mare Cognitum. It separates this Mare from Oceanus Procellarum. The mare floor on the east side of the Montes is dark compared to the ejecta to the west where Euclides is located. Note: The rounded/curved edge of the mountains on the Mare Cognitum side made it look a bit like the remnants of an old crater. The north range also looked like it had been a crater rim. C1: A large dome appeared SE of crater D and N-NW of the western branch of Montes Riphaeus. |

No clouds and a light breeze. Because of the trees in our yard, I went to our neighbour’s driveway for an unimpeded view. Used the 12 mm eyepiece first but resorted to the 9.7 mm.
Cook looked like a very shallow crater; the sides did not provide any significant shadows. A crater appeared just inside its SW floor and there was one on its southern wall. Its floor appeared to be the same coloration as Mare Fecunditatis.
Montes: Pyrenaeus, Secchi
Maria, etc.: Dorsa Cato
Craters: Cook, Taruntius
Craters not on ETM List: Colombo, Magelhaens, Messier, Messier A, Secchi
Named for British naval captain and explorer James Cook (1728-1779) who spent 4 winters (1758-1762) in Halifax, NS, preparing charts and sailing directions for eastern Canadian Seaways, 5 years (1763-1767) carrying out the first accurate coastal survey of Newfoundland, and he established the location of the Coast of British Columbia (in 1778).
Flooded crater in western Mare Fecunditatis near Colombo.

No clouds, light breeze. Transparency created a small bit of distortion. Overall good viewing from our next door neighbour's yard - they have no trees!
Cook was a low-rimmed crater. There was a small crater on its south rim and ridges to the NW. The NE and East rim seemed more shallow than the western rim.
IWLOP #007 – Furnerius & Fraunhofer
Furnerius is an old eroded crater with Nectarian ejecta on its floor. Compare this ancient crater with younger Petavius to the northeast.
Objects: Furnerius, Furnerius B, Fraunhofer, Fraunhofer B
Others Identified: Rimae Furnerius
Observation 1:

C1: Rima Furnerius appears as a very faint ridge just above crater B and goes across the crater floor. Showed a very light and thin shadow. Petavius A was also located on the crater wall, and almost appeared as if Rimae Furnerius pointed to it.
IWLOP #013b – Central Mare Fecunditatis
A mare consisting of two contiguous, nearly round areas of dark Basaltic lavas. The northern part is three times larger than the southern and exhibits a number of dorsa. These lavas probably overlie an impact basin of pre-Nectarian age. Mare Fecunditatis covers 20 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below.
Location: 4.0 S 42-62 E Origin: Impact and Volcanism Size: 990 km. Rukl: 37, 48 Type: Basin
Objects: Messier, Messier A, Dorsa Cato, Taruntius, Secchi, Montes Secchi

R1: While looking for another feature, I came across Messier and Messier A. Two individual ejecta lines were very noticeable across the Mare Fecunditatis floor heading westward to end just above the crater Lubbock. Dorsa Cato was also observed east of Montes Secchi, going basically south from Taruntius towards the Messier craters. There were 3 dorsa appeared as part of the ejecta field from Taruntius: (W to E) Cato, Cushman, Cayeux. |
IWLOP #013c – Western Mare Fecunditatis
A mare consisting of two contiguous, nearly round areas of dark Basaltic lavas. The northern part is three times larger than the southern and exhibits a number of dorsa. These lavas probably overlie an impact basin of pre-Nectarian age. Mare Fecunditatis covers 20 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed below.
Location: 4.0 S 42-62 E Origin: Impact and Volcanism Size: 990 km. Rukl: 48, 59 Type: Basin
Objects: Lubbock, Goclenius, Colombo, Gutenburg
Others Identified: Colombo A, Gutenburg A, C, D, E, J, Montes Pyrenaeus
Observation 1: R2: Goclenius appeared pear-shaped with the NE crater wall non-existent. Colombo and Colombo A also viewed with Gutenburg. Gutenburg E looked to be created by an impact that obliterated that portion of the Gutenburg's east wall. Gutenburg A impacted the outer west rim of the crater. Gutenburg C's impact obliterated the southern rim and created ejected to its south as well. NOTE: Lighting and magnification not sufficient to complete this objective. |
Observation 2: R1: Lubbock located in the triangular-shaped highlands. Appeared flat, virtually no rim C1: There were 10 ghost craters that could be seen in the immediate area of the mare floor east of Goclenius. |
IWLOP #028: Capella & Vallis Capella
Interesting crater with a valley running through it; located on the northern edge of Mare Nectaris.
Location: 7.6 S 34.9 E Origin: Multiple linear impacts Size: Crater 49 km, Vallis 110 km Rukl: 47 Type: Complex Crater (CC) & Valley
Objects: Capella, Vallis Capella, Isidorus, Censorinus

R1: Very large central peak. Valley runs NW to SE between peak and crater wall.
R2: Capella appears shallower than Isidorus and its western wall created a wide shadow in Isidorus' floor. Isidorus looked to have 2 craters on its floor.
C1: Could make out 8 craters only along Vallis Capella.
C2: Censorinus is very small and circular compared to the larger Crater A next to it. Area is brighter around its rim.
IWLOP #040 – Rupes Altai
This incredible scarp is the continuous southwestern outer rim of the Nectaris Basin. Spectacular at low Sun, it varies from 3.5 - 4.0 km but tapers off and is more broken southward toward the crater Piccolomini and northward past crater Borda.
Location: 16-29 S30-21 E Origin: Tectonic Size: 480 km. Rukl: 57, 59, 46 Type: Scarp
Objects: Rupes Altai, Cyrillus, Catharina, Colombo, Santbech, Tacitus, Kant, Hypatia
Others Identified: Ibn Rushd, Mädler, Mons Penck, Pons, Polybius
Location: Home R1: Rupes Altai was first observed on May 28, 2020 during the waxing crescent phase when it was well-lit. It was again observed on March 21, 2021 during the 1st Quarter when observing Piccolomini (IWLOP #031). C1: Tacitus, Kant and Hypatia were located. Altai Scarp appeared continuous in the SE portion but appeared worn/non-existent as it continued N towards Tacitus, Kant and Hypatia. Note: Rupes Altai was first noticed because of the well-lit Altai Scarp; it wasn't in shadow. |
IWLOP #047 - Delambre
Delambre is located near the edge of Mare Tranquilitatis and not too far from Statio Tranquilitatis. Note the sharp rim and terraced walls of Delambre. Try to see this crater at a high sun angle.
Location: 1.9 S 17.5 E Origin: Impact Size: 52 km Rukl: 46 Type: Complex Crater (CC)

R1: Located the 1969 Apollo 11 landing site above Rimae Hypatia and NW of Moltke on Mare Tranquilitatis. The Mare floor looked very flat and smooth at this magnification for the Apollo landing.
R2: The twin craters Theon Junior and Theon Senior were easily located west of Delambre. Both are deep, round, and are much smaller than Delambre. Shadows covered their crater floors.
C1: Delambre D was located on the north wall of Delambre. It appeared more as a slight bump to the otherwise smooth roundness, as well as only see a slight discolouration at this location. One wall of Delambre H and part of the crater floor were barely visible just outside Delambre's NW wall, between Delambre and Theon Senior.
After almost a year of inactivity regarding the ETM, thought it was time to get back at this.

IWLOP #006 – Petavius
A lower Imbrium crater with a massive, complex central peak and floor uplift as indicated by rifts. This is an excellent example of a "floor fractured" crater.
Location: 25.3 S 60.4 E Origin: Impact Size: 177 km. Rukl: 59 Type: Complex Crater (CC)
Objects: Petavius, Rimae Petavius, Wrottesley, Hase
Others Identified: Vallis Palitzch, Petavius A, Petavius B, Hase A
Location: Home

Time: 9:40 PM ADT
Equipment: 6" Dobsonian, 9.7 mm eyepiece + x2 Barlow
Magnification: x250
Transparency: Good (3)
Seeing: Good (3)
R1: Petavius quite a large crater with a very large and irregularly shaped central peak.
R2: Rimae Petavius was very evident and easily identified. It went basically across the crater from the central peak (refer to sketch).
R3: Wrottesley appears to be NW to or on the outer part of Petavius's wall and has a faint central peak. It's not as terraced as Petavius. The shadow on its SE wall seems to extend outwards from the crater - perhaps from ejecta (?).
C1: I was very excited to see how easily Rimae Petavius could be seen. I followed it to the inner eastern rim and out the south wall.
C2: Noticed dark materials at 1 and 5 o'clock on the crater floor.
C3: Rimae Petavius continued southward until it met with the crater Hase (refer to sketch).
IWLOP #024 – Atlas & Hercules
Two prominent craters that share the same region. There is some debate about the age of Atlas but it is probably Upper Imbrium while Hercules is Eratosthenian.
Location: 46.7 N 44.4 E Origin: Impact Size: 69 km Rukl: 15, 14 Type: Complex Crater (CC)
Objects: Hercules, Atlas
Location: Home

Equipment: 6" Dobsonian, 9.7 mm eyepiece +x2 Barlow
Magnification: x248
Seeing: Good (3)
Transparency: Good (3)
R1: Both Atlas and Hercules appear oval. Atlas is much shallower than Hercules, perhaps due to the infilling as suggested in the IWLOP notes.
R2: Atlas has terraced walls, especially in the southern area where it almost appears to flatten as it approaches the floor.
C1: Hercules G was found in the brighter southern Hercules floor.
C2: Hercules walls were high with multiple terraces. The SE of the crater floor was noticeably darker than the rest of the floor.
C3: Multiple central hills in Atlas could be seen quite well. Could see a hint of 3 of the 5 of the south rilles. A portion of the north crater floor appeared darker. Southern wall may be more terraced than the northern portions.
IWLOP #035 – Jansen
Jansen is a low, mare-flooded crater. It dates from the Pre-Nectarian Era.
Location: 13.5 N 28.7 E Origin: Impact and Volcanic Size: 23 km Rukl: 36 Type: Complex Crater (CC)
Objects: Jansen, Jansen Y, Sinas, Maskelyne, Dorsa Barlow
Others Identified: Beketov, Cajal, Carrel
This session was conducted as part of the lunar observing session - Lunar Session - April 15, 2021
Observation 1: R1: Jansen is a very shallow crater with a floor much darker than the surrounding area. C1: The small crater Jansen Y could not be seen. |
|
Observation 2: C1: The small crater Jansen Y was seen on the crater floor. |
IWLOP #036 – Lacus Mortis & Bürg
Lacus Mortis, the "Lake of Death," is an ancient crater flooded by lava and is almost hexagonal in shape.
Location: 45.0 N 27.0 E Origin: Volcanic and Impact Size: Dorse 150 km, Mons 40 km Rukl: 14 Type: Lacus, Complex Crater (CC)
Objects: Lacus Mortis, Bürg, Plana, Mason, Lacus Somniorum, Rimae Bürg

Transparency: Good (3)
R1: Lacus Mortis is west and adjacent to Atlas and Hercules. Looked to be an old crater perhaps(?).
R2: Bürg had steep sides that created long shadows over the central peaks.
R3: Plana had as deep thick east wall but the west wall seemed disintegrated. Plana joined to Mason. Mason's north wall was virtually non-existent; another mountain on its E-SE wall. Plana had a central peak; Mason did not. Both seemed to form the southern border of Lacus Mortis.
C1: Rimae Burg began where shadows showed on the west side of Lacus Mortis and headed NE above Bürg.
IWLOP #113 - Promontorium Kelvin and Rupes Kelvin
A large, well-defined promontory in Mare Humorum and a scarp located nearby on the edge of the same Mare.
Location: 27.0 S 33.0 W Origin: Impact and Tectonic Length: 50 km (Promontorium Kelvin), 86 km (Rupes Kelvin)

R1: Promontorium Kelvin was well lit and appeared to be joined to Rupes Kelvin by a narrow isthmus. Rupes Kelvin was less well-defined; appeared as a broken up range of mountains.
R2: Rimae Hippalus runs north to the degraded crater Hippalus. It looked like a thin valley with a rim.
R3: There was an extensive system of wrinkle ridges in eastern Mare Humorum. Several formed a semi-circle of sorts that ran from Gassendi in the north to Loewy to Pulseux to Vitello in the south.
C1: Rimae Hippalus runs north to the large crater Agatharchides. The crater's northern rim appears broken/fragmented.
IWLOP #116 - Gassendi
Nectarian Era, eroded crater with extensive system of rimae on its floor.
Location: 17.5 S 39.9 W Origin: Impact/Tectonic Size: 110 km Rukl: 52 Type: Complex Crater (CC), Rille
Objects: Gassendi
Others Identified: Doppelmaier, Gassendi A, Gassendi B, Hippalus, Lee, Loewy, Rimae Mersenius, Rupes Liebig, Vitello
Observation 1: Moon Phase: Waxing Gibbous (81.5%) R1: Gassendi was easily found on the north shore of Mare Humorum. It appeared to have 3 central peaks. Gassendi A & B also visible. Crater A appeared to have a tall crater wall that created a large shadow on the floor whereas crater B appeared shallow by comparison. C1: The rilles were in greater number on the west side and almost suggested 2 or 3 craters in the past with varying depths. |
Observation 2: R1: Observed mini-craters on Gassendi's floor plus one on its west wall. Looked like the "time" was 4:40 PM. I didn't take the time to sketch this in detail. |

Observing with grandson William who was with us for a sleepover. We spent some time going through some the constellations and asterisms he knew. For instance, because Vega was one of the first stars to be seen, he could easily find the Summer Triangle, and we saw the beginnings of the Milky Way showing up.
He has known about the Big Dipper since he was little. He also remembered Cassiopeia that he first saw at Blomidon Provincial Park two years ago (although he calls it the "William" constellation because of its 'W' shape). He was also shown the double stars Mizar and Alcor at Blomidon and during this evening's sky tour.

I along with Tony Schellinck, Paul Heath, Melody Hamilton and a group of others noticed the strange arrangement of the 4 Galilean moons - like butterfly wings. I made rough notes about this but couldn't find this particular lunar formation; the OH had no mention of it and SkySafariPro showed the moons in a line with Europa on one side and Io, Ganymede and Callisto on the other.
No explanation for this pattern. Perhaps Europa (upper right of the 4 sketched) formed the shape with three GAIA-designated stars and we didn't look further for the other 3 moons (?).

First found this with Melody Hamilton and Dave Chapman. Very clear night, dew starting to form. The comet was found two ways:
a) Melody:
Visually found NGC869/NGC 884. With them in my lower binocular FOV, I looked for a "7" laying down on its side, then looked up from the the left side of my FOV at about 10 o'clock. There it was ! Including a slight tail.
b) Dave:
Look at Cassiopeia's star Segin (epsilon Cass). With Segin centred on my FOV, 21P could be found at approximately 8 o'clock.
Win-win! Two ways to find the same location. After I returned home, I identified the four stars in the "7" lying down.

Jupiter (in Scorpius) Clearly identified Europa and Callisto. Io and Ganymede were not seen. SkySafariPro suggested Io was very close to the Moon's west limb but I couldn't separate the moon from the planet. Ganymede must have been occulted by the planet. |

83.4% Moon. Easily located Mares Crisium, Imbrium, Serenititatis, Tranquilitiatis, Nectaris and Sinus Iridum.
What stood out visually in the binocs were the Jura Mountains on the northern shores of Sinus Iridum – they were on the terminator and the light was bright on its slopes to the mare floor. Couldn’t help but return again to view Iridum and the terminator. Showed both Linda and Mark at different times.
Jupiter (in Scorpius) Viewed Jupiter while standing on their dock. The four Galilean moon were visible, Io fairly close tot he planet on one side with the other 3 (Europa, Ganymede and Callisto) on the other. |

Found - handwritten notes about this evening. I had noted the items observed during this evening in my 'draft' log book intending to write it up in the compiled log book - but failed to do so. There apparently was lots of light at the horizon and that it seemed murky.
All the items above were located and identified. The lower part of Scorpius' tail was in the area of the murky horizon.
It was noted that all 4 of the Galilean moons of Jupiter were visible in the binoculars. Jupiter was about 6.5º above Antares towards Sabik (in Ophiuchus). On the east side were Callisto and Europa. On the west side were Io and Ganymede. I noted that Io was relatively close to Jupiter compared to the other 3.
Saturn was located near the handle of the Teapot in Sagittarius. The rings were tilted (NW to SE). I made no note of any moons identified.

We were camping with the Chapmans again for our Annual Big Muise Island Star Party. New Moon. Breezy enough to keep the mosquitos away. Occasional clouds.
Delphinus Jerry, Dave and I could easily see all 5 stars of the constellation. Jerry then told us about how the 4 stars forming the 'head' of the dolphin was also an asterism - Job's coffin. It is referred to as a coffin because of its long, box-like shape. Job’s Coffin is formed by four relatively bright stars in Delphinus: Rotanev (β Delphini), Sualocin (α Delphini), γ Delphini ,and δ Delphini. The two unusual star names – Rotanev and Sualocin – come from the Latinized name of Italian astronomer Niccolò Cacciatore – Nicolaus Venator – written in reverse. A fifth star, Aldufin (ε Delphini), forms the dolphin's tail. |
Lore re Job's Coffin: 1- The dolphin constellation represents Poseidon’s messenger. When the sea god courted the nymph Amphitrite, one of the Nereids, she resisted his advances and took refuge among her sisters. Poseidon sent messengers to find her and bring her to him, among them a dolphin. The dolphin found the nymph, soothed her and brought her back to the god. The two were later married. Poseidon decided to honour the dolphin and placed his image among the stars. 2- It was Apollo, the god of poetry and music, who placed the dolphin among the constellations for saving the life of Arion, a poet and musician born on the island of Lesbos, whose skill with the lyre made him famous in the 7th century BC. Arion was sailing back to Greece after a concert tour of southern Italy when the sailors who were also on the ship started plotting to take the money he had earned. Surrounded, Arion asked them to let him sing one last song. The sailors allowed this, and Arion’s music drew several dolphins to the ship. As he played, the dolphins swam alongside the ship and Arion decided to take a leap of faith and he jumped overboard. One of the dolphins saved him and carried him all the way back to Greece. In this version of the myth, Apollo placed the dolphin next to the constellation Lyra in the sky, and Lyra represents Arion’s lyre. |

Jupiter (in Scorpius) Only 3 Moons were seen adjacent to Jupiter - Callisto, Io and Ganymede. Europa was being occulted by Jupiter. |

M55 Looking at the S&T Pocket Star Atlas, I noticed M55 between the Teapot handle and the bottom of Capricornus. I started with Ascella and worked my way towards ω Capricorni. I accidentally found it using averted vision - showed Dave where it was located on the star map and he found it as well. A very faint fuzzy. In looking for info on this object, it was suggested to follow the arc of stars from τ Sagittari to ψ Sagittari to χ Sagittari to h2 (52 Sgr) and then go straight down to M55. |
|||
Satellite (ISS) It appeared near Arcturus then disappeared just past Altair. Very bright and very fast! And very large compared to other satellites. |
Satellite First noticed while on its path between the Keystone of Hercules and Corona Borealis. It Passed through Ophiuchus then disappeared between Antares and Deschubba. |
||
Meteor |
Noticed it coming across the top of Ophiuchus and travelling across a corner of the Keystone of Hercule. It disappeared just past the Keystone. |
||
M70 Used my binoculars to attempt to find M70 approximately midway between Ascella and Tau Borealis in the Teapot. I could find M69 and M54 but M70 alluded me once more. Use a telescope next time! |
|||
M4 + Scorpius Scorpius was identified visually in the S-SE with Antares clearly visible naked eye and with binoculars. Could see as far down the tail/stinger as ε Scorpii before the remaining stars of the constellation disappeared in the murkiness. Was able to locate M4 adjacent to Antares. |
|||
|
|||
M69 (Globular cluster) There was a curved formation of 3 stars from Kaus Australis towards the inside of the Teapot. Just above this curve was M69. I hadn't been able to find M69 for a couple of years, despite good seeing and visibility. Perhaps my cataract surgery made a difference(?). |
Note: The 3 stars starting at Kaus Borealis are HR 6893, HD 169706 and HR 6936. |
||
M54 / NGC 6715 / Summer Rose Star I had been unable to find this object for a couple of years. Focused my binoculars with Ascella at 9 o'clock in my FOV. Found M54 with averted vision! Finally.... success! It was very faint but it was found. I returned to this location later in the observing session to confirm I could find it again. |

We were camping with the Chapmans again for our Annual Big Muise Island Star Party. Around 10:35 PM, lightning periodically lit the sky; Jerry determined the storm was centred over St. Stephen, NB. A little breezy but it did keep the mosquitoes away. The New Moon was expected at 12:12 AM ADT.
Varying degrees of transparency and seeing as the night progressed. Clouds occasionally covered the Teapot that affected the visibility of the stars and globular clusters in the area.
Lyra Vega appeared overhead around 9:35 PM. Could easily see the locations of β, ζ, and ε Lyrae. Did not pay particular attention to δ and γ Lyrae. |
|||
Delphinus At this time, sections of the sky were clear but very murky near the horizon. Used naked eye to find and identify all 5 stars item constellation. |
|||
Scorpius Scorpius was identified visually in the S-SE although its tail wasn't visible due to the murkiness at the horizon. The red Antares was clearly visible naked eye and with binoculars. Dave pointed out the 2 stars adjacent to Antares (σ Scorpii and τ Scorpii) both had the same name - Al Nayat. Could see as far down the tail/stinger as ε Scorpii before the remaining stars of the constellation disappeared in the murkiness. |
|||
Jupiter (in Scorpius) Observation 1 with Binoculars: Observation 2 with Telescope: |
|||
M4 / NGC 6121 Using the binoculars, I could find the small fuzzy M4 at 4 o'clock to Antares. |
M6 / Butterfly Cluster I used Kaus Borealis in the Teapot to find M6 approximately 1.5 FOV away. The grey fuzzy was visible but not as clearly defined as in the past due to the haziness in that part of the sky. |
||
Keystone Hercules + M13 / Hercules Globular Cluster I found the Keystone of Hercules almost at the zenith and located all 4 of its stars. Using binoculars, I was able to find the small grey fuzzy between η Herculis and ζ Herculis without any difficulty. |
|||
M7 / Ptolemy's Cluster / NGC 6475 In clearer skies, the cluster would have shone almost as brightly as the Pleaides. It was easily located naked eye as a dullish object. I followed the line from Ascella to Kaus Australis in the Teapot and went out 1.5 FOV. The murkiness creating poor seeing and transparency in this part of the sky was quite evident. |
M8 / Lagoon Nebula Made a line from Kaus Australis through the mid-point of the line at the top of the spout, then travelled an equal distance to M8. Could easily see the bright open cluster of M8; could also see M20 in the same FOV. M21 is very close to M20 and therefore easily found within the same FOV. |
||
Saturn (in Sagittarius) Observation 1 - Visual: Observation 2 - Binoculars: Observation 2 - Telescope: |
|||
M11 Discovered that M11 is located in the Scutum Star Cloud below a dark nebula Bernard 111. I easily found a 'square' portion of the Cloud with 2 bright objects in its upper border. With binoculars, I found M11 as the left bright object and guessed (with star charts help) that the right bright object was β Scutum. I still consider M11 as the "golf ball" next to an asterism shaped like a golf club. Note:
|
|||
M22 Again, I used Kaus Borealis to locate M22 within the same FOV. It appeared as a small grey fuzzy with no particular details in binoculars. |

NOTE: With effort, I was also able to identify Maurolycus G, L, A, J, M, F and D. Also identified Barocius B and C easily.
|
Maurolycus: Very easily could see the main and secondary central peak. At least 4 craters on the floor and 2 with direct impact on the rim. Ridging or slumping of the east wall was evident.
Breislak: Its NE rim showed at least 4 craters on its wall or just inside on the floor. There were 2 craters on its SE rim and a small one in the NW.
Clairaut: More definitive this session. Two large craters on its floor. Three small craters on the outside of its SW rim. Crater A had a direct impact on its SE rim while Crater E hit just on the edge of the NW rim.
IWLOP #051 - Gemma Frisius
This crater features an unusually high wall of over 5 km.

R1: Both Gemma Frisius and Goodacre are generally round. Goodacre has its rim interrupted only in the S-SW whereas Gemma Frisius has craters of varying sizes on all of its rims.
R2: Just over the western wall of Gemma Frisius are the craters D, G and H in a line, going from SW to NE. G & H are shallower than D.
C1: To the NW is Poisson with disintegrated crater walls and its unsmooth floor. Crater A and the grouping of U, V, K, Q between it and Gemma Frisius were easily identified.
NOTE: The crater combo of Gemma Frisius, Goodacre and Crater D makes it look like Minnie Mouse with a bow in her hair! However, you might never know it from my sketch!
IWLOP #058 - Cuvier
Crater with a smooth floor. Cuvier is located almost due south of the prominent crater Maurolycus (Rukl 66) in a heavily cratered area of the Moon that is an interesting challenge to navigate.

No clouds or wind. Relatively warm night.
R1: Located Cuvier SE of Heraclitus. Slight oval shape with crater impact on NE rim. Five craters curved to the SE - Q, E, A, E, B). Also found L & H on NE rim. |
C1: Found all 3 craters (Baco, Asclepi and Tannerus) to the east and SE.
Baco: worn down rims, oval shaped, smooth floor. Several craters near its rim.
Asclepi: SE of Baco. Crater floor appeared smooth.Easily identified sub-craters B, D, G, H along with A and E. Looked like a squished diamond shape. Tannerus: Sub-craters formed a right angle with Tannerus at the corner. |
|
C2: Further SE, I found Mutus and Manzinus and to the south Jacobi and Kinau. I knew Kinau formed a triangle with Mutus-Manzinus and it wasn't easily found. The Moon was favourably librated so could identify others even further south. Mutus: Craters A, B and V found on smooth floor. Steep eastern rim versus the ridged west rim. Crater A adjacent to the rim. Crater B just off-centre to the west and completely on the crater floor. Crater V was in the east and was the largest of the three. |
|
Manzinus: Craters D, E and G on SW sloped rim, plus C and N.
|
Jacobi: Impact crater O on northeast rim and J on southwest rim, plus N, K, W on the crater floor. |

Seeing: Very Good (4)
Transparency: Very Good (4)
R1: Stöfler has terraced walls in its western rim. Most of the adjacent secondary craters also have terraced walls.
R2: There are two distinct craters on either side of Faraday. The east crater appears deeper and smaller than the western crater with more terracing in the western crater.
R3: The oval-shaped Licetus is southeast of Stöfler whereas the odd-shaped Heraclitus is in the southwest. Heraclitus appears to have a small dividing mountain or ridge.
R4: To the north are Fernelius and Kaiser. Fernelius shares a ridge with Stöfler and also has a crater on its west rim. There is also a small crater where the crater rims of Stöfler and Fernelius meet. Kaiser also has a small crater to its NE.
These objects were confirmed on another evening when viewing Stöfler and Faraday.

No wind or clouds. R1: Lexell has a central peak and a very eroded northern edge. Hell is very deep and has a well-defined rim. Deslandres appears to have been impacted several times on its rim and its floor, giving it the irregular shape. C1: A line of 5 or 6 very small craters were in a line from the SE to the NW within the crater. Couldn't see the central peak of Hell. |
IWLOP #081 - Maginus

Maurolycus and Barocius both had terraced walls. Especially visible were the SE sides that seemed steeper than the other sides. Maurolycus had a central peak plus at least 4 very small craters within. There is a flat area in the SW that may be the remnant of a crater it impacted (???). Barocius looked like a rabbit’s face. Almond-shaped face with 2 ears – craters B & C. The floor didn’t appear smooth. The northern rim of C seemed very shallow. The rim of B seems very shallow as if it is disappearing after its impact.
Craters: Barocius, Maurolycus

Gemini was seen in the western sky with Castor and Pollux easily identifiable. By using the 10 mm eyepiece, I was able to distinguish between Castor A and Castor B. Castor C was not seen. Quite exciting to see two stars of the sextuplet.
Leo + M44
Time: Not recorded
Equipment: Telescope
S&T Chart Reference: 24
Leo was visible well above our tree line. I used the imaginary line from Chertan (θ Leonis) to η Leonis, then went the same distance toward Ascellus Australis in Cancer. About 2º from there was the fuzzy M44.
Large basin with flooded dark floor that can new seen with binoculars whenever this area is sunlit.

Observation 2 - August 31, 2020: C1: Seeing the 230 km Rimae Grimaldi was a "woo-hoo" moment. With the lighting on the Moon and the magnification, the 'valley' was readily seen. It was nestled between Grimaldi's eastern wall and the ridge formed as part of the southern Damoiseau. The ridge extended further south. |
IWLOP L8 (Libration Object): Bailly
This is the largest crater visible on the near side of the Moon and, with some libration, its entire surface can be seen.

No wind. No clouds. Jerry set up the 10” Meade SCT while I attempted to identify items on my observe list – potentially 13 items, depending on where light & terminator were located. Because the SW limb was librated, I was able to find Bailly.
C1: Because it was on the terminator, it appeared very elongated. One of its walls was on the terminator but features within its crater walls were quite easily seen.
C2: At least 7 craters on the floor or on its walls. It was difficult to determine if the walls were ridged or whether the floor looked rough near the walls.
This session was devoted to lunar observing. Three IWLOP objects were viewed.

No wind or clouds. Jerry set up the telescope for me then I began looking for things on my observe list - 13 items, depending on where light and the terminator were located. I found Grimaldi (on the list) and then had 3 surprises due to the SW limb being librated - Bailly, Cassatas and Klaproth.
Bailly Cassatas and Klaproth |
Grimaldi This was the first time viewing this crater. Grimaldi's west wall was on the terminator. The almost lace-like Damoiseau was to the east with Sirsalis and Sirsalis A to the S-SE. Appeared to be doors on the very dark floor. Refer to IWLOP #134 - Grimaldi for details. |

R1: Klaproth is larger and relatively smooth floor. Casatus had 2 craters (C and J) that were easily seen. Could also see A (on the wall or very close to it), H, G and H. The latter two are shallow and no high walls seen. Note: This was a surprise discovery. Looks a bit like Sirsalis/Sirsalis A. Casatus appeared to have a small dorsa or other structure in its western floor. |
IWLOP #083 - Rupes Recta
The famous "Straight Wall" is one of the most interesting features on the Moon.
Location: 22.0 S 7.0 W Origin: Tectonic Length: 110 km Rukl: 54 Type: Scarp
Objects: Rupes Recta, Birt, Promontorium Taenarium, Birt A, Rima Birt
Others Identified: Nicollet, Thebit, Thebit A
Observation 1: Variable high clouds. R1: The Straight wall was barely visible.R2: The crater Birt in Mare Nubium to the west was easily identified. R3: Promontorium Taenarium was very large - 1/4 as long and almost as long (east to west) as the Wall. The curve of the peaks made it look like a wall of a much larger crater (now gone). |
Observation 2: C1: Birt and Birt A were easily identified adjacent to the Wall. The shadow extended just west of Birt almost perfectly parallel to the Wall. Because this part was near the terminator, I could see the worn down crater wall (refer to note). Rimae Birt ran parallel to the Wall, running north of Birt; it was about half the length of the Wall. NOTE: (July 4/21) It always strikes me that there had been a large crater in this section of Mare Nubium because of the hint of a circular wall in the Mare floor. |

No wind, no clouds. The Moon was in the middle of the Winter Circle.
There were numerous IWLOP targets found that despite the beautiful temperatures I made rough sketches of the objects at the eyepiece, wrote notes regarding the required (or challenged) IWLOP observations, did rough sketches then completed the details later. I also noted some craters not required to view along with the targets. I tried using a x2 Barlow with some success but the x3 Barlow was too fuzzy/grainy.
Time: 10:10 PM ADT
The first target was IWLOP #52 - Montes Haemus and the Mare Serenitatis Lacus Group. The Lacus Group in particular was very interesting give the number in
Time 10:29 PM ADT
The second targets were Aristoteles, Eudoxus, Rima Ariadaeus, and IWLOP #48 - Aristoteles & Eudoxus. It was very interesting to compare these two craters for size, depth and features.
Time 10:38 PM ADT
Temperature: 9º C
SQM: 19.25
Completed IWLOP #41 - Mare Serenitatis. The numerous dorsa on the mare floor were intriguing and at times a challenge to find.
Time 11:21 PM ADT
Equipment: 10" Meade SCT, 10 mm eyepiece + x2 Barlow
Magnification: x1060
Completed IWLOP #33 - Posidonius. The crater floor with its roughness and numerous rime made this an interesting find.
Time 11:30 PM ADT
Completed IWLOP #53 - Rima Ariadaeus. The fact that it cut across mountains, ghost craters and through ridges with craters was intriguing. I wondered what had created such a long rift across the Moon's surface (but didn't investigate any further.
Time 11:45 PM ADT
Completed IWLOP #56 - Dorsa von Cotta & Dorsum Buckland. In searching this area of Mare Serenitatis, I found not find the feature named Rimae Sulpicius Gallus. However, if I ever own a dog again, I'd love to name it "Sulpicius" - 'Sully' for short.
Time 11:52 PM ADT
Temperature: -1º C
SQM: 19.32
Completed IWLOP #65 - Hipparchus. The ghost craters on its floor and its somewhat square shape were interesting.
IWLOP #033 – Posidonius
Flooded crater from the Upper Imbrian Era. The interior ring is higher than the lunar mean surface in the eastern portion. It has very irregular terrain. There are 5 separate rimae within Posidonius; these possibly happen when a large impact occurs on the edge of an already fractured basin.
Location: 31.8 N 29.9 E Origin: Impact Size: 95 km Rukl: 14 Type: Complex Crater (CC)

R1: Posidonius had one large hill on its floor along with what appeared to be ridges or smaller hills. Round and deep Posidonius A was just west of centre.
R2: Chacronac appeared shallow compared to Posidonius. Its NW crater wall appears non-existent except for Posidonius' crater ridge.
C1: I found two of the rimae within Posidonius, one running NW to SW and one running NE to SW.
C2: Chacornac A is almost centred in the crater. Very small and shallow. Had to stare for a period of time before it appeared.
IWLOP #041 – Mare Serenitatis
Nectarian Era impact basin predating Mare Imbrium, filled with Imbrium Era mare material, very titanium rich. It is rich in dorsa and rimae. The second strongest subsurface Mass Concentration (or Mascon) on the near side is centred under the Mare Serenitatis.

R1: Dorsa Smirnov and Dorsa Lister form a partial semi-circle that extended to Bessel and to its north. The structure formed by Dorsa Lister almost looks like a 'ghost crater'.
R2: The area surrounding the Dorsa Aldrovandi from Mons Argaeus to Posidonius and the crater Le Monnier is darker than that of the adjacent mare floor. Its also dark south of Dorsa Lister.
C1: The crater Very appears as a bright spot in the north end of Dorsa Smirnov. Very appears to be on the wall of a 'ghost' crater to its north and is also a darkened area.
C2: Dorsa Nicol heads northward and is perpendicular to the dark area of Rimae Plinius, terminating at Dorsa Lister. Dorsa Azara has a curve NW to SE.
IWLOP #048 - Aristoteles & Eudoxus
Spectacular pair of craters located at the edge of Mare Frigoris, the "Sea of Cold." These two prominent craters can be easily identified using binoculars.
Location: 50.2 N 17.4 E Origin: Impact Size: 87 km (Aristoteles), 70 km (Eudoxus) Rukl: 5, 13 Type: Complex Crater (CC)

R1: East wall of Aristoteles was especially terraced. Could see a circular pattern near the shadows on the west wall.
R2: Eudoxus is a deep crater with steeply terraced walls and a central peak.
R3: Aristoteles crater walls are not as tall as those of Eudoxus and its floor was smooth. Eudoxus had steeper walls and showed rises in the floor and small craters; its ejecta field is also smaller. In comparison, Tycho is higher-sided and has a much larger ejecta field and rays.
R4: Egede looked diamond-shaped and well flooded. Mitchell was quite shallow and its west wall impacted by Aristoteles. Galle was north of Aristoteles in Mare Frigoris and appeared quite shallow.
C1: The 2 peaks in Aristoteles were observed; the multiple central uplifts in the floor of Eudoxus were noticed.
C2: The 4 secondary craters were located. Sheepshanks and the much smaller Sheepshanks C were north across Mare Frigoris from Aristoteles. Mayer was just north of Sheepshanks. I looked west from Mayer to Kane and then NW from there to observe Arnold, a shallow elongated crater with an irregular north wall.
IWLOP #052 - Montes Haemus & Mare Serenitatis Lacus Group
Raised edge of Mare Serenitatis Basin, overlain with ejecta from the Mare Imbrium and flooded by basaltic lavas. These Upper Imbrium age lowlands near Mare Serenitatis are separated into multiple Lacus or "Lakes."
Location: 17.0 N 13.0 E Origin: Impact & Volcanic Size: 400 km (Montes Haemus) Rukl: 23,22 Type: Mount and Lacus

R1: Montes Haemus has a linear nature to its structure - very straight, almost like a box bottom. The high massif NW of Menelaus appears as part of a short strip along the mare shore.
R2: All 6 lakes (lacus) were easily seen between Montes Haemus and Manilius.
NOTE #1: The west ridge of Manilius was well illuminated, showing ridges on crater wall. 'Ghost crater' to the SE was well filled and joined Boscovich's NW wall.
Observation 2:
The sketch below was drawn April 19, 2021 while observing Manilius (IWLOP #059 - Manilius). What a difference 2 years makes!
IWLOP #053 - Rima Ariadaeus
Wide, prominent rima. Exceptional object when close to the terminator. It is a classic graben formed by separation of the lunar surface and down-dropping of material. This rima has a very notable fault structure apparent in its make-up. It consists of a series of offset segments and at least one offset may well be visible.
Location: 7.0 N 13.0 E Origin: Tectonic Size: 220 km Rukl: 34 Type: Rill

R1: Rima Ariadaeus cuts across mountainous features, across a ghost crater above Silberschlag and through ridges with small craters.
R2: The southeast wall of Julius Caesar is eroded. The floor looks filled as part of it is dark similar to there floor.
R3: Rima Ariadaeus and Rime Hyginus appear to form two mountain valleys going into Mare Vaporum. It appears that Rimae Trienecker forms the west rim of the valley 'delta'.

R2: The east and SE walls of Julius Caesar were non-existent. There was a line of craters across the east from SE to NW; small craters on the NW wall.
R3: Rimae Ariadaeus and Rima Hyginus quite visible.
Found the crater Ariadaeus just south of the end of the Rima on the shore of Mare Tranquilitatis. Sosigenes visible. Sinus Honoris is NE of Julius Caesar with a ridged area between them.
IWLOP #055 - Abenezra & Azophi
Two craters that are part of a group that is useful for orientation in this heavily bombarded area of the lunar surface.
Location: 22.0 S 12.0 E Origin: Impact Size: 43 (Abenezra), 48 km (Azophi) Rukl: 56 Type: CC
Objects: Apianus, Playfair, Azophi, Abenezra, Geber, Almanon
Others Identified : Andel, Catharina, Cyrillus, Theophilus, Kruzenstern
Observation 1: R1: Abenezra and Azophi are two overlapping craters between Almanon and Geber in the north and Apianus and Playfair in the south. C1: Abenezra overlaps both Azophi and Crater C. However, unable to tell the difference in their floors during this session. Observation 2: C1: Abenezra had a ridged floor whereas Azophi was smooth except for the small craters. Note: I attached my iPhone with x1.7 digital zoom part way through this session codetermine if would help by "zooming in". |
IWLOP #056 - Dorsum von Cotta & Dorsum Buckland
Prominent wrinkle ridges at the southeastern edge of Mare Serenitatis caused by subsidence.
Location: 24.0 N 12.0 E Origin: Tectonic Size: 220 km (Dorsum von Cotta), 159 km (Dorsum Buckland) Rukl: 23 Type: Wrinkle Ridges (WR)
Objects: Dorsum von Cotta, Dorsum Buckland, Sulpicious Galla, Menelaus, Dorsa Owen, Dorsa Gast, Rimae Menelaus
Others Identified : Bobillier, Linné, Tacquet
Location: Home R1: Sulpicious Gallus was located on the SW shore of Mare Serenitatis. Dorsum Buckland and Dorsum von Cotta were located north of the crater on the mare floor. C1: The shadows of Dorsa Owen and Dorsa Gast on the west shore of Mare Serenitatis were barely visible between the shore and Dorsum von Cotta. Rimae Menelaus could just be seen - Menelaus to the east and Tacquet in the west. Rimae Sulpicius Gallus not seen in this observation session. Note: Linné at top of Dorsa von Cotta appeared as a white circular fuzz; could not see the crater. |
IWLOP #065 - Hipparchus
A pre-Nectarian crater with badly disintegrated walls and square-like shape, perhaps due to pre-existing faults.
Location: 5.5 S 4.8 E Origin: Impact Size: 150 km Rukl: 44, 45 Type: Complex Crater (CC)

Spent most of this evening observing objects in the RASC IWLOP. Some of the objects were also included in the RASC ETM(T) observing program as well.
Sketch from IWLOP #053: Rima Ariadaeus |
Julius Caesar was viewed with the 10” Meade SCT at x250 magnification at 10:40 PM. Could see the E-SE wall was eroded or non-existent. It looked like the floor was filled/flat but wasn’t sure. Will require another look. |
Hipparchus was viewed at 11:52 PM. It had smooth floors except for the two ghost craters and craters X and N, the latter being slightly off-centre. It also looked like there was an opening in the NW towards Sinus Medii. The crater Horrocks was inside the crater in the N-NE and had a dark floor in shadow; Halley looked to have impacted/affected the SE rim. |

No wind, high cloud slowly moving over the Moon. On our return from a family BBQ and bonfire in Middle Sackville, we noticed the clear sky and Moon to the W/SW, still high enough to observe. Set up the telescope in the backyard.
After locating Langrenus and Vendelinus (x120 mag), I used my “new to me” x3 Barlow, then my x2 Barlow. The visible SE limb was awash with illumination so couldn’t see/identify any craters. Closer to the terminator was easier but seeing/transparency reduced the ability to observe features of craters beyond shadows. Disappointment! There was Earthshine this evening naked eye. Clouds rolled in so packed up. |

Jerry and I were invited to the Hamilton home for an overnight observing session. Given their clear skies and incredible horizon, we accepted their invitation.
Zodiacal Light
We watched the Sun set and saw the Zodiacal Light (ZL) rise on the western horizon. Beautiful! In the Atacama, Mars was centred in the base of the ZL but in Litchfield it was east of the ZL.
Mars
Time: 7:15 PM - 1:00 AM ADT
Equipment: Visual + Binoculars
Mars was first sighted SW of Aldebaran and south of the Pleiades. Although the relative placements of the stars and planet remained consistent, it was amazing to see how far the planet had 'travelled' during this session - approximately 30º - 40º to the NW horizon. WOW.
Satellite (ISS)
Time: ~ 9:08 PM ADT
Equipment: Visual + Binoculars
Noticed the ISS travelling towards us. The path was from above Aldabaran, above the Pleiades, over Cassiopeia, and then disappeared to the left and below the handle of the Big Dipper. Very bright throughout its entire path. Could see a sort of diamond shape through the binoculars, but could not clearly see the 'wings'.

R1: Mare Undarum ("Sea of Waves"), a wishbone-shaped area with two main sections, was seen in the libration. Sketched the area in IWLOP L2: Mare Marginus (see below).
R2: Mare Spumans ("Foaming Sea") is easily located south of Mare Undarum.
R3: Sinus Successus ("Bay of Success") is located adjacent to Mare Spumans.
C1: Condorcet is above Mare Spumans. Firmicus is adjacent to Mare Undarum. Apollonius located half way between Firmicus and Sinus Successus.
NOTE: Initially, I thought Sinus Successus was Mare Fecunditatis until I looked more closely at the shape and identified it using the S&T Moon Map.
IWLOP #003 – Mare Anguis
Small mare patch north of Mare Crisium that has less well-defined borders, and is a small mare section of one of the concentric rings from the Crisium impact. This area of the Moon is quite spectacular when observed just after Full Moon, particularly during favourable libration. It can also be viewed during the waxing crescent phase and while observing this are note the spectacular walls of Mare Crisium that are visible nearby.

IWLOP #095 - Copernicus
A prominent crater that is the prototype of the Copernican geological period. Copernicus features spectacular central peaks and is surrounded by both a prominent ejecta blanket and numerous secondary craters. The impact that formed Copernicus occurred about one billion years ago. It is easily visible in binoculars, particularly when near the terminator, and is by far the most prominent feature in the otherwise mostly flat Mare Insularum.
Location: 9.7 N 20.0 W Origin: Impact Size: 93 km. Rukl: 31 Type: Complex Crater (CC)
Objects: Copernicus, Kepler, Tycho
Others Identified: Fauth, Guy-Lussac

R2: The Copernican rays extend half way into Mare Imbrium, eastward into Mare Vaporum via Sinus Aestuum, NW through Montes Carpatus to Aristarchus. They overlap Kepler in the west.
C1: Did not complete this challenge in either observing session 1 or 2.
C2: Copernicus has a large number of shorter, overlapping rays, leaving the impression of a squashed tarantula. Whereas Copernicus' rays extend over the NW quadrant of the Moon, Tycho's rays extend over most of this side of the Moon, from the SW limb, NW to Mare Cognitum, Down to Mare Australe, NE into Mare Serenitatis, E to Mare Nectaris and Asperitatis. In essence, Tycho's rays cover a little over half the surface we see.
Observation 2: R1: Copernicus and Montes Carpatus were well lit near the terminator. The Copernican floor had 2 peaks centrally located. Floor and walls very well illuminated. Could see ridges on the west wall and highlights of tall ridges on the east rim. |

RI: Seeing the chain of craters caught my eye. Zucchius, Bettinus and Kircher were easily found adjacent to Bailly.
R2: Segner looked to share a common rim or ridge with Zucchius, and that Wilson shared a common rim or ridge with Kircher.
Note: I first saw these 3 craters two years earlier when they were on the lunar terminator. Refer to the RASC Explore the Moon (Telescope) - July 31, 2017 for details.

Transparency: Very Good (2)
Observation 1:
RI: The foreshortening makes the craters appear elongated, oval shape.
R2: Foucault is closer to Harpalus than is Bouguer.
C1: There is a common wall between Babbage and Pythagoras. J. Herschel was a large crater on the shores of Mare Frigoris, SE of Pythagoras.
Observation 2:
R3: Bouguer A and B are deep and round but Bouguer appears deeper and steeper. One corner of Bouguer not completely symmetrical and rounded. There is also a little outcrop on the NE and is perhaps flatter in the SW.
R4: Pythagoras looked to have two peaks, one definitely larger than the other. They covered a large area of the crater floor.
C2: Did not see the central peaks in Pythagoras during the previous observation but did this time; however, I did not sketch them.
A crater that is very elongated, perhaps as a result of a very low-angle impact or the merging of two crater structures. The Schiller-Zucchius Basin is the remains of a very large, ancient impact.
Origin: Impact Diameter: 179 x 71 km Rukl: 71 Type: CC & Basin
Objects: Bayer, Phocylides, Rost, Schiller, Schiller-Zucchius Basin, Weigel, Zucchius

Equipment: 6” Sky-Watcher Dobsonian, 9.7 mm eyepiece
Magnification: x120
Seeing: Very Good (2)
Transparency: Very Good (2)
RI: Schiller's distinctive, long, fairy wide size was what caught my eye first thing.
R2: Bayer was a small oval-shaped crater in the NW. Rost and Weigel were in the SE. Weigel appeared as part of the SE shore/mountainous area of the Basin. Rost looked deeper than Weigel.
C1: The Schiller-Zucchiius Basin was similar in shade to the floor of the crater Schiller, and was relatively smooth except for the formations along its N and SW shores.
Phocylides is a prominent crater and crater Wargentin is a very interesting, unique flooded structure that is filled to its brim with lava.
Origin: Impact / Volcanic Diameter: 114 km, 84 km Rukl: 70 Type: SImple Crater/Complex Crater

Transparency: Very Good (2)
RI: Wargentin is narrow and dark-floored compared to Phocylides with it's rounder and steep sides.
R2: Nasmyth and Phocylides have similar shading and colour on their crater floors. Crater C appears shallow-sided and a little lighter in colour.
C1: Noggerath, in the east, has 3 or 4 craters on its W and SW sides.
Pre-Nectarian Era crater with subtle variations on its floor. Crater Schickard contains bright spots of high albedo and several secondary craters. Lacus Excelentiae, the "Lake of Excellence", lies near Schickard.
Origin: Impact & Volcanic Diameter: 227 km, 150 km Objects: Clausius, Drebbel, Inghirami, Lacus Excellentiae, Lee, Schickard, Vitello Location: Home |
RI: Located Schickard and identified at least 3 craters in the SW floor of the oblong crater.
R2: Found the Lacus Excellentiae between Schickard and Mare Humorum. The Lacus looked darker and was certainly bordered by numerous small craters.
R3: Clausius is on the W side of the Lacus Excellentiae.
R4: Lehman appeared to "drain" into Shickard. Maybe just dark(?)
C1: The crater Lee's sides are greatly eroded, especially those facing Mare Humorum. Vitello has what appears to be a large peak just off-centre on the E side, and has either a shadow or opening towards Mare Humorum.
IWLOP #086 - Tycho
One of the youngest craters on the Moon, Tycho is inconspicuous during most of the lunar day, but comes into its own at the Full Moon where its rays can be traced over much of the lunar surface. The Tycho impact may have occurred as recently as 100 million years ago!
Location: 43.3 S 11.2 W Origin: Impact Size: 85 km Rukl: 64 Type: Complex Crater (CC)
Objects: Tycho, Street, Pictet, Surveyor 7 landing, Sassiredes
Others Identified: Orontius, Saussure
Love this crater's show of ejecta on the Full Moon! Makes the Moon's surface look like a peeled orange!
Location: Home R1: Tycho had a very prominent central peak, steep walls and darker ejecta in the north and northwest. Street and Pictet are two craters that form part of what I term the "flower petals" surrounding Tycho. C1: Surveyor 7 landed a short distance north of Tycho's rim. Not exactly a smooth-looking surface in large quantities for the lander's landing. Sasserides, Saussure and Orontius were identified. There were numerous small unnamed craters as well. Note: Under certain light, Tycho looks like a flower centre with several small flower petal encircling it. Loe this crater's show of ejecta on the full Moon! |
IWLOP #096 - Mare Imbrium / Eratosthenes / Copernicus System
This area of the Moon illustrates the overall pages of the major systems. You can trace out the relative ages of each by noting which crater is overlain on the other.
Origin: Impact and Volcanic Size: Various Rukl: 19-22, 9-12, 31 Type: Various

NOTE: Archimedes appears shallower than Eratosthenes (based on shadows in their craters). Eratosthenes had taller/longer shadows on its floor and towards the terminator.
IWLOP: Note these features | My Observation |
Mare Imbrium lavas fill crater Archimedes; they are post-impact, but pre-Imbrium. | R1: The opening in the NE Archimedes wall allowed for the lava to fill the crater. |
The crater Eratosthenes is post-Mare Imbrium but pre-Copernican. | R2: In this session, a large shadow covered most of Copernicus' floor. |
The crater Copernicus is the most recent major impact in this area and overlies older structures. | R3: Copernicus and Montes Carpatus were located. |
The ejecta blanket surrounding Mare Imbrium is the oldest part of this system and dates back to the Imbrium impact itself. It is especially noticeable in some areas, e.g., in the area of the crater Julius Caesar (Rukl 34). | R4: Mountainous area on shores of Mare Imbrium evidence of ejecta. |
IWLOP #106 - Sinus Iridum
Massive, spectacular, flooded crater on the edge of Mare Imbrium. It combines the high mountains of Montes Jura with a missing southeastern rim & two prominent “capes.” Sinus Iridum covers more than 10 degrees of the lunar surface and may require various terminator angles for optimum views of all the features listed.

R1: Montes Jura is a half circle structure on the north shore of Sinus Iridum, light in colour compared to the Mare floor. The crater Bianchini impacted the crest of its northern wall. R2: Both Promontoria LaPlace and Heraclides appear steep sided and rugged, projecting into Mare Imbrium at both the eastern and western tips of Montes Jura respectively. R3: Helicon and le Verrier craters are aligned and point to Promontorium Heraclides. The crater C. herschel is to the SW of this promontorium. |
C1: Sharp and Mairan appear as deep oval craters versus the irregular shape of Maupertius. The latter may be misshapen perhaps because of many previous impacts filling it in (?).
C2: The Luna 17 landing site is south of Sharp and SW of the Promontorium Heraclides on the seemingly flat Mare Imbrium.

Saw the Moon during my walk from 2:30 PM – 4:30 PM so decided it would be a good evening for observation. I was also interested in completing one or two items in the IWLOP. I included my rough sketch of “Huggins, Nasireddin & Miller” in my ETM logbook; a detailed sketch is in IWLOP #72. Also observed Saussure, Proctor, Orontius, and Walther but didn’t draw them in detail. I then looked at the area around Mare Vaporum. |

This observation was two days after First Quarter.
R1: Located the full range of the Montes Apenninus that forms the southern Imbrium basin. C1: I located and sketched the northern portion of the mountain range that contained Mons Hadley, Mons Hadley Delta, and Mons Bradley. However, Mons Huygens, Mons Ampère, and Mons Wolf were also located and identified in the southern range. |
NOTES: (from a web search re definition of "Apennine Bench"):
"The term Apennine Bench Formation (ABF) was originally used to denote the diamond-shaped zone of relatively smooth, flat light-gray material that has high albedo (reflectance) situated roughly midway between Montes Apenninus and Archimedes and is somewhat larger than Archimedes in size. It has a unique "KREEPy" chemical signature. The acronym ‘KREEP’ is used to identify higher abundances of potassium (K), rare earth elements (REE), and phosphorus (P). By relative dating, we can tell that the ABF formed after the Imbrium basin impact event (around 3.85 billion years ago)and before Mare Imbrium – the massive lava deposit that erupted within the basin, filling it to about half its original depth. This stratigraphy (time order) tells us that the ABF could be an example of pre-mare volcanism, whose magma came from a different source than the later basaltic eruptions that cover about 30% of the nearside. Since its formation, the ABF has been modified by many impact craters."
IWLOP #072 - Huggins, Nasireddin & Miller
A fine trio featuring nearly equal sizes and structures; located in a rich area of many craters.

R1: Found the central peaks for all three craters. Nasireddin appears to have impacted on Miller and Huggins, and Huggins has impacted on Orontius. The much larger Orontius was located to their west and had craters on both its rim and floor.
R2: Found Saussure a short distance from Orontius. Proctor was 2-3 times that distance from Saussure and was quite shallow.
IWLOP #078 - Archimedes & Montes Archimedes
Crater Archimedes is an impact structure that was flooded from the interior by Imbrian Age lava. Montes Archimedes is a notable mountainous area just south of Archimedes.
Location: 26.0 N 5.0 W Origin: Impact Size: 140 km Rukl: 22 Type: Flooded crater and basin remnant.

Seeing and visibility were very poor with high cloud/haze obliterating many stars. The Moonset was around 10:15 PM the previous evening so was not a factor.
Hyades / Melotte 25 / Caldwell 42 / Collinder 50 A very hazy sky. Only the brightest stars were seen naked eye, and with binoculars I could barely make out the Hyades star field. I found Aldebaran using Orion's Belt stars as the pointer. With the binoculars, I easily found σ1 and σ2 plus θ1 and θ2. I sketched the star field as seen in my binoculars. The shaded area signifies the open cluster Hyades. θ1 was at 1 o'clock to θ2 at this hour of the morning. I noted the magnitudes of the identified stars once back in the house, especially since many of them were variables or variable doubles. |
|
M47 / NGC 2422 In between the observation of Taurus θ1 and θ2, I attempted to look for M47. According to SkySafariPro, it should have formed a triangle with Procyon and Sirius. However, the haze meant M47 was nowhere to be found nor were any stars in the constellation Puppis. I will have to wait for better seeing and transparency - and use a telescope! My 6" Dob or 10" Meade SCT should do the trick. |
This session was devoted to lunar observing. IWLOP objects were completed and Mars and Saturn were observed.

My main objective was to check off more items from the RASC Explore the Moon (Telescope). In doing so, it meant I cold also observe several IWLOP objects:
I also took some time to locate two planets:
Saturn Viewed Saturn west of the Moon in the southern sky. Able to see the planet and one of its moons (Titan). The rings were clearly visible as well. |
|
Mars Visually, Mars twinkled slightly. Using the telescope with the x2 Barlow with seeing that was not the greatest meant I had a blurred view of the planet. However, I catch sight of the northern polar cap occasionally. |
IWLOP #068 - Montes Alpes & Vallis Alpes
Spectacular boundary of the Mare Imbrium Basin, with heights from 1.8 to 2.4 km ranging up to 3.6 for the great Mont Blanc. The impressive Vallis Alpes runs perpendicular to the prominent Montes Alpes, making this one of the most picturesque areas of the Moon. The valley is a wide rift valley, 180 km in length that links Mare Frigoris to Mare Imbrium.

R1: The ejects blanket of Aristillus rays out from its high crater sides. Autolycus doesn't appear to have ejecta to the same degree and is shallower than Aristillus. C1: Very small secondary craters (A, B, C, D) were located near Aristillus and appeared to be located along the ejecta lines / rays. |
IWLOP #071 - Walther
Large, prominent Nectarian Era Crater.
Location: 33.0 S 0.7E Origin: Impact Size: 132 km Rukl: 65 Type: Complex Crater (CC)
Objects: Walther, Nonius
Others Identified: Alpetragius, Alphonsus, Ammonius, Aristillus, Arzachel, Autolychus, Herschel, Luna 2 landing site, Ptolemaeus, Sinus Lunicus, Thebit
Observation 1: R1: Walther had terraced walls, especially in the north-northeast. There were five peaks / bright areas seen off-centre towards the east side. Several others interrupted the exterior walls; not all were sketched. C1: Shortly after sunset, a lightened area stretched across Walther from the east to the overlapping craters. |
Observation 2: R2: Details of the numerous craters and the central peak were more readily seen with the larger telescope and magnification. |
IWLOP #073 - Regiomontanus & Purbach
Regiomontanus is a pre-Nectarian Era crater. Note it's severely eroded walls and elongated shape. Purbach is a prominent pre-Nectarian Era crater with a poorly defined and eroded western wall.
Location: 28.4 S 1.0 W Origin: Impact Size: 126x110 km (Regiomontanus), 118 km (Purbach) Rukl: 55 Type: Complex Craters (CC)
Objects: Regiomontanus, Purbach
|
Observation 1: R1: Regiomontanus was located north of Walther. Regiomontanus A was located on its north floor. At x120 magnification, the centre peak was a little off-centre and a few crater-like formations comprised the terrain of that area. Regiomontanus appeared lower in elevation than did Walther. |
Observation 2: The line of craters on Purbach's floor is what caught my attention, in combination with the line of craters in Regiomontanus. NOTE: The shadows that showed like two lines going from near the rim to almost the centre in the previous observation may have been the east and west walls of the craters on the floor. R2: Purbach's north wall was either terraced quite well or was slumped (?). Crater G was completely in shadow on its floor; its impact on Purbach's north wall was substantial. Tonight there appeared to be 2 shallow craters in a line southward from G above crater W; small crater A was below and in line with them. Two craters (U and S) impacted the south wall. Didn't see this detail in 2018. |
IWLOP #074 - Arzachel
Arzachel is a spectacular Imbrian Era crater with sharply defined, deep-terraced walls. It makes a nice trio with Alphonsus and Ptolemaeus to the north.
Location: 18.2 S 1.9 W Origin: Impact Size: 97 km Rukl: 55 Type: Complex Crater (CC)

R1: Arzachel had an off-centre peak, broad wall, and two valleys in shadow. The depression valleys E and F on the southeastern and southwestern walls were in the shadows and not easily seen, even at this magnification.
R2: Alpetragius had its crater floor seemingly filled with a volcano-looking peak.
R3: Thebit and Thebit A were to the southwest of Arzachel. The smaller Thebit A had impacted near Thebit's NW rim.
C1: The low hills on the south and southwest floor of Arzachel were observed.
C2: The accurate rille was noticed because its shadow was darker than the shadow cast from the rim onto the crater floor.
IWLOP #075 - Ptolemaeus & Alphonsus
Very prominent craters easily visible through binoculars. Older Ptolemaeus (pre-Nectarian) and younger Alphonsus (Nectarian) are visible on the terminator at the same time. Ammonius, located on Ptolemaeus' floor, is one of only a few named craters within a larger one.
Location: 12.0 S 2.0 W Origin: Impact Size: 153 km (Ptolemaeus), 110 km (Alphonsus) Rukl: 44 Type: Complex Craters (CC)
Objects: Ptolemaeus, Alphonsus, Herschel, Ammonius, Flammarion, Rima Flammarion
Identified Others: Glyden, Mosting, Mosting A, Spörer
Observation 1: R1: Alphonsus' central peak was located adjacent to a rise or rille. |
Observation 2: R1: Herschel is north of Ptolemaeus and is quite deep by comparison, and is especially deeper than the shallow Spörer to its north. C1: There are three distinct dark patches in the NE, SW and SE. NOTE: Research conducted after this session indicated the dark patches were ash deposits from fire fountains that ocurred after Alphonsus was formed. |

No wind or cloud. Although moonset wasn’t until near midnight, the Moon disappeared from our view by 9:30 PM due to our southerly treeline. I knew I had a limited window to see the Moon before it disappeared. My focus was on the NE portion, especially Montes Caucasus. Identified Calippus and noted 3 small volcanic-looking cones SE of the range. Also noted a line of brightness in the floor of Mare Serenitatis; identified it as Dorsa Smirnov. |

A group of RASC Halifax Centre volunteer were on the Halifax waterfront at Bishop's Landing. We were participating in the RASC's 150th anniversary cross-Canada star party. We had over 200 people come visit the numerous telescopes set up on the board walk and despite being downtown Halifax we were able to sow visitors Jupiter and other objects easily seen through the urban light pollution. It was a warm night, no breeze or clouds. Through the telescope, the stripes on the planet appeared diagonal to the horizon. I sketched Jupiter with its moons before it disappeared behind one of the buildings. Ganymede, Callisto and Europa formed a triangle on one side of the planet and Io was alone on the other.

This was the second year we camped at this location with Dave and Christine where we have our "private" star party.
No wind. No dew. The Lake was dead calm which allowed for the perfect reflection of the stars. No clouds but the horizon to the north was certainly better than to the S and SW; it did improve as the evening progressed.
Milky Way
Time: 8:00 PM - 4:16 AM ADT
Equipment: Visual + Binoculars
Just wanted to highlight a segment of this observing session to the Milky Way. It was seen as a faint nebulosity across the sky around 8 PM and by 4 AM the Great Rift was clearly defined all the way from Cygnus through Vulpecula to Aquila that was now setting. A row of very bright stars seemed to be falling down through the Rift but I did not identify what they were.
Observation Time 1:
Ophiuchus + Serpens Caput + Serpens Cauda Ophiuchus: I located the stars of this huge constellation above Scorpius, this protector of Hercules. Easily saw the curve formed by Nehushtan, Sabik (η), ζ, Yed Posterior (ε) and Yed Prior (δ). Looked above this to find Rasalhague (α), Cebalrai (β), Marfik (δ) and κ. Serpens: I then went eastward from Yed Prior to follow the stars comprising the constellation Serpens Caput (the head of the snake). Going to the other side of Ophiuchus, I went westward and followed the stars from nu Ophi to Alta (theta) - the snake's tail. Once identified, I pointed out all 3 constellations to Jerry and explained how Ophiuchus was the snake charmer. |
|

|
Jupiter Readily located visually. Used my binoculars to view 3 of the 4 Galilean moons - Europa, Ganymede and Callisto. |
||
M8 (Lagoon Nebula) + M20 (Trifid Nebula) Attempted to see M8 visually but that was not possible. However, it was easily located and viewed with my binoculars. The oval-looking nebula and about 5 bright stars were readily identified. In the same FOV was M20. I did not view it more closely to determine if there was any "structure to the cluster. |
Keystone of Hercules + M13 (Hercules Globular Cluster) Sometime after 9:00 PM, I noticed the Keystone overhead so pointed my binoculars at η Herculis and saw M13 as a grey fuzzy. Could not see the specific structure of the globular cluster. |
||
International Space Station (ISS) The ISS came into view visually as I looked up at Corona Borealis. Very bright and easy to follow so used my binoculars. I could actually see two distinct wing structures. 1 = first sighting of ISS |
|
||
Sagitta I had attempted to find this last evening but had failed. Tonight, however, after some effort, I did find all 4 stars. Yay!
|
Pisces Austrinus Fomalhaut was the star that brought my attention to this area of the sky. It was about 5º above the SE horizon and was very bright in the evening sky. All 10 stars of the constellation were easily seen visually; I did not use my binoculars. |
Observation Time 2:
Taurus Had to wait until 4 AM for Taurus to rise above the tree line. θ1 and θ2 appeared one above the other, pointing towards 11:30 o'clock. |
Auriga I located Auriga by first locating Capella, then identified the major stars of the constellation. I began to "Messier hop" beginning with the "Leaping Minnow," an informal grouping of stars that includes 14, 16, 17 and 19 Aurigae. I then found the grey fuzzies of M38, M36, then M37. Comet 21P/Giacobini-Zinner appeared as a vertical smudge west of M37. In binoculars, there was no distinction between the comet and its tail. However, Dave had a small telescope with him on the beach through which the distinction could be made. |

M11 (Wild Duck Cluster)
Time: 4:40 AM
Equipment: Visual + Binoculars
S&T Chart Reference: 67
The Milky Way was so b right, its central dark lane was clearly discern le. I knew that M11 was located near Scutum and the semi-circle of stars beside it. I visually located the star cloud then found the small grey fuzzy adjacent to the golf club head with my binoculars. Dave also had a view of it in his telescope.
Gemini + M35 |
Orion + M42 (Orion Nebula) + M43 (De Mairan's Nebula / NGC 1982) Time: 4:52 AM Equipment: Visual + Binoculars S&T Chart Reference: 14, 16 B I first noticed this constellation was once again visible after locating theta1 and theta2 in Taurus. What a pleasant sight! The big was so clear that all the stars ere brilliant and the nebulosity in the sword (M42 and M43) was quite clear visually and with binoculars. |

Light breeze. Occasional cloud in various parts of the sky all evening. Very loud crickets this evening. Peter & Ilias Hurley, Jerry Black, and several others were there.
Jupiter (in Libra) I could not locate all 4 moons. Could only locate 1 this evening that I assumed was Callisto. |
|
M7 (Ptolemy's Cluster) I specifically sought this out as I hadn't observed it in a while. Visually, could make out a grouping of stars lower to the west of the Teapot. The large open cluster filled my FOV with numerous stars clearly visible. |
|
Stars of Ursa Major I was showing Ilias and Peter the night sky later in the evening. Using my telescope, we first viewed the optical double Mizar and Alcor in Ursa Major. Used the handle of the Big Dipper to locate Mizar then enjoyed the view in the eyepiece. Mizar A was larger and brighter than Mizar B. Alcor was easily seen below Mizar in the telescope view. A triangle was formed by Mizar-Alcor-HD116789. A line of stars to the side of this triangle were identified:
|
|
M8 (Lagoon Nebula) I showed Ilias and Peter two views of the Lagoon Nebula: a) Binoculars: Used Kaus Australis and the Teapot spout to locate it. Saw M8 as an oblong nebulosity with a line of 4-5 bright stars with a couple more above it b) Telescope: Jerry showed us through the telescope. We could then see two parts to the object - a small nebulosity with a line of stars plus the adjacent denser nebulosity with numerous stars. Such a difference from the binocular view. |
|
M13 (Hercules Globular Cluster) I showed them the Keystone of Hercules almost directly overhead, then showed them how to find it 1/3 of the way between η Herculis and ζ Herculis. Success! They found the small grey fuzzy. |

M31 (Andromeda Galaxy)
Time: 11:15 PM ADT
Equipment: Visual + Binoculars + Telescope with 30 mm eyepiece
Magnification: binoculars x10, telescope x83
S&T Chart Reference: 3, 72
I explained how to find it using Cassiopeia and by using the Square of Pegasus/Andromeda. Could see it visually and then a much better view through binoculars. Jerry then showed us the view through the telescope where the bright centre of the oval galaxy was observed.

Clear skies to start then high thin clouds began to obscure the perfect views of craters.
Poncelet appeared to have little or no rim on the S and NE. Only a bit of shadow cast on its north and west rims. There was a shadow from a peak. Because of the angle of viewing, Pascal and Brianchon appeared to be joined. The SW edge was rougher compared to the others and a peak’s shadow was seen in both.
|
|
Grimaldi had a high side to the NW causing shadows towards Riccoli. To the SE rim, 3 shadows were cast (peaks?) along the rim.
Going away from the SE rim were 4 very small craters that led me to Sirsalis and Sirsalis A. There was a dark line SE of Sirsalis – Rimae Sirsalis.
In referencing the S&T Moon Map, I realized the bumpy terrain between Grimaldi and Sirsalis was Lacus Aestatis.
|
Schikard had 2 craters very visible in the SW limb. The NE rim had a rough area between it and Lehmann. Its floor was a little darker than its surroundings.
Wargentin had a crater off-centre that appeared to have a ridge running from rim to rim over or very close to the crater. The rim was more evident on the side of the Moon’s SW limb (not the terminator). To verify the rim, I observed it twice.
Phocylides had a large crater on its S-SW rim and its NE rim.
Nasmyth was barely discernible; its NE rim the only evidence that it was beside Phocylides and Wargentin.
Lacus Excellentiae was seen but couldn’t see Clausius.

C1: I was able to locate the secondary craters Sirsalis J, F, G and H.
Observation #3:
Date: August 30, 2020
C2: Finally locate the Rimae Darwin! It intersected Rimae Sirsalis that ran from Sirsalis/Sirsalis A south to the crater Darwin. It took a bit of time to see this but it was worth the time to adapt to the brightness to discern the rimae.

|
|
Observation 2: R2: Fontonelle and Philolaus located. Couldn't see them last week; probably a more favourable libration this evening. C3: I tried to view the 5 craters on Plato's floor; located one (refer to the sketch). I don't have a large aperture scope to view them but did try a couple of eyepieces to see these craters. No success in viewing the other 4. |
I was working on both the ETM (telescope version) but also spent time in general observing and on IWLOP objects. Also viewed Jupiter and its 4 visible moons.

Clear skies to start but clouds came in for about an hour around 10 PM then cleared off to a clear sky again. Because of the treeline at SCO on the driveway side of the Warm Room (best view of the Moon after Moonrise), I didn’t start observing until 12:02 AM. Wanted to find Apollo 12 & 14 landing sites but the iPhone App didn’t cite them. However, I did spend time on the shores of various maria – Cognito, Frigoris, Imbrium, Nubium, and Oceanus Procellarum.
Also of note was how heavily cratered the southern limb was. Didn’t attempt to identify them at this time as the craters on the maria and the related mountains caught my attention. Found 3 “new-to-me” features: Regiomontanus, Mons Pico, Bliss. Downside to the 3-hour observing session was that I didn’t fully explore the landing sites for Apollo 12, Apollo 14, and Ranger 7. Maybe tomorrow night/AM? |

Tried to locate Stadius but wasn’t successful. Contacted Dave Chapman as to how best locate Stadius. He described it as a “ghost crater”. It’s old and has been flooded by lava when the mare formed so its walls are not too high, and it has been eroded by impacts so it’s a bit camouflaged. The trick is to look for it when it’s near the terminator (tonight or early tomorrow AM?) when the low sun angle will cast it in a more obvious relief.

I had spent some time looking at the Moon to determine what features to observe. I managed to complete IWLOP #84 - Mons Pico & Montes Teneriffe in Mare Imbrium. Also observed some features needed for the Explore the Moon (telescope).
Jupiter (in Libra) Jupiter was quite bright although not as bright as Venus or Mars. Could easily see Callisto but Io took much looking to find it. There was a bulge on Jupiter's surface that could have been Ganymede or perhaps just a very bright spot that made it look like a bulge or moon. |
|
|
Saturn (In Sagittarius) Saturn was high in the sky above the Teapot's spout and M8. Very Bright. Was able to determine one moon - Titan. Initially I thought it was Phoebe but it wasn't far enough away from the planet to be so. Could not make out any moons closer. |
Satellite |
α Perseus Cluster |
M8 (Lagoon Nebula) Seeing M8 with a telescope is very different than through binoculars. What I had seen on September 3, 2016 was 5 or 6 bright stars in a dense clump that formed a line of stars and the less dense clumps filled the mottled brightness above it. The telescope view seemed to have 5 or 6 vertical rows of stars that remind me of the α Perseus Cluster. |
Meteor
Time: 1:30 AM
Equipment: Visual
A very bright meteor lasting 1.5 seconds. Began whitish and ended in bright green as it travelled through the region of Draco.
This was a night spent mostly on the ETM(Telescope version). The results of the lunar session can be found at Explore the Moon (Telescope) - August 29/30, 2018.

No clouds or wind. The crickets were surprisingly loud. The Branton's were visiting so showed them the double stars of Mizar-Alcor in the Big Dipper using binoculars.
At 11:23 PM, after they had left, I located the double using the telescope where I also saw Alcor's companion star HD116789.
This was a night spent mostly on the ETM. There were other observations made but they were more for my interest than for the purpose of an observing program.

12:07 AM: |
It was then I referred to the S&T Field Map of the Moon to identify craters. Took me about 15 minutes to orient myself to the upside-down and what I was seeing due to Moon phase. I noticed Apollo 17 on the map so decided to focus on that area. To get to Apollo 17, I located Le Monnier then navigated along the shores of Mare Serenitatis. The name of the landing site is the Taurus-Littrow Valley. Posidonius had 2 craters seemingly in its rim and another just outside. I drew what I saw then identified the following features: |
Coordinates for Apollo 17: |
Coordinates for Apollo 11” LRRR: 0.673445 N, 23.47307 E Lunar Module (LM): 0.67416 N, 23.47314 E |
1:10 AM: To get to Apollo 11, I went from Vitruvius to the craters Plinius to Ross and Maclean to Arago & Manners. Followed the curve formed by 2 small craters (Ritter and Sabine) to Moltke and the landing site. |
NOTE: Looked up the lunar coordinates for the two Apollo missions later.
1:29 AM:
SQM: 18.66. Temperature still at 18° C, no wind, no clouds but still a bit hazy. Decided to focus on the shorelines of Mare Nectaris where if found the craters:
I then headed north back to the Apollo 17 landing site, to the crater Daniell just above Posidonius, then on to Hercules and Atlas. Hercules was very visible, but Atlas was now mostly beyond the terminator.

Jerry and I were camping at Blomidon along with our two daughters and their families. I was able to show both our 5-year-old grandson and 2-year-old granddaughter a view of the Moon and Jupiter through the 6" Dobsonian we had brought with us. Our grandson particular was quite excited about identifying things he saw in the sky - naked eye and through the telescope, not to mention in SkySafariPro.
Jupiter, Mars & Saturn Our grandson pointed to Mars and asked what the name of that "star" was. When he was told it was actually the planet Mars, he was so excited! He ran to his parents shouting, "I saw the star Mars!" Jupiter was west of Mars and was bright enough to point it out to him. Also showed him Venus that was just about to set in the west; he was so excited to see his 3rd planet for the evening. I told him he had actually seen 4 planets and he correctly identified "Earth" as the fourth. Smart boy! |
Cassiopeia Red Moon. Red Sun. |
Big Dipper + Mizar A & B + Alcor Because our grandson had stars on his bedroom ceiling, he knew the Big Dipper when I pointed it out to him. I also told him the centre star in the handle was special because it was a double star. I showed him on SkySafariPro what it would look like close up then showed him through the eyepiece. Wow. |

Warm night. High fog and cloud impeded clear viewing of any object for any length of time. Dave Chapman arrived around 7:45 PM to collimate the telescope. He was unhappy with the attempt to do so at Kejimkujik, so came here to determine if it could be done. Success! Collimation achieved. He also brought his eyepieces, and we tried his Televue Ethos 8 MM. The clarity was wonderful!
After he left, I returned to my 25 mm eyepiece and between episodes of fog/cloud cover, drew the Sinus Iridum. What captured my attention was the brilliance of the face of the semi-circular Montes Jura. The pure white edge contrasted to the adjacent terrain. The shadows of the two promontories were evident. There were two faint craters to what would be the NE, one of which might have been Maupertuis or just the two smallest craters nearest Promontorium Laplace. Needs a further investigation. Did not look for other features due to limited time during sucker hole opening. Gave up at 9:50 PM. |

Saturn Time: 9:20 PM ADT Equipment: telescope + 25 mm eyepiece Magnification: x48 Saturn was in the SE sky above our neighbour's back shed. The telescope very clearly provided a view of Saturn and its rings. No ring separation but could see a gap between the planet and its ring structures. This view, however, did vary with the changing atmosphere. |
|
Ursa Major In all 3 eyepieces, Mizar was seen asa double star. As in 2016, there was a third star that formed a triangle with Mizar and Alcor; I later identified it as HD116798. Below HD 328226 was a line of 4 stars, ranging in magnitude of 11.1 - 13.6 (#1 - #4 in the sketch). The identified HD238226 and a fainter magnitude 12.9 star to its right as GAIA 1563780481323958784 (#5 in the sketch). Quite the handle! |
IWLOP #100 - Bullialdus

Observation 1: R1: The ejects blanket of Bullialdus is mostly to the SE, extending out to A and B.
|
Observation 2: Saw this again when observing Kies and Mercator (IWLOP 101). Walls were very terraced and had at least 2 central peaks. Rim is not rounded completely; perhaps the rim has collapsed partially in some sections (?). The north rim didn't look as defined as the others; not sure if due to crater formation or the lighting on the Moon. |

We were playing with my newly-acquired 6” Dobsonian (gifted to me after the Kejimkujik DSW). Aligned the finder scope with the tube and ‘pushed’ it to the Moon. It provided me an upside-down view of the Moon, but was able to identify Clavius, Porter, Rutherfurd and Blancanus, as well as other features.

The 78.6% Waxing Gibbous Moon was going to rise at 11:21 PM ADT. Jerry and I were just beginning to see a brightness in the east.
Teaspoon I had read about this on the RASC discussion list or in one of the RASC newsletters or magazines in the spring. This was the first time I actively looked for it. We were searching for Mars adjacent to Capricornus. With Sagittarius so high in the sky, I decided to look for the Teaspoon. There it was. We could easily see ρ1, 43, π, ο and ξ2. Did not have binoculars with us so couldn't look for the double star of 43, nor the binaries ρ1/ρ2 and ξ1/ξ2 Next time. |

No clouds and only a light breeze across the water. Hubby and I were viewing the 4 planets (Mars, Saturn, Jupiter, Venus) because of their alignment on the ecliptic - me visually and with binoculars, him with his camera. It was a quiet calm evening with the planets and Moon providing beautiful reflections in the Lake.
Venus (in Leo) Observation #1 @ 9:24 PM: Observation #2 @ 10:24 PM: |
Mars |
Saturn (in Sagittarius) On this night, Saturn was 3º - 4º above & NW of Kaus Borealis. I couldn't see the rings with the binoculars. Only saw the planet as slightly elongated in the middle latitudes. |
Jupiter (in Libra) Used my binoculars to view Jupiter's moons and its proximity to α Librae, approximately 10º. Could only see 2 of the 4 Galilean moons; I later identified them as Callisto and Ganymede. |
Meteor
|
M7 (Ptolemy's Cluster) Noticed a patch of bright light sky just west of Kaus Australis. Used binoculars to identify the cluster. It's a beautiful open cluster, site bright and filled my 6.5º FOV. Seven to eight of the brightest stars looked like they foreman "H" albeit an artistic one. |
Cygnus + Coathanger / Collinder 399 / Brocchi's Cluster Found Deneb then identified Cygnus aka the Northern Cross. Followed the line from Deneb to Sadr to ν to Albireo. Used my binoculars to locate the double star Albireo: I then put down my binoculars for a moment to visually locate Albireo and the possible location of the Coathanger. Put my binoculars up and there it was! All of the stars in the hanger and hook were visible. |
Teapot + Saturn Saturn was 3º - 4º above & NW of Kaus Borealis.
|
Scorpius All of Scorpius was well above the horizon; theta was at least 10º above the horizon if not a little more. Could see Antares in all of its redness quite well. Could also identify most of the stars in the stinger and all of the stars in the constellation above Antares except nu and rho. Always seem to have difficulty identifying / locating theses two. |
Meteor M5 / NGC 5904 Found M5 after locating Ophiuchus and Serpens Caput. Used the two stars δ Ophiuchus and μ Ophiuchus to find M5. Fairly faint fuzzy, but did see it and more readily using averted vision. |
Planets: Venus (in Leo)
Location: Rushing River Campground, Sleeping Giant Provincial Park, ON Clear skies and no cloud. We had our chairs on the Lake Superior shoreline within inches of the water. Mama duck and 7 ducklings swam past us within arm's reach - their fear of humans was not evident. Sitting on the narrow shore, we watched as the sun set over the Sleeping Giant and the stars begin to appear. A beautiful night on the shores of Lake Superior. |
Venus (in Leo)
Time: 10:45 PM CDT
Instrument: Visual
Venus was only about 7º above the western horizon, near Regulus in Leo. The planet was first located at 9:47 PM.

Light wind at this time of evening. The few clouds earlier in the evening have disappeared.
Earlier in the day when trying to set up camp, we had to open both flies of the tent to allow the wind to go through it during set it up (otherwise it became a kite) and weighed down the floor with camp gear to keep the tent from blowing off the mountain. Too windy for a camp stove so had a sandwich supper inside the tent.
Venus (in Virgo) Viewed Venus naked eye. Found it 15º above the WSW horizon below β Virgo (Zavijava). |
|
Jupiter (in Libra) Jupiter could easily be found visually in the SW sky. My binoculars allowed me to find all 4 Galilean moons - Io, Ganymede, Callisto and Europa. Jupiter was located less than 5º from α Librae at approximately 2 o'clock to the star. |
|
Scorpius Observation #1 @ 9:50 PM: Observation #2 @ 11:00 PM: |
|
M11 (Wild Duck Cluster) Looked for the semi-circle of stars above the Teapot and used binoculars to locate M11 (as the golf ball next to the golf club). Could make out the brighter centre with fading edges of the globular cluster. |
Summer Triangle (DAVe) |
Leo First noticed Regulus very low in the sky, about 5º above the horizon with Venus nearby. Could faintly make out Denebola and may have seen θ Leonis and δ Leonis, but not sure. Definitely didn't see his legs or most of his mane/head. |
Lyra
|
M8 (Lagoon Nebula) |
Ophiuchus The curved line of stars above Scorpius caught my eye. Very quickly located α, β and κ at the top of the huge figure, but only visually. Didn't look for the accompanying stars in Serpens Cauda and Serpens Caput. |
Cassiopeia |
|
Cygnus + Coathanger / Collinder 399 / Brocchi's Cluster Used the binoculars to view the double in Albireo. Could see the larger yellowish star β1 and the bluish companion albeit smaller β2. Also used Albireo to locate all 10 stars of the Coathanger. Within 10 minutes, the light and dark lanes of the Milky Way became visible. |

There was a very bright flash near Cygnus. It then moved left to right in my binocular FOV before disappearing.
Planet: Venus (in Leo)
Stars: 31 Leo
Occultation: Venus-Regulus
Location: Astotin Recreation Area in Elk Island National Park, AB Clear skies. Very little if any breeze or clouds. Had a suppertime visit from a former cohort and now a good friend, Mike Hoffman. It was great to reconnect and to explain this newfound interest to him. We encountered a few buffalo roadside during our travels throughout the park. |
Venus (in Leo)
Time: 11:15 PM MDT
Instrument: Visual + Binoculars
S&T Chart Reference: 34, 35, G
Regulus could not be seen as a separate entity but it did make Venus appear misshapen at its SE limb. At 10:40 PM, Regulus couldn't be seen at all. I used the binoculars to view the occultation and also identified the star 31 Leo below Regulus. I did not see Regulus appear on the NW limb later in the evening.

Noctilucent Clouds (NLC)
Time: 2:21 AM MDT
Instrument: Visual
The sun had already set in the west and the remnants of light indicating its last attempts to illuminate our sky was barely evident.
However, 20º - 25º to the NW were clouds that were very well illuminated - and it wasn't the sunset! Turns out it was noctilucent clouds. These electric blue clouds also called "polar mesospheric clouds". Ice crystals at about 80 - 85 km above Earth reflect the Sun's light during a period of time from about 90 minutes to about 2 hours after sunset or before sunrise. This occurs at latitudes 50º - 70º north and south. We were at 52.3488º N. The clouds are visible only when they are illuminated by sunlight below the horizon while the lower layers of the atmosphere are in Earth's shadow.
A beautiful sight. A moving experience in the badlands of Alberta.
Constellation: Cassiopeia
Asterism: Teapot
Messier Object: M31 (Andromeda Galaxy)
Planet: Saturn (in Sagittarius)
Location: Banff National Park, AB We had a fairly open campsite so had a section of sky to observe. With the sounds of the coyotes calling in the distance, there was a quick realization that we were in the wilds of the Rockies. |
M31 / Andromeda Galaxy + Cassiopeia
Time: 11:32 PM MDT
Instrument: Visual
I used Cassiopeia's Navy-Shedar-Caph "arrow" to find the two lines of stars that are part of Andromeda. It was then easy to locate the faint oval fuzzy in the night sky. The centre did appear brighter than the exterior portions of the oval. The trees hid the Square of Pegasus that I usually use to locate M31.
Saturn (in Sagittarius) Time: 12:04 AM MDT Instrument: Visual Saturn appeared to be about 7º away from Kaus Borealis, located at approximately 2:30 o'clock from the star. Did not use my binoculars to visualize the rings. |
This session was devoted to lunar observing.

Relatively clear with just a light breeze. We had had a big thunderstorm when we were setting up camp. Felt like Dorothy in the Wizard of Oz, just waiting for the wind to lift us inner tent up into the storm. The early evening was cloudy but it did clear for some viewing. Because of the size of the Moon, it negated any chance of viewing the star field this evening.

Conjunction (Mercury-Castor-Pollux) + Venus The Moon was beginning to rise in the East and obliterating chances of seeing stars in the East and South. Looking westward, I located Mercury 5º above the horizon and within 10º of Castor & Pollux. Venus was nearby and only 15º above the Grasslands horizon and at 10 o'clock from Mercury. Although a bit bleached out by the Moon, these were easily located and identified. |

No wind or clouds but felt there was more humidity here than the night before in Agawa Bay. Also, smoke in the atmosphere may also be limiting seeing and transparency. To add to the wonder of the night was the baleful loon calls across the lake around midnight. Some of the evening was spent observing the moon; read all about it in Lunar Session - June 20, 2018.
Venus (in Cancer) Time: 10:35 PM EDT Equipment: Visual + Binoculars S&T Chart Reference: 24 The stars of Cancer couldn't be seen that well so used SkySafariPro to determine the constellation was Cancer. Venus was so close to Asellus Borealis (γ) and Asellus Australis (δ) that the stars couldn't be seen. Even with binoculars, ι and Acumen's (α) were a challenge and β wasn't visible at all. |

Libra
Used the binoculars on the side deck after seeing Jupiter through our bedroom window. I wanted to determine where Jupiter was in relation to the α Librae-β Librae line. Jupiter was now above it but more importantly was once again seeing the double star at α Librae. Was also able to see two other bright stars with the binoculars that I later determined were 5 Librae and μ Librae.
α1 - larger of the two in the double, brighter and yellowish
α2 - much smaller, almost pinpoint. Couldn't determine a colour.
Jupiter

SUCCESS! Despite the almost full Moon, I located Cepheus above our roofline. Visually: was able to locate δ Cephei. Binoculars: Used the binoculars on a tripod and located δ, ε and ζ Cephei but could not positively identify the companion star. Telescope: I used the 10" Meade SCT to navigate to Cepheus then manoeuvred to δ Cephei, and there was the companion star HD213307. δ Cephei was bright yellow and almost double in size compared to its blue-yellow companion. There was a row of 3 stars below them and then discovered the centre star (H4) was also a double (using averted vision). All the other stars in the FOV were fairly faint. More time required at the eyepiece. |

Woke up to the Moon shining in the bedroom window, Jupiter not far from it. I again watched the Moon between the clouds in the partly cloudy skies - both visually and with binoculars. Jupiter was relatively close as well. In a large sucker hole was α Libra (Zubenelgenubi) and β Libra (Zubeneschamali), but Brachium was in the cloud cover below. Jupiter had certainly moved closer to α and was almost sitting centred on the α-β Librae line. |

1- @9:27 PM: Had to view the Moon and Leo between the clouds. Could easily identify tiny Regulus and 31 Leo in close proximity. Regulus was just tot he south of the Moon's south limb terminator; the terminator was parallel t the line formed by Regulus and 31 Leo. 2- @10:30 PM: Still catching between cloud cover intervals. Moon had moved a bit SE of its previous position. Besides Regulus and 31 Leo, ν Leo was now faint but seen with the binoculars. The Moon looked to be sitting at the intersection of Regulus-η Leo and 37 Leo-ν Leo. 3- @ 11:28 PM: The Moon had again moved SE of its previous position. 4- @ 1:28 AM: The Moon had moved to a position east of Regulus and looked to be nearing the intersection of Regulus-θ Leo and 37 Leo-31 Leo. At this point, it was very low in the sky, about 10º - 12º above our backyard horizon. 5- @ 2:05 AM - 2:20 AM: The Moon again had moved a bit SE from its previous position and was now below θ Leo-Regulus line. It was also a few degrees from the horizon. at 2:20 AM, it disappeared from our view. Interesting to watch the glow in the sky disappear at the horizon s the Moon set. |

Jupiter (in Libra) Visually: It was close to the α Librae-β Librae line. Binoculars: The moons were not aligned but rather formed a saucer beside the planet. Could not see the bands on the planet. Telescope: Bands were almost vertical (relative to our horizon). The Giant Red Storm (GRS) again was not seen. The saucer of the moons supported the planet and were left-right reversed to my binocular view. |

All 8 main stars of the constellation could be found in the northern sky above our neighbour's trees. My target for tonight was δ Cephei. After blocking out their street light, I located the area of δ Cephei visually and then with the binoculars. I found the variable Cepheid but could not make out the 2 stars of the double, just a single bright star. Will need to go out again and confirm this find with binoculars and then with the telescope.

Jerry and I were in the back yard - me observing and him astroimaging. No wind or clouds bu there're may have been a very light haze. Dew is settling on surfaces. Visibility and transparency were not as good as a couple of nights ago.
Venus Venus was very bright in the SW sky at about 25º to 30º above the horizon. It has changed position from the previous night's location. It has moved quite a bit from the Ain-Elnath line to being between ζ Tau and Elnath. Also tried using the Venus-Capella line to locate M37. Failed. |
|||
|
M37 / NGC 2099 Could make out all of Auriga's stars and I knew that M37 was west of the line formed by theta Aur and beta Aur. Could not see it visually. Using binoculars, I put Venus at 7 o'clock in my FOV which put the top of the neighbour's clothesline at the top of the FOV. I went almost straight up from there but couldn't see the open cluster. Will try earlier in the evening next time when Auriga isn't setting and, when higher, will make star-hopping a lot easier - especially if observing conditions improve. |
||
Jupiter Libra was almost on her side in the southeast sky. Jupiter was located very close to the line between α and β Librae as compared to May 8/9, 2018. I used binoculars to see the moons - only saw 3 (Callisto, Europa and Ganymede). I guessed that Jupiter was bright enough to hide Io, the one closest. Then Jerry set up the telescope to look at Jupiter. This confirmed my binocular view but also provided a view of Io. |
|
||
Ceres (Minor Planet) I used ε Leonis and μ Leonis to locate κ Leonis. Cancer took some staring for a few minutes so did find ι and Asellus Borealis. Using an imaginary line between ε Leonis and ι Cancer, I confirmed κ Leonis. Ceres, when centred in my FOV, was at 5 o'clock to κ Leonis but wasn't as bright. Averted vision was sometimes required to see Ceres. It had helped to study the star charts in advance of this search! |
|
||
Boötes Time: 12:03 AM ADT Equipment: Visual + Binoculars S&T Chart Reference: 42, 44, 53, 55 Arcturus was located high above Venus. I took my time to find all the stars of the constellation because of the less than great seeing and transparency. The part I couldn't locate was the 'arm' from Seginus to what I call the 'Asellis Triangle' - Asellus Primus, Asellus Secundus and Asellus Tertius. |
|||
Lyra Time: 12:05 AM ADT Equipment: Binoculars S&T Chart Reference: 63 Saw Vega high in the E-SE sky and could faintly make out some of the stars in constellation. Used my binoculars to find two sets of double stars - ε Lyrae and δ Lyra. Success! |
|
||
Scorpius On going through my scratch notes, I realized I had also seen ω1 and ω2 that were very bright adjacent to Graffias. |
|||
Cygnus Time: 12:20 AM ADT Equipment: Visual + Binoculars S&T Chart Reference: 62, 73, H While looking at Hercules about 20 minutes earlier, I noticed Deneb but ignored it for the time being. Being determined, I located the swan's stars despite the sky conditions. Certainly her wings took a bit of effort and not quite sure if I actually saw ι2 and ζ or just imagined them. Seeing Albireo, I easily located the Coathanger. |
|||
Coathanger / Collinder 399 / Brocchi's Cluster |

We were driving home from SCO when a red object appeared on the horizon before us - Mars. It was a definite red in appearance so no question as to its identity. In lined with it were 2 more planets - Saturn and Jupiter. Couldn't see what constellations they were in due to the internal reflections of the car's windshield and lights of oncoming traffic. Mars was approximately 5º above the horizon.

Constellation: Ursa Major (UMa) Saw this 3 nights ago at SCO through Bruce Hamilton's telescope. Used two stars in UMa (Dubhe 7, 23 UMa) to locate M82. Earlier tonight, I located the elongated shape in my 10x42 IS binoculars. Used the line between these 2 stars then went 'up' just past the halfway point towards 23 UMa. The telescope provided a much grander view of this galaxy. A bright nebulous oblong object, particularly bright in the centre. It almost appeared as if the bright centre cut the cigar in half. |

Constellation: Coma Berenices Searching through the night skies with our SCT. Looked specifically for Coma Berenices then pushed to α Com and M53 just up from it at about 11 o'clock. It is fairly bright and condensed, but a few bright stars were seen with averted vision. These stars seemed to provide a bright centre as opposed to the consistent brightness across the globular cluster. |

Jerry and I were the only 2 at SCO this evening. The wind made it feel colder than was. There were ripples on the pond in front of the observatory and on the river. No clouds. No flies! First time using my Sky Quality Meter (SQM)!
|
Venus (in Taurus) Time: 9:08 PM ADT Instrument: Visual Went out to the road to get away from the trees. Venus appeared to have moved to the left of the line between Elnath and Ain and also lower in the sky, or so it seemed. While looking for ζ Tau, I came across a very red star - Betelgeuse! |

Winter Circle A happy coincidence was that while searching visually and with binoculars, I saw a bright red star at the same level as ζ Tau but much further south - Betelgeuse! |

Cancer, M44/Beehive Cluster/Praesepe, & M67 I actually found M44 while searching in that area for α Serpens. Noticed it visually then used the binoculars. After that, I took some time to locate the faint stars of this constellation, i.e., faint relative to other stars adjacent to it. I viewed the two Messier Objects visually, with my binoculars and then Jerry located them with our 10" Meade SCT. M44 / Beehive Cluster / Praesepe M67 |

Leo Minor I used Adhafera and Rasalas as a base for the search. Looked halfway along that line then moved my eyes upwards a bit before putting up my binoculars. Imagine my surprise when I saw 4 stars in a tight cluster in a rectangular formation. Using SkySafariPro, I identified them as 27 LMi, 28 LMi, 30 LMi with the fourth star perhaps having two components - UU LMi and HD90024 - that appeared as one entity in my binoculars.

Draco Could make out the general shape of the constellation then set to work to find three pairs - binary double (ν1 & ν2) and two optical doubles (16 & 17, and 39 & HD238865). Guess the others will come later.

I spent part of this evening searching for the stars of Cancer, a constellation I hadn't found before/ While trying to locate the stars visually, I noticed a faint fuzzy in the area. With the binoculars, I found this beauty that completely filled my FOV. No evidence of any true centre, other than some of the stars being slightly closer together.

Jupiter (in Libra) Binoculars: @ 10:56 PM - Located Jupiter and noted the location of its 4 Galilean moons. Telescope: @ 11:19 PM & 11:53 PM - Jerry set up the telescope for me. Saw Jupiter at two times. At 11:53 Io was touching the SW limb. Because of Io's proximity to Jupiter, I couldn't see Io with my binoculars.

Minor Planet - Ceres (in Cancer) Our scope had not been previously aligned; it went in the general direction so had to use the hand control to locate the related stars in Cancer using SkySafariPro and Chart 35 in the S&T Pocket Sky Atlas.

The Moon rose earlier last evening but we did not notice it while out at SCO. Once we turned onto the road that led to Hwy 101, it was just above the horizon. Once on the 101, the Moon was right in front of us. Jerry noticed a "star" below it that was too bright to be a star. He was correct - it was Mars! The distance between was about x3 the diameter of the Moon or approximately 2.5º apart.
When we arrived home, Mars could be easily seen visually below the Moon.
Jerry went out onto the front lawn and took a photo; I sketched it.

Light wind, no clouds with only occasional very high clouds. Mosquitos have disappeared but the spring peepers continue to serenade us. On this night, I was observing with Melody & Bruce Hamilton, Blair MacDonald, Matt Dyer, Mark Dryden, Jerry and the Desveaux family of four. Lots of observing fun and laughter.
Spring Peepers serenaded us most of the evening. An owl made its presence known in the latter part of the evening. The flies came out as the sun started to set but soon disappeared - and they didn't bite (at least they didn't bite me). A dominant (male? nesting female?) Canada Goose met us on the road near SCO and continued to harass 2 other geese on the pond beside SCO. Bruce brought his "new" scope to try it out. Jerry realized when setting up his scope that he forgot the counterweights so had to go back home to get them.
Humour: Melody had sent an email earlier that had autocorrected "binocs" to "bingos". We used our "bingos" numerous times throughout this session. Laughter about "Bingo Night at SCO" all evening!

Canes Venatici Time: 10:42 PM ADT S&T Chart Reference: 43, 32 Instrument: Visual + Binoculars Melody and I found this constellation again. At this pointing time, it was almost perpendicular to the horizon between Leo and Boötes. Once we identified this constellation, we looked east of Cor Caroli (α CVn) to find the double star CVn 15/CVn 17. In line with them was a third star - HD114905. |

Jerry and I woke up shortly after 6 AM. Clear sky with no wind.
And there before us was the main reason for the early rise. The Zodiacal Light with Mercury rising in its centre over the mountains and Pisces on the edge of its glow was easily seen. For me this was especially exciting as it was the first time seeing the ZL in the southern hemisphere, and to see it rise adjacent to the volcanoes Licancabur and Juriques was breathtaking.
When Mercury first rose in Pisces, it appeared to be perched on the mountain’s edge like a small ball ready to roll down a knoll. Could see the planet both visually and with binoculars literally in the centre of the base of the ZL. With Aquarius in the sky, we thought we might be able to see Neptune that was located almost straight up from Mercury. Couldn't quite see it with binoculars but found the general area. It couldn’t be seen visually nor with binoculars, but we did locate it in the photos taken of the zodiacal light. Had we looked up towards the Zenith, we would have found mars in the Teapot. A wonderful start to the day! |

We spent the remainder of the morning packing up and arrived at the Calama airport around noon to catch our flight to Santiago. The Andes still had us in awe at its beautiful formations and colour.
What made it particularly exciting on this day was the trip that had us “officially” passing the Tropic of Capricorn – Latitude 25° 26’ 16”. There actually is a sign indicating its location and its where this picture was taken of the 4 Amigos – Melody, Dave, Jerry and me – at 1:10 PM. The desert expanse was mind boggling with very little if any plants on the desert expanses. There was one volcano en route that showed steam coming from its cone, reminding us this is country is part of the Pacific rim volcano ring. Arrived at Laguna Miscanti (elevation 13,668 ft / 4,164 m ASL), at 1:20 PM. The “lake” was surrounded by mountains and their volcanic peaks, most notably the volcano Miñiques whose lava flow separated Laguna Miscanti from Laguna Miñiques. The first thing we encountered upon arrival was a herd of vicuña on the gentle slopes leading down to the laguna and at water’s edge.
Humorous Side Story: Our car, driven by Charline, had never been the lead car on excursions so “ate the dust” of the cars ahead of us on the numerous unpaved desert roads. On this day, it was warmer than usual, so Dave requested the air conditioning be turned up. Unexpectedly, a large plume of dust spewed out over Charline and me in the front seat which had us choking. Laughter prevailed throughout the car for several minutes! Dave suggested there must be 4 speeds of air conditioning in Atacama cars – low, medium, high and Atacama dust storm. That had us laughing even more! |
|
Back to the Lodge for supper and for what we thought might be another night under the stars. That was not to be. We were informed upon our return that Latam Airlines was going on strike! Our flights to Santiago and the consequent connection to our flight home on Air Canada were in jeopardy. Jerry spent a lot of time on the computer and phone getting flights for him, Melody, Dave, and me. Thankfully, he was successful. The airline strike certainly put a damper on that night’s observing. Melody located and viewed the remaining objects she wanted to find but did not have time to sketch them. I just didn’t have the heart for any serious observing other than to stare at the skies for a short period and to realize it may be the last time to see these dark southern skies with all its wonders. A great disappointment for everyone that the trip was cut short. |

Melody, Judy, Jerry and Charline rose early to arrive in time for the tour bus to the Atacama Large Millimeter/submillimeter Array (ALMA). Due to its dryness, high altitude, scant clouds and scarce radio interference and light pollution from cities, this location was deemed one of the best places on Earth for astronomic observation. The bus turned to go up the mountain range towards the Chajnantor Plateau where the Array Operation Site (AOS) itself was constructed at elevation 16,000 ft / 5,000 m ASL. However, the tour was only going to the Operation Support Facility (OSF) at the lower elevation of 9,515 feet / 2,900 m ASL to reduce altitude sickness risks for staff, volunteers and visitors alike. One of the 66 AOS dishes was at OSF for repairs, and the two 28-wheel dish transporters were there as well. Talk about luck! It showed us how large these scopes and their transporters to the Array truly are. |
Back at the Lodge after supper, five of us gathered in the adjacent yard of the ladies' lodge - Melody, Charline, Dave, Jerry and me. I discovered that Leo had a backwards upside-down sickle. In looking closer at Eta Carina, I discovered the keyhole Nebula (NGC 3324). Dave pointed out the “false comet” seen in the tail of Scorpius. In observing it, I was able to identify NGC 6231, Trumpler 24 and Collinder 361. He also showed us the Tarantula Nebula in a 450 mm F5 Dob with 21 mm Ethos eyepiece, then he used OIII (oxygen 3) and UHC (Ultra-high Contrast) to demonstrate the variations in viewing. Fascinating!

A group of us in 3 cars headed out for the high Andes at 3 PM – me, Jerry, Melody, Charline, Dave, Fred, Malcolm Park, Greg Merrick and Rajeev Gupta.
Went south past Toconao then turned inland to Talabre Viejo where the paved road became a dirt road, with the road edge ‘curbs’ formed by the sands ploughed up providing guidance there and especially on the return in the dark. The we started the climb the wind-blown virtually smooth hillside. There were several stops for sight-seeing – volcanoes Simba & Pili and Láscar (most active volcano in Chile), and Cerro Tumisa. Láscar was especially interesting with its numerous craters.
We tried to climb the cone of a known crater in the area, but the gas engine cars couldn’t handle the combined altitude and incline, then there it was as we came over the crest of a hill – Laguna Leija! Elevation: 14,117 ft / 4,303 m ASL. Salt-crusted shorelines surrounded the lake and the cloud-covered Argentine Andes way off in the distance provided a lightning show later in the evening over the Argentinian border but no thunder due to distance away or lower O2 at that altitude. Maybe both. |
And was it ever COLD!! With the high-Andean winds and a big temperature drop, every piece of winter gear was necessary. The lee of the cars provided some protection. The Milky Way above the mountains with the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) with their reflections in the waters of Leija were breath-taking! No twinkling at this elevation! Stars were like small diamonds – so bright and so clearly defined. Left us speechless as we took in yet another “oh, wow” moment.

We once again had a road trip, this time travelling 62 km from San Pedro de Atacama to Laguna de Chaxas (Chaxas Lake) in the Reserva Nacional “Los Flamencos”. On the way back, Charline (aka driver/tour guide) remembered a side trip she had taken on a previous Atacama trip to a beautiful valley oasis – Valle de Purques – on the mountainside from where we could see Licancabur, Juriques and the ALMA Operations Support Facility (OSF). One would never know this amazing, fertile place was in the middle of the desert where a farmer was obviously growing some crops (including corn) along the stream bed! |
Set up for the observing session around 8:00 PM. No clouds or wind. Clear skies.
Some of this session was with Melody, Dave and Charline; Jerry visited occasionally between times when he had to deal with his astroimaging equipment. Went back to our lodge at midnight when I became too chilled to remain outside.

Vela (the "Sails") To find it, it helped knowing its relative position to Carina and the η Carina Nebula. Still needed to stare a long time at that part of the sky to determine its general location using the shape of the constellation, then finding the specific stars. Didn't locate them all initially but did find most as the night wore on. |

We were on the road at 7 AM for a 2-hour drive (98 km/ 61 miles) drive to the El Tatio geyser field – elevation of 14,173 feet / 4,320 m ASL). We saw the sun rise over the Andes and mention numerous vicuñas along the roadways. What sights! Then there it was - El Tatio! It’s an amazing place with over 80 active geysers – geyser cones, fumaroles, steaming soil, mud pots, and sinter terraces. It’s the 3rd largest geyser field in the world and the largest in the Southern Hemisphere. Back into San Pedro for a Chicken enchilada crema supper– fabulous! We also picked up some empanada pollo for tomorrow.
We spent the rest of the evening at the Lodge observing the night skies. I managed to get most of the targets for this evening. One pleasant surprise was Scorpius that rose on its side well above the horizon. I also watched as α Crux rotated 90° in orientation for “SE” to “SW”; read about it below. When I became chilled enough, it was time for bed.

All of Scorpius was above the sky line! Haven't seen it all above the horizon since Dead Horse Point State Park, Utah (May 2017) and Acadia National Park, Maine (August, 2017). Although the sketch shows it at an angle, it truly was lying on its side along the horizon with θ and ι only 1º above the horizon. Despite the lower declination, I was able to see how close Shaula and Lessath really are. |

In the early afternoon, we visited the ancient village of Tulor de Aldea. Around 4 PM, it was decided the excursion to Valle de la Luna was postponed to another day because of incoming clouds from all sides (the only time we saw cloud cover the whole trip). Without the sun, we would not be able to see the effect on the Valley as the sun set. Consequently, I spent the early evening viewing the night skies with Melody, Charline, Dave and occasionally Jerry (who visited between adjustments to his astroimaging equipment). Headed to bed at 11 PM.

Herschel's Jewel Box / NGC 4755 In looking through Charline's telescope, it was so easy to see the strs differentiated in the teardrop. You could also see where the stars were brighter/clustered in the open cluster and where they were fainter. |
Large Magellanic Cloud (LMC) / PGC 17223 / Nubecular Major The LMC and SMC are ever present in the night skies. They continue to provide "oh wow" moments every time they are seen. Guess I just can't believe I'm seeing them. |
α Eridani / Achernar (in Eridanus) Binary star system with a companion known as Achernar B. Magnitude 0.45, 9th brightest star in the night sky. Tiny but regular variations over 1.26 days caused by actual complex pulsations, or by rotation bringing dark star spots in and out of view. |
Orion & M42 Charline told us the 3 stars in Orion's Belt were known as the "Las Tres Marías" (the 3 Marys), i.e., the 3 Marys who were present at Christ's crucifixion. She then showed us M42/M4 3 through the scope - a very nice version to see. Also used my binoculars to compare the size and nebulosity. |

Carina ("Keel") Carina is one of 3 parts that was once the large constellation Argos Navi. It is circumpolar and is the 3rd largest constellation in the sky. It was very easy to identify as were ε and β. The other stars were very difficult to identify. θ Car was easier to find because of its proximity to the Southern Pleiades. Canopus is the next brightest star in the sky next to Sirius and never sets below the horizon. Absolute mag -5.53. |
|
Eta (η) Carina / NGC 3371 Eta Carina is an emission nebula. I had been looking at Carina in an attempt to find all of the constellation. Charline was able to locate the η Carina nebula in her telescope and shared the sight with us. Almost looks like the Trifid Nebula. Apparently, this nebula is 4x the size and even brighter than the Orion Nebula. Within this nebula (we later discovered) is the Keyhole Nebula, located just to the right of η Carina. Following this viewing, I looked at the nebula with the binoculars. |
|
|
Southern Pleiades / IC 2602 / θ Carina Cluster (in Carina) After I saw what looked like an hour glass on the left and other stars to the right in my binoculars, Charline showed me the Southern Pleiades in her telescope. The binocular view wasn't as good as the scope's (obviously!). NOTE: θ Carina is the brightest star at mag 1.9. It also has the obscure name of "Vatharz Posterior" meaning "succeeding one of the waterline". This probably refers to the waterline alongside of what was once referred to as the Argo Navis. |
Jupiter (in Libra) The constellation Libra was easily located after noticing bright Jupiter also in the same portion of sky. Jupiter was located a little below the imaginary line from β to γ Libra.
|
Hydrus (Water Snake) I was looking to see if Achernar had gone below the horizon when I saw a couple of stars at an angle to each other above and to the left of the SMC. SkySafariPro identified the pair as 2 stars of Hydrus. |

After supper, we had a private tour of Alain’s telescope field. Melody and Dave didn’t feel perfectly well but Jerry and I had altitude sickness meds and felt fine. Alain (Owner of the SPACE Lodge) introduced us to the Southern Hemisphere skies and provided our first viewing of some of the southern wonders overhead. I was amazed at the size of the Coalsack – about 7° x 5° in the sky! Dave also explained how to find the globular cluster Omega Centauri (aka NGC 5139) – the largest globular cluster in the Milky Way. Melody gave us a Southern Hemisphere Star Chart that Bruce had found online. Came in handy throughout the trip. I became chilled so headed back to our lodge to get warmer clothes but decided instead to just go to bed. Lights out at 10:30 PM.

We had just arrived in Atacama then went for dinner. Upon return to the Lodge, we opened our car doors to be greeted by the southern Milky Way and the Large Magellanic Cloud. So much larger than envisioned! This was our first “OH, WOW!” It literally kept me planted beside the car for a few seconds as I attempted to take it all in. "Large" as a descriptor doesn't do the LMC justice. It was so much larger than the photos suggest.
The night sky was so expansive with no interference from trees, buildings, or clouds. So much to explore! It was so different from home. Low humidity meant we didn't have to use warmers for telescope lenses nor to protect any books or papers we were using. Virtually no wind at night but cold, nonetheless. Dave led us to discover the Alpha Centauri Globular cluster. Another "Oh, WOW!" moment.

Couldn't see the majority of stars in Virgo but could see what I thought was Heze (ζ Virginis), a double star. Because of the clouds, the Moon had a hazy glow around it. With the binoculars, I could barely make out the features.
Couldn't make out the double star in binoculars. Could not see Spica due to neighbour's house blocking the view from the horizon.
This session was devoted to lunar observing.

Temperature was below 0º C with clear skies. the 3 planets were viewed from kitchen door window, easily seen visually.
Jupiter and Mars were seen in close proximity, with Mars adjacent to Zubenelgenubi in Libra.
Mercury was seen just above our neighbour's roofline towards the street side of their property. I briefly stood outside to view it. It was quite clear and easily identified.

Some cloud on the horizon that disappeared shortly after our arrival. Light wind. Our older granddaughter, Brianne, was interested in what we did and she arrived shortly after we did to enjoy an early morning view of the skies.
Conjunction: Jupiter-Venus (in Virgo) Planets came up and peeked through the clouds before rising above them. Venus was very bright in comparison. For some reason, I could not find Mars near the star Porrima ("above" Spica in the morning skies).

Puppis
Time: 6:30 AM AST
Equipment: Visual + Binoculars, 10x30 IS
S&T Chart Reference: 26, 27, 28, 29
This constellation is normally seen in the Southern Hemisphere, and represents the stern of a ship. It was part of a larger constellation "Argos Navis" before it was divided into Puppis (the poop deck), Carina (the keel) and Vela (the sails). I saw a triangle below Sirius that was not much above the horizon. This unknown triangle piqued my curiosity. Had to use SkySafariPro to help establish the identify of the three stars. Surprised, or what!
Taurus & the Hyades
Time: 6:30 AM AST
Equipment: Visual + Binoculars, 10x42 IS
S&T Chart Reference: 14, 15, A
Aldebaran was still bright in the morning sky so showed Brianne some of the stars in the constellation but focused on the Hyades open cluster, using my new 10x41 IS binoculars. What a difference from the 10x30 IS!!
M45 (Pleaides)
Time: 6:30 AM AST
Equipment: Visual + Binoculars, 10x42 IS
S&T Chart Reference: 14, 15, A
After pointing g out Aldebaran and the Hyades to Brianne, I showed her the Pleaides. We could very easily see this cluster. She had seen it before but hadn't known what it was.

No wind. Clear skies. Waxing Crescent Moon. Jerry and I were in the backyard observing; the primary reason for this session for me was to observe the Moon with my telescope - Explore the Moon (Telescope) - October 28, 2017. I was also able to complete IWLOP 092 - Clavius.
(7) Iris
Time: 7:58 PM & 9:40 PM ADT
Instrument: Visual + Binoculars
Having found (7) Iris the night before (thanks to Dave Chapman), I was able to show Jerry where to find it. Aries was high above our house so was able to show him how to locate the minor planet using κ Aries. The relative distances cited last night were no longer true; it appeared that the distance between κ and (7) Iris had increased.
Melotte 20 (α Perseii Cluster, Collinder 39)
Time: not recorded
Instrument: Visual + Binoculars
S&T Chart Reference: 2, 1
Perseus was above the house across the street. The star Mirfak was easily identified but required binoculars to see the stars of the open cluster due to light pollution from the street lights.
Taurus & the Hyades
Time: not recorded
Instrument: Visual + Binoculars
S&T Chart Reference: 14, 15, A
Used my binoculars to look at Aldebaran. Also attempted to see the double star at σ Tau and the triple at δ Tau - no success. However, the Hyades open cluster was glorious!
M45 (Pleaides)
Time: not recorded
Instrument: Visual + Binoculars
S&T Chart Reference: 14, 15, A
First viewed the Pleaides visually that were easily found after seeing the Hyades. The used the binoculars to look closer at the "7 Sisters".
IWLOP #092 - Clavius
Exceptionally large crater seen at its best near the time of First Quarter and Last Quarter Moon. It is also visible in binoculars. Used some of the viewing time this evening for Explore the Moon (Telescope).

Moon Phase: Waxing Gibbous (59.7% illuminated)
Moonrise: 3:05 PM ADT, Sunset: 6:16 PM ADT
Moonset: 1:15 AM ADT (Oct 29)
R1: Located Clavius next to Blancanus on the terminator.
R2: Noted 4 craters in a unique half-circle of progressively smaller craters. Craters D, C, N and J on the crater floor began at Rutherford and ended near crater L.
C1: Found the overlapping crater Porter in the NE and the overlapping crater Rutherford in the SE. Craters C, D, J, N were identified on the crater floor; craters K, L, M were on or near the rim.
NOTE: On June 19, 2021, we had our Grandson for an overnight. I had the 10" Meade SCT set up and we looked at the Moon with a 9.7 mm eyepiece (x258 magnification). What was really cool was that he was looking at the mares shown on the S&T Field Map of the Moon and was trying to locate them naked eye. One thing I showed him was Clavius that was on the terminator. We could see a black floor, one exterior wall that was very well lit, and the top rims of two craters (perhaps C & D) looked like a pair of eyes peering out into the darkness.

No wind. Clear skies. First Quarter Moon. Jeff Donaldson had a neighbourhood outreach session and a few of the RASC Halifax Centre members were there with binoculars and telescopes to assist.
Dave Chapman showed Gillian and I how to locate Minor Planet (7) Iris in the constellation Aries. We had to put Hamal, Sheraton and Mesartim in our FOV, then focus on Hamal to find κ, then continue along that line to (7) Iris. It was almost equidistant, i.e., the distance between α and κ was equal to that of κ to (7) Iris. Very exciting! Thanks, Dave!

Aquila
Time: 9:05 PM ADT
S&T Chart Reference: 64, 65, 66
Instrument: Visual
Located Altair then was able to identify all the remaining bright stars in the constellation.
Saturn Time: 9:30 PM ADT Instrument: Visual + Binoculars Located the planet naked eye as it was quite bright in the south sky. It was in Ophiuchus between 45 Phi and Sabik. The best way to explain where it was located was to draw an imaginary line from Alnasi (the spout of the Teapot) to Sabik; Saturn was located just below that line a little less than half the distance from Sabik. |
|
M8 (Lagoon Nebula) Time: 10:16 PM ADT S&T Chart Reference: 67, 69, I Instrument: Visual + Binoculars The Milky Way was a bit soft during the part of the evening as well - haze/ humidity? The Teapot was partially set behind the tree line but I could make out Kaus Borealis and Nunki. Using Kaus Borealis, I went westerly along the tree line and found the Lagoon Nebula. The line of 5 bright stars with the surrounding oval-shaped nebulosity was easily identified. |
M20 (Trifid Nebula) |
Perseus + α Perseii Cluster Time: 11:05 PM ADT S&T Chart Reference: 2, 13 Instrument: Visual + Binoculars Again, Perseus rose high in the sky above the tree line. I focused my attention on Mirfak and the α Perseii Cluster. Tried to determine if there was a difference in Algol's brightness from the night before. |
M45 (Pleiades) Time: 11:20 PM ADT S&T Chart Reference: 14, 15, A Instrument: Visual + Binoculars As Taurus rose higher, M45 became visible as well. Always a joy to see this bright jewel. Initially viewed visually, then with binoculars where the star field filled the FOV. |
Cygnus + Omicron (ο) Cygni Time: 11:50 PM ADT S&T Chart Reference: 62, 73, H Instrument: Binoculars Jerry and Dave assisted in finding it by explaining where it should be located. No trouble finding ο2 and ο1, the latter with 2 stars. My challenge was finding the third star. After 20 minutes or so on my back on the bench in the Sky Circle just staring at this part of the sky - SUCCESS! Finally saw all 3 stars of ο1 in Cygnus! My frustrations are at an end! Should attempt to find it again with my 15x70 binoculars and perhaps the telescope at home. |
Hyades / Melotte 25
Time: 1:05 AM ADT
S&T Chart Reference: 15
Instrument: Visual + Binoculars
Noticed the open cluster below/near the Pleaides. Used the binoculars to look at the cluster, Aldebaran and briefly at the other stars in Taurus. Numerous stars were located around the "V" formation of Taurus. It was a very open cluster.
Constellations: Auriga, Canis Minor, Leo, Orion, Taurus

Orion, M42 (Orion Nebula/NGC 1976) + NGC 1981 + M43 (NGC 1982) Time: 5:25 AM ADTInstrument: Visual + Binoculars S&T Chart Reference: 14, 16, B This observations was in concert with observing the Winter Circcle and the Zodiacal Light. Betelgeuse, Bellatrix, Rigel, and Saiph. Also made out the upper 2 stars in the belt and their fuzziness/nebulosity. Upon closer examination of the sword, I could identify NGC 1981 (just above M42), M42, & M43. M42 and M443 were seen as a single unit a little bigger than NGC 1981 above it. No single stars were evidenced at this sighting. |
|
Winter Circle + Winter Triangle To my surprise, the first thing seen in the early morning was the Winter Circle. Capella and Aldebaran were the highest stars of the Circle. Orion's stars in the belt and sword were so easily seen naked eye. Some of Auriga was also seen. My second surprise was Procyon and Gomeisha were easily seen - the one constellation that to this date had escaped me seeing both stars. Sirius, Pollux and Castor were also identified. NOTE: The stars Procyon, Betelgeuse and Sirius comprise the Winter Triangle. At the later time, the Hyades/Melotte 25 was seen naked eye. |
|
Canis Minor Time: 5:23 AM ADT Instrument: Visual S&T Chart Reference: 25 Procyon was located as one of the primary stars in the Winter Circle. I then saw Gomeisa (β). Because of the tilt of the Circle at this time of year, Gomeisa was almost directly above Procyon and as easily seen naked yet. Finally saw Gomeisa! |
|
Castor & Pollux (in Gemini) Time: 5:23 AM ADT Instrument: Visual S&T Chart Reference: 23, 25 Winter circle was very high in the sky so Castor and Pollux were very easily found. Didn't look for the other stars in this constellation. |
|
Auriga Time: 5:30 AM ADT Instrument: Visual S&T Chart Reference: 12 Recognized Capella first as part of the Winter Circle and Winter Triangle high in the sky. Then noticed the characteristic pentagon of the constellation. DIdn't see nor search for δ Auriga. |
Leo Time: 5:30 AM ADT Instrument: Visual S&T Chart Reference: 25 Very readily identified the backwards question mark just above the tree horizon - Regulus, η, Algieba (γ), Adhafera and Rasalas. Didn't search for κ or λ. Leo's hind end (Denebola) was below the treeline but Zooms and Chertan were just peeking above the trees. I looked for but could not find ι or σ. |
Taurus & Hyades/Melotte 25 |

Identified Vega visually then used binoculars to view ε1, ε2, δ1 and δ2. Sheliak (β), ζ and γ were found naked eye.
NGC 869/884
Time: 8:48 PM ADT
S&T Chart Reference: 1, 2, 13
Instrument: Binoculars (10x30 IS)
I drew an imaginary line between Navi and Ruchbah in Cassiopeia then continued along that line a little over once that distance to find this double cluster. Both appeared as grey fuzzies with a few bright stars in their centres.
Cygnus Time: 10:30 PM - 10:38 PM ADT S&T Chart Reference: 62, 73, H Instrument: Kejimkujik's telescope I tried to locate 16 Cygni with binoculars but was unsuccessful. Chris Young used the Park's telescope to locate this double star and we discovered two in the same FOV - 16 Cygni and θ Cygni. The latter pair were located at 6:30 o'clock to 16 Cygni and were much fainter. |

M13 (Hercules Cluster)
Time: 10:50 PM ADT
S&T Chart Reference: 52, 54
Instrument: Visual + Binoculars (10x30 IS)
Gillian Webster requested assistance to find M13. I first showed her on a star chart where the Keystone was located relative tot he head of Draco which she knew. Using binoculars, we located M13.
Capricornus
Time: 10:55 PM ADT
S&T Chart Reference: 66, 68, 77
Instrument: Visual + Binoculars (10x30 IS)
Gillian asked for assistance in locating "Orion's Underpants", aka Capricornus. She easily saw it after I described it as a clown smile. I pointed out Algeidi (α), Dabih (β) and noted they were both double stars. Using binoculars, we were both able to see the double stars in each.
Neptune Time: 11:05 PM ADT Instrument: Binoculars (10x30 IS) Saw Fomalhaut in Pisces Austrinus and heard someone saw Neptune was in Aquarius (just above where I was looking). Looked for the planet and found it near Hydor. Bright blue, very clear limb borders compared to the neighbouring stars. |
M45 (Pleiades)
Time: 11:10 PM ADT
S&T Chart Reference: 14, 15, A
Instrument: Visual + Binoculars (10x30 IS)
As Taurus rose higher in the sky, M45 became visible as well. Always a joy to see this bright jewel, initially naked eye and then have the star field fill my binocular FOV. Glorious!
Perseus + α Persii Cluster
Time: 11:20 PM ADT
S&T Chart Reference: 2, 13
Instrument: Visual + Binoculars (10x30 IS)
Perseus rose high above the tree line and was very easily seen naked eye. All stars, including those in his 'arms' had previously eluded me but were now easily seen. Amazing to see! Using my binoculars, I looked more closely at Mirfak and its surrounding α Persii Cluster and at Algol. I had hoped to begin to track Algol's variability, especially now that it was at a minimum.

No clouds and only a very light breeze that gained a bit of speed before the evening concluded. Had 2 telescopes for use: 6” Dobsonian and 10” Meade SCT.
Around 9:15 PM or so, I used the 10” Meade SCT with the x2 Barlow. Thankfully this telescope tracked after I used the handheld device to find craters that looked interesting. Wondered whether Nonius was created by an oblique hit versus a direct hit. I found a “row” comprising Arzachel, Alphonsus, Ptolemaeus and Herschel. What a neat grouping. Because I turned the star diagonal to the other side of the scope, it made my image not only mirror-reversed but also upside-down – go figure! Also found a new crater – Spörer. |
In Arzachel, there was a well-lit, off-centre peak and two bands of low mountains. Also saw Rimae Arzachel. Alphonsus had a ridge going SE to NW that showed a little bit of shadow. The west side of Ptolemaeus looked craggy, perhaps ridged. A high peak in the east (adjacent to Ammonius) was clearly visible. Herschel had a conical shadow towards the NE and looked ridged down/up from that shadow. |

This was the second day and night hubby and I were with Dave and Christine in the back country at our first Big Muise Island Star Party. The day was beautifully clear and warm, another great day to lay in the hammock and peruse the Observer's Handbook chapters I hadn't read yet. In the evening, there were clear skies overhead with a light breeze - and our first sighting of the Northern Lights from Kejimkujik National Park.
Occultation: Moon and Aldebaran (in Taurus)
Time: 10:00 AM - 11:15 AM

The sketch and photo of the occultation is recorded in Lunar Session - September 12, 2017.
Aurora Borealis
Time: 8:10 PM
Instrument: Visual
Dave noticed an unusual brightness on the N-NE horizon that we thought perhaps was light pollution. However, when the brightness changed depth and shape, Jerry took a time lapse and confirmed it was indeed an aurora due to a solar flare.
Teapot + Scorpius
Time: 8:20 PM
Instrument: Visual
As we sat on the beach just past sunset, we watched as the stars of the Teapot in Sagittarius and those of Scorpius became visible in the south sky and provided guidance as to where the Milky Way would appear. Both were well above the horizon at this time of night. All 5 stars of the Teapot were easily located and identified. Antares showed as red in the sky and 3 stars in the scorpion's arc to its west were also visible.
Satellite (LAGE052) Time: 9:28 PM ADT Instrument: Binoculars Was looking for Corona Borealis ν1 and ν2 when a satellite came into my FOV near M13. Followed it through Ophiuchus and lost it in Sagittarius. |
Satellite (ORBCOMM FMI[+]) Time: 9:50 PM ADT Instrument: Binoculars Looking for the Coathanger when it came into my view near Altair and travelled down Aquila to λ Aquila where it disappeared. |

This was the first time Jerry and I were camping with Dave and Christine in the back country. It was such a success, we are continuing this as an annual event - the Big Muise Island Star Party. By special invitation only. :)
On this evening, there were clear skies overhead with a cool wind. The horizon to the East was hazy negating being able to see any stars above the far shore and tree line.

Neptune (in Pisces Austrinus) Time: 10:30 PM ADT Instrument: Visual + Binoculars (10x30 IS) S&T CHart reference: 76, 77, 78, 79 Located Fomalhaut then noticed Neptune at about 11 o'clock from Fomalhaut. Small blue dot, no variance or evidence of twinkling. |
Draco Time: 11:10 PM ADT Instrument: Visual + Binoculars (10x30 IS) S&T Chart Reference: 41, 42, 51, 52, 61 Easily found Kuma (ν) in Draco's head. Had the double stars (ν1 and ν2) been in the centre of the Dragon's head, they could have served as the Dragon's eyes. |
Observation 1: Sunspots Location: Home Clear skies with occasional clouds, light wind. Three areas of activity were seen. 1- Near the equator had what appeared to be two spots - one circular and the other oblong with a slight curve. NOTE: A photo in spaceweeather.com showed AR2677 and AR 2678. Not sure which of these two was seen. |

Very light breeze. Clear skies. Light pollution in the low horizon across the bay. The Moon also washed out some of the stars. There were clouds travelling over the Moon that did provide some "darkness" and allowed for viewing.
Uranus Time: not recorded Instrument: Visual + Binoculars (10x30 IS) Noticed a bright spot at about 10 o'clock to the Moon and a good distance away from it. Binoculars showed a blue, non-blinking object. SkySafariPro confirmed it was Uranus in Pisces. |

M23 / NGC 6494 For details, refer to Messier Catalogue - M023 (NGC 6494) - September 8, 2017. |

Boötes Boötes was in the opposite side of the sky from the Moon. I found Arcturus then located δ Boötes and Neckar (β). Thought I visually could see the bright location of the double, but turned out it was actually HD135631 and HR5673 very close together in a vertical line. I then adjusted where I should be looking - a little further away from the imaginary line between α and β and closer to the δ end of the line. Success! |
|
M45 (Pleiades) Even though the Moon was quite bright, the main stars could still be seen - Asterope, Sterope, Tyageta, Electra, Maia, Merope, Alcyone, Pleione and Atlas. The star field and nebulosity behind and around them was not visible with the binoculars. |

I was determined to find this cluster this evening.
Looking at the star clouds, it appeared to be twice as far from the Teapot's spout as were M20 and M21. I located them easily then continued to what I thought was M23. I drew the sketch of what I saw then confirmed in a resource that the drawn star pattern was indeed M23. Success! It looked like there were thousands of stars in the open cluster to give it a hazy appearance behind the brighter stars.
Constellation: Sagittarius Type: Open Cluster Magnitude: 5.5 Distance: 2.15 kly Size: 27' |
Asteroid: (2166) Florence
(2166) Florence is a 10.1 magnitude, 2.7-mile wide asteroid that orbits Earth every 2 - 4 years on average. Its distance is 1.8 AU and orbits between Earth and Mars. It is named in honor of Florence Nightingale (1820-1910), the founder of modern nursing. This 2017 encounter is the closest by this asteroid since 1890 and the closest it will ever be until after 2500.

From September 3 to September 8, I followed the asteroid as it passed through the skies above our home. The asteroid passed through several constellations - Delphinus, Vulpecula, Cygnus and Cepheus - in its trek past our planet. It was interesting to see the "speed" at which it travelled day to day let alone on any given evening. Fascinating. It first caught my attention as it was approaching Cygnus.
September 4-5, 2017
Time: 9:00 PM - 12:40 AM
High haze, 17º C, no wind. Used binoculars to try to find the asteroid. I found Cygnus 39 and Cygnus 41 but couldn't see the asteroid. Jerry then set up the telescope and camera and took a series of photos. It was then that after viewing the photos and comparing to star charts that the location of the asteroids was found. I then followed it through the star field for several hours and sketched its path.

Temperature: 12º C
Partly cloudy becoming clear. Light breeze.
Observation 1: There were 9 separate areas of activity, from very large to very small. (A) in upper left quadrant: One small black area with 2 even smaller areas adjacent to it. (B) in lower right quadrant almost on the centre line: 6 areas varying in size. The largest had a large perimeter of activity with 4-5 large areas that were black in appearance. The lowest sunspot and the one immediately below the large one were similar in structure whereas the other 3 had no visible perimeter around the area of activity. The limb definition was variable, indicating the heat radiation from the surface. |
|
Observation 2: Saw 4 spots in the upper left quadrant. The smaller ones seen in the telescope couldn't be found in binoculars. The one spot in the lower right quadrant didn't show the very tiny 2 areas of activity as seen in the telescope. |
|
Observation 3: Using the 25 mm eyepiece, caught 7 areas of activity in the FOV. Three of these areas had a grey area in which there was 1 to 5 dark spots of activity. The largest was located just off centre and contained 4 areas of activity varying in size. The 15 mm eyepiece more clearly showed there were 4 areas of activity; however, some of those areas could have been a combined large and small area. |

Cloudless, light breeze. We were parked at the side of the road overlooking a long, expansive downhill to the ocean below. Such an amazing view! Even with the peak of Cadillac Mountain behind us, we still had about a 270º view of the night sky. The reflection of the Moon on the ocean was quite memorable.

Surprised to see this constellation relatively high above the horizon (compared to home) and adjacent to Capricornus. Could identify all 9 stars visually. Talk about exciting! With the Moon having set earlier it was so easy to see this constellation above the ocean's horizon. Saw Fomaulhaut (α) first then identified the other stars visually (using SkySafariPro as an assist). Didn't use binoculars to see the double stars of γ and μ (if in fact they could be seen).
This session was devoted to lunar observing. Lunar Phase: Waxing Crescent (46.4%) Moonrise: 1:55 PM Location: Acadia National Park, Maine |
At 10:28 PM, the Moon was about 15º above the horizon and started to turn a yellowish colour. Watched its reflection in the ocean for the past hour - breathtakingly beautiful! Also used the binoculars to identify some of the lunar features.
At 10:44 PM, it was almost orange in colour and about 5º above the horizon. We lost our shadows on the mountain side. We watched as the Moon set (visually).

No wind. Scattered clouds. Due to the threat of rain overnight and the distance between the car and our walk-in site, we left our cameras and binoculars in the car. The evening started out cloudy as could be expected given the weather report but it provide an extended period of clear skies as the night progressed. The night sky at the rocky beach front to our site varied from beautifully clear to partial cloud cover. Jerry and I sat on a large rock to take in the darkness and the amazing sky above us.

Andromeda (M31) & Cassiopeia With the help of SkySafariPro, was able to locate Andromeda and its bright stars Alpheratz (α And) and Mirach (β And) above the distant tree line. From there we could locate Almach (γ And), μ And and υ And to draw the lines for her "legs". Didn't search out the stars for her "arms" but rather used Mirach and μ to locate M31 (Andromeda Galaxy). |

Draco Viewing Draco naked eye, we used SkySafariPro to wend our way around UMa and UMi. We started with the 4 stars comprising the head then identified Altais (δ), ε and φ - never saw χ. We then located θ and Edasich (ι), followed by Thuban (α). Using the app, we were then able to fill in the spaces between φ and θ (except ω). Once these were all found, it was so exciting to "see" Draco as it curled around the two Bears! |

Solar Eclipse! Totally Awesome!

How far will one travel to see a solar eclipse for the first time in their life? Does 4,393 km (2,739.7 miles) - one way - sound a bit far? Having just experienced my first solar eclipse, I can unequivocally say NO!
The planning of this trip began a year ago when Paul Gray had announced at a RASC Halifax Centre meeting that he had the perfect spot to view the eclipse - from the KOA in Grand Island, Nebraska. KOA reservations made last fall - check. Plan remainder of the 2.5-week trip to and from this exciting event - check. So, let's now focus on the experience in Nebraska. I remembered Roy’s cautionary note about experiencing the eclipse versus taking pictures. Consequently, I dictated notes to my phone so that my eyes didn’t have to leave what I was seeing for more than a split second.
The evening before the eclipse, there was a gathering of astronomers to determine the plan of attack for the next day based on weather reports and Jay Anderson's advice. Once back at our campsite, we decided we would travel further west from Grand Island, probably as far as Wyoming to ensure a clear sky. We left at 6:30 AM CST after a small breakfast, drove through dense fog across part of Nebraska before arriving at our sunny clear blue skies location on Hwy 85 north of Lingley, Wyoming at 10:30 AM Mountain Savings Time (MST). Interesting to note is that at one point when we turned towards Wyoming on Hwy 26, every other car (of which there were hundreds in the adjacent two lanes of traffic) headed north on Hwy 385 to Alliance, one of the sites suggested the evening before. We were grateful we were going another way, but perhaps we went further than needed.
We drove through Lingley (population 468, elevation 1,272 m) and parked on the side of the highway next to a farmer's field on the crest of a small hill. We arrived two minutes before first contact and had a phenomenal 360° view. Jerry quickly set up for his time lapse photography whereas I opened my binocular bag and witnessed first contact with filter-covered binoculars at 10:32 AM MST.
With the solar filters in place, the sunspots were seen. They would perfectly provide the reference points by which to observe the rate at which the moon covered the sun. Four sunspots were located in the upper right quadrant of the sun, starting near the centre and going from lower left to upper right. A fourth was noted between the first and second but it was very weak and small and not as clearly defined. Two more sunspots were also noted at about 7 o'clock on the southwestern limb.
I watched as each sunspot was hit by the limb of the Moon:
|
At 11:05 AM, I noticed the sun not quite as bright as it was earlier. The sky was getting just a bit darker and the colours of the landscape were subdued, not as vibrant as they were when the sun was full.
At 11:20 AM, I offered my binoculars to the family of 6 next to us. Each in turn had a chance to see in a much larger view how the moon was covering the sun and to see the sunspots in the southwest limb. So much fun watching their reactions, from the parents to the 6-7 year old. Also shared with a couple standing across the highway, and with a father and daughter who pulled beside us just a few minutes before totality.
At 11:40 AM, the temperature noticeably cooled, enough so that a sweater was required. Also noted that we were now being serenaded by chirping crickets. It was at this point I had total interest in what was happening around me versus recording the time frame. I did not note when the lower two sunspots were covered by the Moon nor the time and length of totality. I tried to remember Roy Bishop's description of what to expect but failed to do so in the excitement of what I was seeing.
I turned my back to the sun at one point and watched as darkness quickly approached. I likened it to being a teeny weeny little creature watching the great cape of Darth Vader billowing out as it approached and eliminating any hope of escape. I held my breath totally, enraptured as I watched it come across the field and overtake me.
What I saw next had me turning a complete 360°, and probably more than once in a couple of different directions in my attempt to decided which way I should look. A beautiful rainbow of colour appeared on the darkened horizon when the shadow overtook us. This was the one and only time I took a photo during the eclipse - a panoramic view of about 120° to 130°. Too many cars in the way to take the full 360. You can see the centre of the shadow as it rapidly travels eastward.

Totality was reached! Darkness was upon us. Regulus, Jupiter and Venus were seen but I didn't think to look closer for other planets (Mars and Mercury) and stars as suggested in articles previously read. The back orb covering the sun contrasted with the elongated translucent streams of the white solar corona that reached out into the now darkened sky. I stood there transfixed and could only think, "Oh, wow! This is really cool!" Thanks to Jerry reminding me that filters were not required at this point, I held the filter-free binoculars once more to my eyes to view the prominences at various locations around the moon's limb. Their fire engine red-pink colours were indescribably beautiful. I handed my binoculars to the daughter and father adjacent to us for them to see them as well. The corona wasn't perfectly circular; longer spikes at 12, 2 and almost 7 o'clock were visible. The corona was spectacular; the extent from its source was astonishing. |
Once the binoculars were back in my hands and up to my eyes, Bailey's Beads appeared. Light came through the Moon's crater valleys and seemingly bent around the Moon's surface to produce a reddish glow on its surfaces, especially on the Moon's limb at 12, 1 and near 3 o'clock.
Then it happened! The "diamond"! It started as a small glimmer on the Moon's limb then shone blindingly just above the Moon's equator! Another wow. So cool! Gave me goose bumps.
According to the reference book materials, totality at our site was 2 minutes 11 seconds. It was such a short time. This wasn't long enough to truly absorb what was happening. Could a replay be granted?
It was now 11:53 AM. My wits are back (if they ever are) and I can once more record the events. Filtered binoculars and eclipse glasses were in use once more, and the air was still cool enough (for me) to require a jacket. The sun's light affected the colours around us, much like a spot light bleaches colours out; the dark greens of the field and nearby grasses had become a grey-green, shadows perhaps not as distinct. The crickets were still chirping.
The moon now began to reveal the sunspots it had earlier hid from our view:
At 1:14 pm, the eclipse was complete. The Moon lost contact with the southwest quadrant of the sun. Time to pack up and head back to the KOA. I now had another check mark on my Explore the Universe certificate submission! A short video of our experience can be seen at https://www.youtube.com/watch?v=k7HWur4Twp8.
End Note: Although it only took us 5 hours to arrive at Lingley from the KOA, the return trip took 11 hours. The distance between our eclipse location and the turnoff onto Interstate 80 should have taken only one hour but took 5 hours. Our heads hit our respective pillows at 1:15 AM CST, still whirring with the excitement of the day. Our trip home to Nova Scotia begins in 5 hours...

1- Went for a morning walk and saw the crescent high in the sky. Saw it visually only as we left for the walk.
2- When we returned to Mom's apartment, I used my binoculars to see a very brightly lit crescent. To the East, there was a small section that was partially visible before fading in the morning sky. There was very little if any breeze. A high hazy cloud allowed viewing of the Moon but couldn't make out details on the lit terminator. Could make out dark Grimaldi.

First noticed the Full Moon at 9:50 PM when on my way home. At home, there were wispy clouds travelling past the Moon until 11:02 PM when the sky opened for a clear view. Many features could be easily identified even though fully lit. Clouds returned and there was no opportunity to clearly view the moon again until 11:58 PM; the skies provided an opening until 12:10 AM when I called it quits.
Ejecta Rays: Mare: Sinus: |
Craters:
- Sharp and Plato on north Mare Iridium
- Gang of 4 showing up as very white
- Grimaldi and the darker Hevelius
- Shades of grey suggested Schickard and Schiller
- Manilius was found adjacent to the Haemus Mountains
- The rays of Proclus going north on Mare Crisium and providing a "white peak" on the shores of Palus Somni
Mountains:
No shadows on the mountains but many showed as whiter areas on the surface - Haemus, Jura and Apennine.

Fairly clear skies but slight haze and 99.3% Waxing Gibbous Moon affected seeing and transparency. Heavy dew in the early evening disappeared around 10 PM.
Ursa Major I was able to see all 7 stars quite readily at the first observation. However, all 7 stars appeared dimmer at the later observation, their brightness muted by the atmospheric conditioned and/or the Moon. |
Summer Triangle / DAVe A little breeze began at 9:06 PM but it disappeared around 10:00 PM. Located Deneb and Vega at 9:39 PM and Altair at 9:52 PM. Only some of the strs in each constellation could be seen so didn't spend much time looking - except around Deneb for Cygnus 16 and ο1. |
Boötes Saturn Saturn was easy to pick out in the sky just above our tree line. However, I did not see any adjacent stars. |
|
Corona Borealis Alpheca was very bright when it was first seen. With my back to the Moon, I visually could see Alpheca plus β, θ and γ. With my binoculars, I could also find ε; however, ι could not be identified in the slightly hazy skies. |
Meteor A bright white flash lasting ~ 1 second "downwards" in my perspective. Meteor flash went from NW to NE through Cepheus. |
Lyra

Walked to the deck side of the house and the shadow of the house next door to escape from the Moon and street ligh respectively. Cassiopeia was fairly visible from this location. All 5 stars could be seen but they were dimmed/muted by the atmosphere and/or the Moon. Given its dimness and that of UMa, I gave up for the night at 11:15 PM.
I spent som time doing general observations: General Session - August 6, 2017.

A few clouds with a slight wind. Could see atmospheric turbulence at the terminus and limb edges.
9:06 PM: The Moon finally rose over the houses across the street.
~ 10:15 PM: Moon was high enough it could be seen with the telescope. The rays of Kepler and Tycho were easily seen. Surface was completely bleached out; no real features were seen except for a few at the terminator. Attempted to draw Kepler’s rays. The features adjacent to Kepler on the Moon’s rim captured my attention so sketched them next.
Craters: Grimaldi, Kepler.
Found Craters not on the list: Byrgius, Byrgius D, Crüger, Kepler A, Lamarck, Marius, Milichius, Rocca

Windy. Cloud cover increased during the session. Good viewing until the clouds completely covered the Moon. Sucker holes thereafter. The sucker holes allowed for brief viewing of the Moon. One view (from Sinus Iridum to the Moon’s north limb) was only seen for about 30 seconds; this allowed for a rather hurried sketch.
Schikard was near the terminus. Its westernrim had shadowing and there was a crater at its southern end.
|
Identified Cavalerius, Hevelius and Lohrmann north of Grimaldi. Luna 9 landing NE of Cavalerius on Oceanus Procellarum. |
Identified Foucault and Harpalus in Mare Frigoris north of the Montes Jura. Also identified Babbage north of Frigoris with a crater on its floor (centred?). The latter was the largest of the 3 and was near the limb. |

Mostly cloudy skies that provided the occasional sucker hole for observing. Also windy.
Sunspot A sunspot (AR2670) was found using solar filters (ND5) on the binocular lenses. |
Lyra I was able to visually identify Vega. I then used my binoculars and in 1 FOV could easily see Vega, ε1, ε2, ζ1 and ζ2; δ1 and δ2 had to wait until the next tie there was a clear sky. |
Boötes Located Arcturus visually and attempted to identify the kite shape of the constellation. Could only identify ζ, η, ρ and Arcturus. The others were difficult to find naked eye. Having found the Big Dipper in Ursa Major (UMa)a few moments earlier, I pointed my binoculars up from UMa t find what I refer to as the "Boötes extension" - θ, κ, ι, and λ. ι was easily seen but I had identified it earlier as HR 5360 - not sure which it was. |
Summer Triangle Depending on the size of the sucker holes, all or a portion of the Triangle was visible. |
Ursa Major During one of the instances of a clear sky, I was easily able to see all 7 stars of the Big Dipper visually and located Mizar-Alcor visually as well. I used my binoculars to view Mizar-Alcor. Clouds negated the ability to locate Polaris. |
Cygnus I was looking for Cygnus 16 but couldn't find it. However, I did find a double star that unfortunately I didn't realize it was Omicron Cygni. Looking closer, I had Cygni 30 on the upper left and Cygni 31A in the lower right of my FOV. I found them by locating Deneb and then δ Cygni. From the imaginary line between them, I looked a little above it and a little less than half way from Deneb. Success! I will look on another evening when he Moon and clouds don't limit my "stare" time. |

The partly cloudy skies cleared by 8:30 PM so that all the stars in Ursa Major were visible at the earlier observing time. By 11 PM, the clouds covered the constellation completely.
Saturn Saturn was located visually earlier in this session. At the later time, I thought I had caught 2 moons in my sight. However, came to realize the brighter 'star' was ξ Ophiuchus and the fainter one was HR 6472. No moons of Saturn were seen. See the conjunction sketch below. |

Mostly clear skies that clouded over much of the sky as the night went on until ~ 11:15 PM when there was just a clear patch around the Moon. Most of the evening was spent on the ETM (telescope version) list. Found tonight were several craters, mountains, and valleys. Very excited about the ones found!
|
I was surprised that having missed one night of observing due to cloud cover that so many items could be seen tonight. I started with 30 mm eyepiece to sketch areas that caught my interest: Gassendi, Mare Iridium (north shore) and Sinus Iridum.
10:44 PM
I switched to the 10 mm eyepiece. Between Maria Crisium and Tranquilitatis was a very brightly lit circular crater rim with 2 rays emanating from it. I asked Dave Chapman about this and he explained they were called “rays” (deposits of light-coloured material from impacts). One ray touched the mountain/mare edge of Tranquilitatis whereas the other went between the two maria and faded into the landscape. The field between this crater and Tranquilitatis is darker than the field between it and Crisium. It had many white-rimmed very small craters or raised cones.
NOTE: On March 21, 2021, I learned this fan-shaped area was Palus Somni with Proclus as the bright crater on its rim. The bright areas within were minor craters. |
There were some areas seen that weren’t labelled on the RASC map provided:

Clear skies. My first attempt at viewing was at 7:34 PM but it was too bright. Went back out 1 hour later with better viewing of the features. After spending much time sketching, I then attempted to identify features required by the Explore the Moon (telescope version).
Although listed for the next day, I was able to see Mare Imbrium and Copernicus. North of Copernicus were 4 small craters that formed an upside-down and backwards “L”. Using a digital Moon Map, I was able to identify Timocharis, Lambert and Pytheas but was unable to identify the smallest of the four. It was just inside the mare adjacent to Monte Carpatus or just on its slope facing the mare. |

Satellite Time: 9:46 PM - 9:49 PM Instrument: Binocular 10x30 IS Entered my FOV at Mizar-Alcor then travelled through Draco to Deneb. I lost sight of it at 5ºN of Altair. |
Boötes Despite the Moon obliterating my view of numerous stars, the stars comprising the "kite" were found. Arcturus had been found earlier in the viewing session. |
Satellite Coathanger / Collinder 399 / Brocchi's Cluster Located Albireo in Cygnus, then found the 10 stars of the Coathanger. A satellite came into my view while looking at this asterism. |
Saturn Saturn was very visible just below Ophiuchus and above Scorpius (about 10 o'clock to Antares). The different scope meant the rings were seen differently and two of its moons were visible - Rhea and Dione. |

Ursa Major (UMa) All the stars were visible at 10:15 PM but it was 20 minutes later that Dubhe could be easily seen visually. Polaris could easily be found visually. Using the telescope at 10:44 PM, I looked at Mizar and Alcor, Mizar being the brighter of the pair. |
Cassiopeia Had no problem identify the 5 bright stars in this constellation.
|
Satellite Summer Triangle / DAVe |
M51 (Whirlpool Galaxy) Using the distance between Alkaid and Mizar, I looked below Alkaid just a little lesss than this distance and saw a faint, grey circular smudge. Not positive it was M51 but it was the only "smudge" in the vicinity. Next time look at the adjacent star patterns to ensure identification. |
Cygnus The Moon obscured the dimmer stars visually. At this time, the constellation was overhead. The stars ζ, η and ι were not easily seen visually. Used Albireo as a way to locate the Coathanger. |
Coathanger / Collinder 399 / Brocchi's Cluster Travelled down the stars of Cygnus to Albireo then found the Coathanger - all 10 stars were clearly identified.
|
Canes Venatici Decided to look for this constellation and one of the arms of Boötes because the sky in this direction was darker and not affected by the lights of Halifax. Using my S&T Atlas, I found this constellation lay directly below Ursa Major's handle. Specifically, Cor Caroli (α)was directly below Alkaid; this was easily found visually and I also looked for Arcturus as another guide. With my binoculars, I was able to find Cor Caroli. Jubilation at also being able to find Chara (β) with binoculars! It wasn't until I looked on the internet and at my map more closely that I discovered α was a binary star. I will look more closely next time. |
|
Boötes Saw most of the stars in Boötes except Seginus. Looking at the star Atlas made me want to look for an extension away from the "kite" that contained θ, κ and λ. I located Alkaid and looked one FOV above it and there it was. The 4 stars of the corner were very clear and were in 1 FOV of my binoculars. SkySafariPro helped me identify the names of the stars. I was thrilled to be able to find this group of stars using landmarks as guides. |
|
Lyra Searched for the Lyra stars in this constellation to confirm the two sets of double stars. Lyra ε1 and Lyra ε2 were easily found in binoculars. Following through Lyra ζ, I was able to locate the red and yellow Lyra δ1 and Lyra δ2 respectively. Vega, Lyra ζ, Lyra δ1 and Lyra δ2 were in one FOV and I was able to centre them in the middle of the FOV.
|
|
Delphinus Equuleus I looked to Delphinus and after several second found α, δ, and γ Equ. It took a while to find ε with the binoculars. In examining γ Equ, I could see two stars there - γ Equi + 6 Equ. At ε Equ, I could make out 4 Equ and 3 Equ. I didn't take the time to note the colour differentiation (if any) or brightness, Next time? |

This was my first time looking through our 10” Meade SCT and getting my brain wrapped around the mirror view. Without any go-to or other source of mechanical movement, Jerry and I had to manually move the scope to the desired position. We jokingly referred to this scope as the “push-to”.
There was disappointment in that some of the items listed at Q-day 0 could not be seen; they were beyond the dark portion of the terminator, such as Herschel, Ptolemaeus, Alphonsus and Arzachel. However, I was able to identify 2 items on the list for Q-Day -1:
Most of the 2 hours of this observing session was dedicated to sketching the Lunar X, first with 30 mm eyepiece and then the 10 mm. However, there was time to identify other lunar features.

Scorpius
Time: 9:40PM - 10:15 PM
Instrument: Visual
S&T Chart Reference: 56, 58, J
The second experiment of the evening. Wanted to see when the stars of Scorpius would become visible in the southern horizon (or at least when I noticed they became visible).
9:40 PM: Antares
9:48 PM: ν, Graffias
9:54 PM: π, ρ
10:12 PM: The stars below Antares in the constellation were visible above the tree line. Perhaps θ or η were faint or below the trees.
Cassiopeia Saturn |
Ursa Major Time: 9:50 PM + 10:37 PM Instrument: Visual + Binoculars 10x30 IS S&T Chart Reference: 31, 32, 33, 43, F I visually identified all the stars within Ursa Major, not just the Big Dipper asterism. I later used my binoculars to look at the optical double in the handle - Mizar and Alcor. |
Satellite (ISS) |
Satellite Time: 10:35 PM - 10:36 PM Instrument: Binoculars 10x30 IS Sighting was accidental. Looking at Antares with my binoculars when it entered my FOV. It disappeared near Spica. |
M7 (Ptolemy's Cluster) |
|
M22 |
M28 Time: 10:57 PM Instrument: Visual + Binoculars 10x30 IS Using Kaus Borealis visually and finding M22, I put the eyepiece back on the lid star in the lower left and M28 was readily seen as a round smudge. It had what appeared to be a brighter/denser centre. Couldn't discern any stars in the cluster with my binoculars. |
Scutum |
|
M8 (Lagoon Nebula) |
M11 (Wild Duck Cluster) Time: unknown Instrument: Visual + Binoculars 10x30 IS S&T Chart Reference: 67 I looked for the semi-circle of stars above the Teapot. Using my binoculars, I easily located the 'golf club' and 'golf ball' (aka M11). |
M20 (Trifid Nebula) |
M21 Time: unknown Instrument: Visual + Binoculars 10x30 IS S&T Chart Reference: 67, 69, I After finding M20 a few moments earlier, I went up a partial FOV at about 45º to M20 to see M21 very clearly in my binoculars. |
Meteor
Time: 11:09 PM
Instrument: Visual
It ran parallel to 2º - 5º below the line from Ascella to Kaus Borealis in the Teapot.
Libra Time: 11:29 PM Instrument: Visual + Binoculars 10x30 IS S&T Chart Reference: 46, 57 Libra was very low in the sky but I was able to see α Libra (Zubenelgenubi). The brightness of this star alerted me this constellation was now visible. I put my binoculars up to this star and had a long look at it to discover this was a double star - α1 and α2. Alpha1 was a bright yellow star and about twice the size of its companion. Alpha2 was a bluish star, fainter and seemed to be twinkling at times. I didn't look for the other stars in this constellation. |
Capricornus Time: 11:56 PM Instrument: Visual + Binoculars 10x30 IS S&T Chart Reference: 66, 68, 77 I moved to the far end of the gravel pads next to the trees in the west. Given Scorpius and Sagittarius had moved towards the west, I hoped to locate this constellation - and I did. Most of the stars could be located except ζ and ε that were hidden by a tree. After finding the constellation visually, I used my binoculars to look at α Cap1 and α Cap2 (Algedi) and had no difficulty doing so. |
NGC 7000 / North America Nebula
Time: 12:25 AM - 12:45 AM EDT
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 62, 73
Art Cole was at SCO tonight and pointed out NGC 7000. He pointed to Deneb in Cygnus and said it was just below it, that it looked like North America, including the Gulf of Mexico.
I used my binoculars and sat in the gravity chair in my attempt to find it. For the life of me, I couldn't find the dark Gulf to identify the nebula, even after 20 minutes of searching. However, maybe because of a strong desire to locate/see it, or because of my imagination, I thought I could faintly see it visually. Need another clear night to attempt again.
Kemble's Cascade
Time: 12:41 AM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 11, 13
Now that Cassiopeia was higher in the sky and away from the trees, I was easily able to visually determine where Kemble's Cascade was located and then to see it with my binoculars, including the hockey stick ending.
How to find Kemble's Cascade:
Place digit #1 (e.g., your left thumb) on Caph and digit #2 (e.g., your left baby finger) on Segin. Holding your fingers in that position and following the line/direction formed by Caph-Segin, move digit #1 on Caph to Segin so that digit #2 is away from Cassiopeia. The top of the Cascade should now be where your baby finger is located in Cameliopadardalis. Look for the hockey stick ending!

Clear, no clouds, light wind. Part of this evening was also general observing - General Session - July 26/27, 2017
Mare Crisium very visible. Its western edge was well lit and this edge formed part of the terminator. Dark floor in Crisium. Cleomedes seen very well above Crisium. Gang of 4 was visible. The southern end of the terminator appeared to have 3 dark valleys/shadows that made it look like a serrated edge. There were 2 more craters that I questioned as to what they were. Maybe Geminus and Endymion?
The shape of the whole Moon could be seen despite parts of it being in shadow. All limbs were visible – Earthshine.

New Moon. No wind or cloud.
Helped Jerry get set up for his astroimaging then sat and watched as the stars made their appearance in the night sky. New Moon today.
Saturn Time: 9:50 PM Instrument: Binoculars Saturn was located near the Teapot. Easily found due to its visual brightness. Using binoculars, I could determine it wasn't a "round" object but couldn't see the rings at this level of magnification. |
Jupiter Time: 9:55 PM Instrument: Binoculars I was looking for Spica (which I did find) but also noted Jupiter was once more near Virgo. |
Summer Triangle / DAVe
Time: 9:50 PM - 10:05 PM
Instrument: Visual
Three stars the asterism exposed themselves over a 10-minute period - Deneb, Altair, Vega.

Keystone of Hercule & M13 (Hercules Globular Cluster) I viewed the Keystone of Hercules that appeared overhead. M13 could be seen naked eye between η Herculis and ζ Herculis. I used the binoculars to confirm what I was seeing visually. I also viewed it again with binoculars after midnight when I was able to point out all 4 arms of Hercules to Jerry. I was amazed at how easy it was to find all the stars in the arms. |
Corona Borealis Ursa Major |
|
Cassiopeia Time: 10:12 PM + 12:00 midnight Instrument: Binoculars S&T Chart Ref: 1, 3, 72 All 5 stars were readily seen naked eye. Attempted to use binoculars but the multitude of stars in my FOV confused me. When I easily found this constellation at midnight, I decided to try to find Kemble's Cascade. |
Kemble's Cascade Time: 10:00 PM + 12 midnight Instrument: Binoculars S&T Chart Ref: 11, 13 Could find all of Kemble's Cascade at 12 midnight but could not find it around 10 PM when looking at Cassiopeia. A beautiful tumbling of stars that ended in the hockey stick. |
M4 (NGC 6121) |
Meteor M7 (Ptolemy's Cluster, NGC 6475) |
Scorpius Time: 10:34 PM Instrument: Visual + Binoculars S&T Chart Ref: 56, 58, J Scorpius was mostly above the tree tops but η, θ and ξ were below the treeline. I noticed the 'stinger' was quite bright so used my binoculars to look at the 2 stars - Shaula and Lesath. I wasn't disappointed. Both quite bright in a single FOV. |
M69 Time: 10:43 PM Instrument: Visual S&T Chart Ref: 67, 69 Located Kaus Australis and the adjacent sides of the Teapot. Put Australis in my lower right FOV and looked towards Nunki but just above the Ascella-Australis line. Found it with averted vision. It was a dark grey small fuzzy object. |
Cygnus Time: 10:52 PM + 12:35 AM Instrument: Visual + Binoculars S&T Chart Ref: 63, 73, H Deneb had come out earlier in the evening; had to wait to visualize the stars in Cygnus to find Albireo, Sadr and η Cygni when the sky was darker and the Milky Way was just starting to show up. Could easily see the wing stars from ζ to ι. The blue-gold of the double star Albireo could be seen but seemed to "twinkle"; could not discern between the 2 stars with the binoculars. Saw Cygnus visually again in the early morning - quite evident in the Milky Way. |
Coathanger / Collinder 399 / Brocchi's Cluster Time: 10:52 PM Instrument: Binoculars S&T Chart Ref: 65 Just put my binoculars to my eyes after locating Albireo and guesstimated where it might be located - et voilá! Just like an old friend. I love finding this asterism! All 10 stars were very clearly seen. |

Clear cloudless sky with no wind. Began looking for this thin crescent shortly after 8 AM. We made the mistake of searching low on the skyline before finding it in the SE and at about 65° - 70° above the horizon. Very difficult to find because of the clear skies and very bright sun.
With the binoculars, we could make out a dark smudge at about 8’clock. What was truly interesting was how there really wasn’t a terminator like there is at night. I could still make out the remaining part of the Moon, but it was more like a gradual diminution of light from the ‘bright’ crescent to the adjacent areas. The blue area of the Moon just blended gradually into the blue sky. Given the early hour, the sky was a beautiful blue!
Jerry had set up the binoculars on a tripod for my viewing as I couldn’t find it in my 10x30 IS. He then set up a camera on a tripod and captured a couple of beautiful pictures of the waning crescent; first picture was at 8:41 AM. We spent about an hour looking at the Moon until we could no longer see it in the brightening sky.

Instrument: Visual
Jupiter was located below Arcturus, halfway to the horizon.
Scorpius
Time: 1:30 AM
Instrument: Visual
S&T Chart Ref: 56, 58, J
Scorpius at this time of morning was mostly below the horizon. Could still see Antares, Delta and Graffias easily and perhaps π but the rest were out of observing range.
Capricornus Time: 1:40 AM Temperature: 15º C Instrument: Visual + Binoculars 10x30 IS S&T Chart Reference: 66, 68, 87 Sitting on Slapfoot Beach, Capricornus was right in front of us. The major stars of the constellation were easily identified, and α Cap1 + α Cap2 were easily identified in the binoculars. |
Lyra Time: 1:46 AM |
M8 (Lagoon Nebula) Time: 1:35 AM Instrument: Binoculars 10x30 IS S&T Chart Reference: 667, 69, I Was easily able to locate the grey smudge that had the line of stars below it. Not as well seen as in previous observations but easily identified nonetheless. |
M7 (Ptolemy Cluster) Time: 1:50 AM Instrument: Binoculars 10x30 IS S&T Chart Reference: 58, 67, 69, I The fog earlier in the evening had cleared off. Although the Teapot was low on the horizon, I was able to locate M7. The 5 brightest stars could be seen with slight nebulosity; the inner stars could be seen in the centre area but there were not very bright. |
Ophiuchus No wind and only the occasional cloud. Amazed at its size!! I was looking at Scorpius (visually) and noticed an arc of 4 stars above. Using SkySafariPro, I came to realize it was Ophiuchus. What a pleasant surprise! Unexpected discovery! Once all the baseline stars in the curve were identified, I then began the search upwards. WOW! It was huge in the night sky! The Teapot was very small by comparison. Note 1: When I used SkySafariPro, I also discovered that one of the "stars" in the arc was not a star but rather it was Saturn. Note 2: used my 10x30 IS binoculars to locate both Yed Prior and Yed Posterior. Couldn't see them as 2 stars using naked eye due to sky conditions. |

Coathanger / Collinder 399
Time: 2:05 AM
Instrument: Visual + Binoculars 10x30 IS
S&T Chart Reference: 65
After locating Cygnus, I put up my binocs to where I thought it would be - et voilà! First attempt to locate it. All 10 stars easily seen. Went back to Cygnus to locate Albireo to use it as the start point to locate the Coathanger. Put my binocs up to find it then went 45º downwards and located it again. Tony Schellinck taught me well!
Delphinus

Instrument: Binoculars, 10x30 IS
S&T Chart Reference: 52, 54
Used Corona Borealis to locate M13 with binoculars. Grey fuzzy was easily seen between η Hercules and ζ Hercules.
After a short sleep we were once again the go getting ready to take down camp when Jerry noticed the waning crescent Moon. Almost missed it against the clear blue sky. Read more about it at Explore the Moon (Binocular) - July 20, 2017.

Travelling by bus from Ottawa to the Diefenbunker, I noticed the Quarter Moon high in the sky. I couldn’t make out any details other than the fact it was a 1/4 Moon.
I took out my binoculars and attempted to look at the terminator. Despite the image stabilization feature of the binoculars, the bus bounced too much to get a good look. There was no time to look at the Moon when we arrived and when we came out of the Diefenbunker it had clouded over. No Ottawa Star Party at the Ottawa GA.

Clear skies with only a few clouds. No wind. A few fireflies in the greenery near the shore. While Jerry was setting up his time lapse equipment, I was getting my bearings and determining the stars that rose in the night sky visually first.
However, my first order of business was to look at the Moon while it was still up high enough above the tree line at SCO. Not much time for Explore the Moon (Binocular) - June 26, 2017.
M70 |
|
10:00 PM Given sky conditions on any given night, we appreciated that only one of these methods might be used. Tonight's excellent seeing and transparency meant both could successfully be used. |
10:10 PM
For the second time in a month, Scorpius was well above the horizon and at about a 45° angle in the sky. θ and η were about 5° to 10° above the horizon; this was the brightest and highest I can recall seeing this constellation at home in Nova Scotia!
Adjacent to Scorpius was the Teapot (the asterism in Sagittarius). It, too, was at about 5° to 10° declination and was completely horizontal! Ascella and Kaus Borealis were level with the horizon and Kaus Borealis pointed straight up. Never saw it level before. Came close in Utah. All stars within the asterism were very easily located and identified.
10:15 PM - 10:26 PM
According to SkySafariPro, Jupiter was located in Virgo. Located Spica. Jupiter was bright and at a similar declination to Spica. Virgo seemingly wrapped her arm around the planet. Saturn was also visible this evening. Found Saturn adjacent to Antares in Scorpius.
10:42 PM
I noticed a satellite going across my visual field from West to East. My phone identified it as Taingong.
11:02 PM
Was looking in the general area of Virgo when an iridium flare caught my eye travelling SW to NE above Spica towards Jupiter.
11:16 PM
With the Teapot so high and level against the horizon, it was easy to find M6 (Butterfly Cluster) by going 1.5 FOV from Kaus Borealis.
11:18 PM
I decided that given Spica was so bright, I would use my S&T Pocket Atlas to identify the other stars in this constellation.
Not disappointed!
a) 109, τ, &mu:, and Syrma/ι were the first stars in addition to Spica that I could see.
b) Next came ξ, Vindemiatrix, Porrima. Vindemiatrix was particularly bright.
10:30 PM
Started at Kaus Borealis and followed a line to the midpoint in the spout, then the same distance to M8. M20 was just a little above M8 in the same FOV. This was not difficult to find given the excellent sky conditions.
10:37 PM
Could see all the stars in the Big Dipper naked eye; did not use binoculars. Polaris was easily found using the Dipper's pointer stars. I did not attempt to find Ursa Minor stars this evening.
11:28 PM
I knew Delphinus was near Altair and Cygnus. Found the stars naked eye but it did take a while to locate all 5 star. When I tried using my binoculars, there were too many stars for these untrained eyes to single out the 5 stars of Delphinus.
11:38 PM
I turned around toward the Warm Room and storage shed to see Cassiopeia and 3 of the 4 stars in the Square of Pegasus. I visually drew a line from Schedar towards Alpheratz and guessed where M31 was located. I was lucky in that I found it as soon as I held up my binoculars. The oval shape of the Galaxy was grey with a slightly brighter centre. I did not look for the remaining parts of Pegasus at this time.
12:02 AM 12:05 AM |
1:40 AM NOTE: Later on June 27, 2017, Dave Chapman told us M11 is sometimes referred to as the "golf ball" as some of the stars adjacent to it seemingly form a "golf club". In reviewing the photos Jerry took earlier, we were easily able to identify both the ball and the club. Note that the club is upside-down so to speak. |
Phase: Waxing Crescent (10.4%) Location: St. Croix Observatory (SCO) Moonrise: 8:28 AM Moonset: 11:13 PM |
Cloudless night. When we arrived at SCO, the sliver of a Moon was peeking through the evergreens. There wasn't much time before it disappeared. I was able to find Mare Crisium (the western shore still in shadow at the terminator), Cleomedes, the Gang of 4 and several other craters in the lower segment of the crescent. The remaining surface of the Moon was dark but the 'full' Moon could be seen (Earthshine). When it disappeared, I went on to general observing. Here are the notes for General Session - June 26-27, 2017. |

At some point in the later portion of the observing session, I noted how easily the Summer Triangle could be seen - Deneb in Cygnus, Altair in Aquila and Vega in Lyra. After finding the stars of the Triangle, I then looked at their related constellations briefly.
1:38 AM
I was able to locate the Keystone of Hercules using the Corona Borealis as the pointer. Looking between η and ζ Herculis, I found the small grey fuzzy known as M13, a.k.a. the Hercules Cluster. Couldn't make out the star field definition.
1:47 AM
Could only find Polaris, Pherkad and Kochab in Ursa Minor. Could not find the other stars either naked eye or with my binoculars.
1:57 AM
From Albireo, I went 1/2 FOV and found the Coathanger. All 10 stars of the asterism were easily found.
2:02 AM
In Cygnus, I followed the stars from Deneb down to Albireo. Although I could find the two stars of Albireo in my binoculars, I couldn't distinguish the blue and yellow.
2:10 AM
Jupiter was easily identified. I found it basically at the same declination as Arcturus. It was quite bright! Didn't make note of the location of its 4 moons.

I looked westward out our bedroom window to see a sliver of a Moon hanging just above the treeline, with a bit of a rough edge on the terminator. Grabbed my binoculars and ran outside only to find the Moon had disappeared. I went back in thinking I was too low to see it in the backyard, only to find it had disappeared from View. So much for viewing it. :( Following this session, I went back in the house for a few hours. I went back out in the wee hours of the morning to continue observing other celestial bodies. Look at General Session - June 25-26, 2017. |
Lunar Phase: Waxing Gibbous (89.2%) Moonset: 5:39 AM CDT Moonrise: 7:02 PM CDT Location: Sandy Beach Campground, Iowa (near Cedar Rapids) |
Very clear skies, no cloud. Amazing night! We had frozen the night before in the Rocky Mountains but on this evening we wore shorts and t-shirts to watch the night skies evolve. Set up our camp chairs next to the tent in the open field and enjoyed watching the Moon rise. Earth's Shadow and the Belt of Venus were bonuses. The fireflies in the field’s hedging that spread before us and along the river's edge twinkled like mini-Christmas lights.

On one of the evenings while staying in Moab, Utah, I drove to the Dead Horse Point State Park to take in the sights from the elevation. While at the Grand View Point on the park, there was a beautiful panorama of the Earth's Shadow and the Belt of Venus. A father and son were taking time-lapse of the view but had no idea what they seeing. They thanked me for explaining the colour change that they attributed to clouds and they couldn't wait to process their video. The Colorado River is below (centre). In the back left rising above the landscape are the La Sal Mountains; unfortunately, the roads into the mountains were closed due to construction when I was there. The square pools of water seen in front and below the mountains are potash drying pools.
I left Grand View Point as it started to get dark. Not sure I wanted to drive the narrow winding road in the dark, especially with the possibility of not seeing cattle on the road in time.

I had made arrangements with Red Rock Astronomy to have a sky tour while in Moab. Alex, the proprietor, set up in a small, elevated, open field. Absolutely incredible 360° view of the land around us from our location. It was such an "oh wow" moment to see astronomical objects almost at eye level and to see them so far above the horizon, especially Scorpius! And the stars were so pinpoint!
Alex was showing the group several objects in the night sky through his telescope, proving information about and at times the associated star lore. Because of the number in attendance and the time he allotted for the session, participants only had 15 seconds at the eyepiece. I had this brief view of M44 (Beehive Cluster).
|
Jupiter Time: 10:12 PM Instrument: Telescope The planet and its 4 Moons were so so clear! Could even see the Red Spot! |
Scorpius Time: 10:20 PM Instrument: Visual + Telescope S&T Chart Ref: 56, 58, J I was paying attention to the Big Dipper and watching the stars come out as the sky darkened to identify Polaris. I literally turned around on the spot I was standing and there was Scorpius in all its glory completely above the horizon! Every star in the constellation was found and were very bight and non-twinkling against the night sky. Theta (θ) and Eta (η) were above the horizon at approximately 20° declination. It was so exciting to see!! No words could describe how amazing it was to see this constellation so high in the sky compared to what we see in Nova Scotia. |
Teapot in Sagittarius
Time: 10:10 PM
Instrument: Visual
S&T Chart Ref: 66, 67, 68, 69, I
I was excited, thrilled, in a state of disbelief to see the Teapot with Ascella and Kaus Australis almost horizontal and at 20° declination. I have never seen it so high nor so clear and bright against the dark sky. Incredible! Couldn't help but stare at it for several minutes while Alex set up his telescope.
We were on our way to Moab, Utah for Jerry to attend Ron Risman's 4-day time-lapse workshop. En route, we decided to camp at Mesa Verde National Park in New Mexico. It was an interesting to go to the cave city and visit the site where people lived halfway up from the Valley and half way down from the top of the mesa. They had to climb up or down with food, water and all other things needed for their village to thrive and to build. Interesting history told by a Ranger who just loved this park and who declined offers to move to other national parks. |

I was able to find all the stars within Leo. Denebola was the star that initially caught my eyes on the way back from the Ranger talk
12:00 AM
Looked at the sky from the campsite itself. Clear skies until clouds moved in later in the AM.
Noted Altair, Alshain, Tanazed and Delta; didn't look further along the constellation to find the remaining stars. Arcturus was very bright against the dark skies. Able to visually locate all the stars in Lyra. Located Scorpius (original notes taken were not detailed).
Jupiter also located in Virgo near Porrima.
I found the Teapot. I looked up from its lid star (Kaus Borealis) at a 45º angle. I found the little "Y" star formation using the binoculars and just past it was the little fuzzy known as M22. I then started at Kaus Australis and extended an imaginary line to Kaus Media. I used the binoculars to find M224 twice that distance above Kaus Media.

Clavius:
A large, dark centred crater at the south end of the terminus; much smaller craters south of Clavius.
Tycho:
Didn't see the rays you see during the Full Moon or later in the Moon's cycle. It looked like a flower - Tycho was the centre with smaller craters circling it like petals.
Eratosthenes:
The Apennine Mountains in their entirety could be seen this evening. This crater was at its southern tip. Quite large with a central peak.
Plato:
Located on the NE shore of Mare Imbrium. Large, dark centre with well-lit jagged rim.
Located Mare Nubium.

Winter Circle At 6:45 PM, Orion couldn't be easily seen because of the brightness of the Moon. At 8:15 PM, it was very visible. All the stars of the Circle were clearly and easily viewed - Capella, Aldebaran, Rigel, Sirius, Procyon, Pollux, Castor. NOTE: The night before, I could only see Pollux, Capella, Aldebaran and Sirius due to the thin cloud cover and the First Quarter Moon. |
|
Winter Triangle Time: 9:16 PM Instrument: Visual Dave Chapman had emailed the Halifax Centre Discussion List to remind us there was also a Winter Triangle - Procyon, Sirius & Betelgeuse. Tonight this asterism appeared to be an equilateral triangle. |

|
Visual: Thin cloud plus perhaps the First Quarter Moon made for poor visibility of the Winter Circle but was able to see some of the stars around the Moon plus the adjacent Pleiades. NOTE: The dark line across the image is not an astronomical feature; it was the line drawn between this sketch and the one above. |

This session began with looking for objects in the RASC Explore the Moon (binocular program). I then went looking for constellations and DSOs. The First Quarter Moon was centred in the Winter Circle, but was able to identify some of the brighter stars - Pollux, Capella, Aldebaran and Sirius.
M45 (Pleiades) Time: 9:25 PM Instrument: Binoculars 10x30 IS Thin cloud and First Quarter Moon limited visibility but was able to see the 5 brightest stars of the Pleiades.

An incredibly clear night. Clearer than we have seen in quite a while. Didn't look for M36, M37 or M38 in Auriga. Found an interesting fact online later this evening: this is the site of the anti-Galactic Centre (opposite centre of the Milky Way).
Leo - Sickle Asterism The exciting moment for me this evening was the discovery of Leo over the rooftop of our home. I wondered what the semi-circle of stars were part of anything or whether it was wishful thinking on my part. Come to find out through SkySafariPro that what I was seeing was the sickle. The others stars of the constellation (including Denebola) were hidden by the house. When I attempted to find the constellation on another side of the house, the street lights obscured my view. However, I did clearly see the 5-star sickle asterism that ended in Regulus (α Leo). |

Auriga Time: 8:45 PM Location: SCO Instrument: Visual S&T Chat ref: 12 Capella was easy to find in the Winter Circle. The other 5 stars of the constellation were easily visible with naked eye. This constellation wasn't difficult to find regardless of where in the sky they were located. |
|
Canis Major Time: 8:52 PM Location: SCO Instrument: Visual S&T Chat ref: 7 Didn't look for M41. Sirius was easily detected. From Sirius, I found Mirzam and Adhara. Wizen and Aludra took some time to find naked eye but were eventually found. Didn't find the other stars of the constellation (marked as an 'x' in the sketch). |
|
Cassiopeia + Kemble's Cascade Time: 9:00 PM Location: SCO Instrument: Visual S&T Chat ref: 1, 3, 72 Easily identified all 5 stars visually. used it to locate Kemble's Cascade. Didn't sketch them. |
Hyades (Melotte 25, Collinder 50, Caldwell 41) |
Winter Circle Time: 10:12 PM Location: SCO Instrument: Visual At 8:15 PM, a little cloud cover in the SE soon dissipated to once again reveal Orion and Canis Major. Came back out at 10:15 PM to clear skies and -7° C. The winter circle was so clearly identifiable this beautiful clear night. I was so excited about seeing the circle that, other than Orion and Leo, I didn't locate stars in the other constellations that were so high in the sky. Missed opportunity initially. After observing the Moon-Venus-Mars conjunction, I identified stars in 6 constellations: Orion, Gemini, Auriga, Canis Major, Taurus and Canis Minor. NOTE: Canis Minor couldn't be made out despite Procyon being very visible. |

Now that the sun was up, the features were somewhat bright but not completely washed out. Drew some of the features I saw but I obviously did not make much attempt at identifying them other than Posidonius and Tycho. At this point, I was getting used to the newly acquired 8" Meade SCT "push-to" telescope. With the star diagonal, I was sometimes confused as things were not only backwards (as they should be) but felt as though sometimes they were backwards and upside-down. Don't ask - I can't explain.

This was a surprise! A discovery in our own backyard! Facing the downhill neighbour's yard, I noticed a very bright star. It didn't appear to be associated with other stars or constellations nearby. SkySafariPro identified the bright star as Fomalhaut in the constellation Pisces Audtrinus. I then looked up the constellation and could identify 7 of the 10 stars comprising the constellation; the other 3 were hidden by the neighbour's trees.

No breeze and only the occasional cloud. Fog rolled in from the west and by 11:00 PM the observing session ended. NOTE: Attempted to find M5 located north of Zubeneschamalli but couldn't due to the fog.
Libra:
Time: 10:30 PM
Looked for Scorpio's Antares and Delta (δ) to get an orientation to begin looking for Libra. I was looking for α (Zubenelgenubi) and β (Zubenschemali) and found them readily, then began looking for other stars within the constellation. Was delighted I could find all of them and that the "weigh scales" were so easily recognizable! Once found, I could find them again using naked eye.
M13 (Hercules Cluster):
Time: 10:36 PM
M13 was readily found next to the Corona Borealis; however, the sky was such that locating and seeing M13 was not possible visually or with the binoculars. Disappointment.

Obtained a ride from Dave Chapman and Chris Young to head off to SCO whereas hubby headed to St. Margaret's Bay for a timelapse session. Windy at first at SCO and then stopped.
M4: (NGC 6121)
Time: 9:45 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 56, 58
Chris Young provided guidance on how to find it. Antares was located low in the sky with Mars and Saturn nearby. The grey circular fuzzy was seen with averted vision at approximately 5 o'clock from Antares.
M20 & M21:
Time: 9:45 PM + 11:37 PM ADT
Equipment: Binoculars 10x30 IS + Thurlow Binoculars
Magnification: x10 + x20
S&T Chart Ref: 67, 69, I
Initially used my binoculars but then used the Thurlow Binoculars with Chris Young's assistance. We were able to clarify the boundaries between M20 and M21. It was much easier with the Thurlow's x20 magnification to make that distinction.
Boötes:
Time: 9:52 PM ADT
Equipment: Visual
S&T Chart Ref: 42, 44, 53, 55
Thanks to Chris Young for identifying this and showing me how to find it by following the arc of the Big Dipper's handle ("arc to Arcturus") then looking for the necktie/kite shape of the constellation. Noted it was adjacent to Corona Borealis and was tilted away from it. Identified stars in the constellation.
M22, M24, & M25:
Time: 10:22 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 67, 69, I
Chris Young and I wanted to get a better sense of location, size and boundary in relation neighbouring Messier objects. We found all 3 objects with our binoculars and had no difficulty in doing so.
To find M22:
It was easy found with Kaus Borealis at about 5 o'clock in the boundary of my FOV, then moved the eyepiece a little NE to view a small Y-shaped asterism with M22 to the left of it. The circular cluster was denser in the centre and fairly bright. Didn't draw the stars in it.
To find M24: (Sagittarius Star Cloud)
Time: 10:40 PM ADT
Equipment: Binoculars 10x30
Magnification: x10
S&T Chart Ref: 67, I
We followed the line from Kaus Australis to Kaus Media in the Teapot, then went up 2 twice that distance. We saw a very dense star field that I couldn't fit not 1 FOV.
To find M25:
Time: 11:10 PM ADT
Equipment: Binoculars 10x30
Magnification: x10
S&T Chart Ref: 67, I
Found a dim patch of diffuse light. Couldn't make out individual stars very well at all. Thanks Chris Young fo helping locate this one!
Lyra:
Time: 11:00 PM ADT
Equipment: Visual + Binocular 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 63
Thanks to Chris Young! Located Vega then the parallelogram below it visually. All 4 stars of the parallelogram were easily identified but they were pale compared to Vega.
Lyra, Epsilon1 and Epsilon2:
Time: 11:00 PM ADT
Equipment: Binocular 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 63
Chris Young and Dave Chapman then wanted to show me Epsilon1 and Epsilon2 using binoculars and SCO's 16" reflector telescope.
a) Binoculars: Looke for Vega then moved to Epsilon. Separation was evident albeit blurred.
b) Telescope: Found it in the finder scope, then had to move it slightly to see the "double-double". The pair on the left was horizontal; the pair on the right was vertical.
Lyra, Zeta1 and Zeta2:
Time: 11:10 PM ADT
Equipment: Binocular 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 63
Found the triangle earlier in the evening with binoculars. Zeta1 and Zeta2 were not sen with binoculars but were viewed wth the telescope. First found it in the finder scope then slightly adjusted it for the eyepiece.
Ursa Major - Alcor (79 UMa) & Mizar (80 UMa):
Time: 11:15 PM ADT
Equipment: Binoculars 10x30 IS + 16" Newtonian Reflector with 8mm eyepiece, f1800, x225 mag
S&T Chart Ref: 42, 44, 53, 55
a)Visual: Found Mizar and Alcor plus a 3rd faint star to the left that would form a triangle, just as I had seen the night before eat the Swiss Air Monument.
b) Binoculars: Found the 2 stars plus a dimmer smaller star to their left to forma triangle.
c) Telescope: I was shown Mizar in the telescope, then was made to find Mizar A and Mizar B using the telescope without the go-to capability. I was able to find them; they were close together with Mizar B located about 4 o'clock to Mizar A.
Kemble's Cascade:
Time: 11:30 PM ADT
Equipment: Visual + Binocular 10x30 IS
Magnification: x10
S&T Chart Ref: 11, 13
Thanks to Dave Chapman who introduced this to me.
a) Visual Location: Found Cassiopeia. Drew an imaginary line from Beta to Epsilon, then extended the line the same distance from Epsilon. Saw a faint bright line extending southwards towards the horizon.
b) Binoculars: Put my binoculars up to see what I thought was the start of the Cascade. Saw 4 bright stars in almost a straight line then the multiple well-spaced stars in a cascade towards the horizon and then terminated in stars arranged like the end of a hockey stick. A much brighter star half way down.
Capricornus - β1 & β2, δ1 & δ2:
Time: 11:40 - 11:50 PM ADT
Equipment: Visual + Binocular 10x30 IS
Magnification: x10
S&T Chart Ref: 66, 68, 77
Dave Chapman agreed to help me find the two sets of double stars in Capricornus - Delta1 and Delta2 plus Beta1 and Beta2. We found the constellation visually then located Delta Capricornus that appears as a single star. However, with binoculars, 2 stars (optical double) appeared with one just slightly above the other. We then looked below them for Beta Capricornus (Dabih). Again 2 stars were visible at this location, one brighter than the other. I failed to draw or explain in my rough notes the relationship of these two stars.
M57: (Ring Nebula)
Time: 11:47 PM ADT
Equipment: SCO Skywatcher 16" Dobsonian, 8 mm eyepiece
Magnification: x225
S&T Chart Ref: 63
Couldn't see this visually with binoculars. The telescope showed a donut-shaped object, more dense on the outer edge and less dense as went closer to the centre opening. NOTE: Also saw this Aug 26/16 at Nova East using mark Dryden's Obsession telescope.

Clear sky with only a light wind. First Quarter was 3 days ago at 8:50 AM
Moonset: 2:02 AM Moonrise: 4:58 PM
Sunrise: 6:50 AM Sunset: 7:30 PM
Mare: Mare Hurmorum, Mare Iridum
Craters: Copernicus, Encke, Gassendi + Gassendi A Kepler, Lansberg, Plato, Reinhold, Tycho
There was a large protuberance on the terminus in the area of Mare Iridum. I could not identify the lunar feature that would have been illuminated so well. Maybe the Jura Mountains? |
Lunar Phase: 1st Quarter (46.6%) Location: Home |
The evening began with the First Quarter Moon visible above the trees. This evening is to be devoted to Moon watching but will look at constellations and DSOs when we can do so. Jerry has the Meade LX200 set up with his camera so this session for me is through two pairs of binoculars - 10x30 IS and 15x70.
9:00 - 9:30 PM:
Reinforced ability to view the following seas: Crisium, Fecunditatis, Serenitatis, Tranquilitatis.
New to my observations tonight were:
a) Mare Vaporum
b) Mare Frigoris & Lacus Somnorium
c) eastern portions of Mare Imbrium
d) Alps Mountains on the north shore of Mare Imbrium
e) Could make out the line of the Apennine Mountains running SW to NE at the bottom of Mare Imbrium and north of Mare Vaporum
f) Could make out the large, oval-shaped crater Petavius on the southern border of Mare Fecunidtatis.
g) Cleomedes was visible above the north shore of Mare Crisium. It wasn't attached to the Mare.
h) Oval-shaped Posidonis was seen on the shore between Mare Serenitatis and Lacus Somnorium.
i) Just south of the Alps were the following craters: i- Cassini ii- Aristillus iii- Autolycus (the smallest) iv- Archimedes (the largest) |
|
j) Sinus Medii below which I could easily see the following craters (top to bottom): i- Herschel ii- Hipparchus iii- Halley iv- Ptolomaeus v- Alphonsus vi- Arzachel |
|
9:30 - 9:45 PM: Could see the crater Plato on the terminus. It was bright on the rim (western edge) whereas most of the crater and its eastern edge were in shadow. |
9:45 - 10:00 PM:
My focus was the lower quadrant, trying to identify, if at all, the "Gang of Four" craters. I am quite sure I found Vendilinus and Petavius. If I identified Furnerius, it was the centre of a feature that looked like a mini-Tycho. Was not sure about Langrenus. All the craters were whiter than the surfaces around them; no ridges were detected by shadows.
10:00 - 11:00 PM:

Temp: 16° C - 12° C
Fog and cloud on the low south horizon. Sitting on the rocks with Jerry as he does his astro-imaging and we do some visual observations together. As we were setting up for time-lapse imaging and binocular observing respectively, we watched the crescent Moon go down.
Meteors
Time: 9:00 PM - 1:00 AM ADT
Equipment: Visual
Saw 12 throughout the night. No Moon. One lasted 1-2 seconds, quite bright.
Satellites
Summer Triangle (astronomical asterism) Located the brightest stars in Cygnus, Lyra and Aquila - Deneb, Vega and Altair respectively. |
|
Boötes Time: 8:45 PM ADT Equipment: Visual S&T Chart Ref: 42, 44, 53, 55 Located the Big Dipper then arced to Arcturus to locate and identify the stars in this constellation. |

Ursa Minor
Time: 8:50 PM ADT
Equipment: Visual + Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 41, 51
No low clouds but occasional high clouds impeded the view. Located the North Star (Polaris) then followed the stars to the bucket. I could easily see Zeta, β and Gamma UMi but not Eta UMi. This was the second night I had difficulty seeing it.
Cepheus (The King)
Time: 8:53 PM ADT
Equipment: Visual
S&T Chart Ref: 71, 73
Found between Cassiopeia and Cygnus, adjacent to Polaris. I knew Cepheus' roof pointed towards Polaris, so began my visual search near Cassiopeia and Polaris. Found it! I only looked for the stars that were brightest and formed the "house". Must look for other stars on a clearer night and when light pollution is not a factor.
NGC 869 / NGC 884
Time: 9:08 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 1, 2, 13
Viewed this with Jerry. Confirmed I knew how to find the double cluster.
Sagittarius
All stars of the Teapot were easily seen above the clouds on the horizon. Mars, Saturn and Antares were in close proximity.
M7: (Ptolemy Cluster, NGC 6475)
Time: 9:18 PM
Equipment: Visual
Magnification:
S&T Chart Ref: 58, 67, 69, I
Easily found it visually as a very large and bright object with direct vision and even brighter with averted vision. Although close to Scorpius, found it easier to find using the Teapot. Numerous stars with very bright core and those outside the core were equally as bright. Not as resplendent as the Pleiades - but close!
M8: (Lagoon Nebula)
Time: 9:27 PM
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 67, 69, I
Started at Kaus Australis and continued to the mid-point of the spout, then an equal distance again to M8 (or extend the line from the spout 2 FOVs). A line of 5 bright stars highlighted the object and its oblong shape. Through binoculars, I could see the brightness and the grey of the surrounding stars. In same FOV as M20.
M20: (Trifid Nebula) Started at Kaus Australis in the Teapot and continued to the mid-point of the spout, then an equal distance again to M20. In same FOV but just slightly above M8. The stars didn't appear as bright as those in M8. Looked like the brighter stars formed a shape similar to M13 then had a large grouping just off-centre. Star field looked somewhat circular and a fuzzy grey. |
M21:
Time: 9:27 PM
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 67, 69, I
Found M20 and M21 in close proximity and in same FOV. Given their proximity, wasn't sure that both were seen versus only M20. There was a small greyish, mottled area NE of M20 that led me to believe I did see it. Couldn't discern bright stars in M21 as I had in M20. I didn't sketch it.
M13: (Hercules Cluster)
Time: 10:13 PM
Equipment: Visual + Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 52, 54
Found Corona Borealis then the Keystone of Hercules then M13 with direct vision then with the 10x30 binoculars.
M45: (Pleiades)
Time: 11:00 PM
Equipment: Visual + Binoculars 10x30 IS
Magnification: x10
S&T Chart Ref: 14, 15, A
Because of the light pollution towards Halifax, we had to wait until it was higher in the sky to observe (~ 60°). Used averted vision to view it brighter in the sky than seen by direct viewing. Binoculars allowed viewing of the brighter "sisters" and "parents" with some of the secondary stars within. Viewed this at 11 PM and again at 2:05 AM.
Triangulum:
Time: 11:00 PM
Equipment: Visual
S&T Chart Ref: 2, 4
Confirmed I knew how to find the constellation as taught by Dave Chapman. Due to light pollution from Halifax, had to wait until it was higher in the sky to observe.
Pegasus & Square of Pegasus
Time: 12:22 AM
Equipment: Visual
S&T Chart Ref:74, 75
I located the Square of Pegasus using Cassiopeia and Andromeda as markers. I was able to see the stars o fate Square, plus some of the other stars of the constellation, but not all. I think I found Enif.
Aquila: (The Eagle)
Time: 1:18 AM
Equipment: Visual
S&T Chart Ref: 64, 65, 66
Sitting and looking at St. Margaret's Bay, I remembered Chris Young saying Altair was in the Eagle (Aquila). This evening, Aquila with its adjacent stars β and γ (gamma) were evident. Looking at SkySafariPro, we determined the location of the other stars in the constellation. We were pleased/thrilled that we were able to find the 3 stars in the head of the Eagle as well as θ (theta), λ (lambda), δ (delta), and ζ (zeta). Didn't search for Eta or Iota (another time?).
Phase: Waxing Crescent (7.2%)
Location: Swiss Air Monument

Equipment: Visual
Seeing: not recorded

Jerry and I were setting up for time-lapse imaging and binocular observing respectively. We watched as the crescent went down below the horizon as a red-orange sliver. Absolutely breath-taking and so amazing at how quickly it "disappeared" at the horizon. Took a picture of it but Jerry deleted it when formatting the card for time-lapse.
Location: Swiss Air Monument, Peggy's Cove, NS

Fog/Cloud on the horizon impacted viewing lower parts of Scorpius and the Teapot.
I found M8 by going up the midline of the spout from Kaus Australis. M20 was at the top of the FOV with M8. Stars were not as bright s those in M8. It appeared the 4 brightest stars formed a mini-Keystone of Hercules, then had a large grouping just off-centre. The star field looked somewhat circular and a fuzzy grey. Could not discern the dark lanes that are characteristic of this nebula.

Fog/Clouds on the low horizon initially but they disappeared by 10 PM. 12° C - 16° C. Lights from Halifax/Bedford restricted viewing until objects were higher in the sky. Only made reference to M7 in my notes as a large open cluster framed by several bright stars with numerous less bright/smaller stars within.
|
Ursa Major Only stars of the handle were visible at 8:30 PM. By 8:45 PM the bowl was visible as was Polaris in Ursa Minor. The double stars of Mizar and Alcor were easily seen naked eye and with my binoculars. |
Coathanger / Collander 399 / Brocchi's Cluster Started at Albireo at the top of my FOV then moved another .5-1 FOV and there it was! Could easily put my binoculars up there afterwards and land on or near it. Can also be found 1/3 of the way between Altair & Vega. NOTE: NASA refers to this as an asterism. |
|
|
M31 (Andromeda Galaxy) Found it using the square of Pegasus and its "Andromeda legs". Confirmed faint fuzzy as M31 using my binoculars. An elliptical shape with a bright core and less bright star field around the core. |
M45 / Pleaides / Melotte 22 / "7 Sisters" This wasn't the first time I found the Pleaides, but this was the first time it was so visible and therefore easily seen naked eye. I am always impressed with this open cluster and its beauty. The 7sisters and their parent were very bright with numerous stars surrounding them. It always reminds me of a distorted, shrunken Big Dipper - shorter handle (1 main star) and a smaller squashed bucket. |
Triangulum Time: 11:40 PM ADT Equipment: Visual S&T Chart Ref: 2, 4 Look for Andromeda (M31), then find the constellation below Mirach and Almach. Thanks again to Dave Chapman! With naked eye, the 3 brightest stars were very visible and stood out in the dark sky. Delta Triangulum and 7 Triangulum were not seen visually; hope to find them another night. |
NGC 869 / NGC 884 Thanks to Art Cole for instructions on where to find the double cluster. Both clusters are easily discernible within the same FOV, one just above and to the right of the other. Diffuse field around a bright centre for both NGCs. Found them between Ruchbah of Cassiopeia and Miram of Perseus. I was impressed - very cool! |
Capricornus
Time: 12:30 AM ADT
Equipment: Visual
S&T Chart Ref: 66, 68, 77
Capricornus is located beside Sagittarius outside the Milky Way midway to the Square of Pegasus. Looked like a double "V" - both very broad at the opening with the lower one being much deeper than the upper. Reminded me of a painted clown smile. The constellation also had many stars inside of it. Will have to take a closer look through binoculars.
Thanks to Dave Chapman! He jokingly referred to this constellation as "Orion's underpants." (NOTE: Zits cartoon in 2018 referred to it as "Orion's fanny pack.")

Constellation: Taurus This wasn't the first time I found the Pleaides but it was the first time it was so easily visible in the sky. I am always impressed with this beautiful open cluster! The 7 main "sisters" and their parents were very bright with numerous stars surrounding them. It always reminds me of a shrunken Big Dipper - shorter handle (1 main star) and a smaller squared bucket.* * Roland, an astronomy friend from out West, described the Pleiades as a "shopping cart." I like his descriptor better than my "shrunken Dipper." |
Conjunction: Saturn - Mars - Antares / Venus - Jupiter with "green flash"

Dr. Roy Bishop had organized with a local farmer to use the farmer's driveway and adjacent field for viewing. A group attending Nova East drove 5 minutes outside Smiley's Provincial Park to the farm with a direct view facing West.
A partly cloudy sky with wide expanses of clear sky. Warm evening with the sky at the horizon in beautiful orange/peach shades. South of the sunset were Saturn with Mars (@ 7 o'clock to Saturn) and Antares (directly below Saturn and @ 5 o'clock to Mars). The two planets and star were extremely bright and other deep-sky objects also shone brightly (I didn't observe the DSOs).
Venus and Jupiter were visible then briefly covered by clouds before coming back into glorious view. Venus was exceptionally bright and positioned almost directly above a smaller and less bright Jupiter. We watched as the two planets lowered into the horizon - first Jupiter, then Venus. Gem of the night was seeing the ever so brief green flash of Venus at the horizon.

-6° C, clear skies. An amazing clear night! With seeing so well, I wanted to determine which of the stars in the constellation could be seen naked eye. Didn't look for M35 at the end of Castor's foot. Couldn't make out the "arms" but the legs were seen after several seconds of looking and blinking (Mebsuta, η (eta), δ (delta), μ (Mu), Mekbuta, ζ (Zeta), and Alhera).
Binoculars confused me because of all the other stars also visible, so I didn't spend any time using them.

Clear with occasional clouds. 12° C, humid with little or no wind. I attended Tony Schellinck's binocular table and found quite few objects.
M31 (Andromeda Galaxy) First up was finding Andromeda. By finding Cassiopeia, we used the arrow of the larger 1/2 "W" to find the constellation. He also showed us how to find it using the Square of Pegasus, going over two lines of stars, then going up the 2nd line to the 3rd "star" that's was kind of fuzzy - that was Andromeda. |

I followed Tony's directions to find Cygnus naked eye, then the directions on how to locate Albireo - the double star that I could see had a yellow-gold component and the other was blue. |
Tony's directions to find the Coathanger:
Locate Deneb, go down the neck of the swan (Cygnus) to Albireo. The Coathanger (aka Collander 399) is ~ 1.5 FOV from Albireo. By going down about 45° from Albireo, we would come down to an upside-down coathanger. This was really cool! It was very easy to see the upside-down hanger - 6 stars forming the straight line of the hanger with 4 stars forming the hook that curved towards the right. It was slanted at about 40° angle in the FOV. The hook began at the 4th star from the left. Thanks, Tony Schellinck!
He also showed us to find Vega in Lyra and the double-double of Lyra1 Epsilon and Lyra2 Epsilon.
Going towards the south end of the Milky Way, he pointed out Serpens, Scorpius and Sagittarius. After explaining two types of star clusters (globular & open) and nebula, he showed us how to find M8, M17, M22 and M25 in Scorpius along with M16 in Serpens and M6 & M7 in Scorpius.
M6 (Butterfly Nebula):
Time: 9:48 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 56, 58, 67, 69, J
The grey smudge appeared and was easily viewed. There are two ways to find M6:
a) Find Kaus Australis in the Teapot. Go to the right 1 FOV. Put that point on left of FOV and go right for 1/2 FOV. M6 should be in the middle of your view.
b) Take the distance from Theta (θ) to Kaus Media. Following the same direction, go 1.5 times that distance from Kaus Media.
M7: (Ptolemy Cluster, NGC 6475) Time: 9:48 PM ADT Equipment: Binoculars 10x30 IS Magnification: x10 S&T Ref Chart: 58, 67, 69, I Follow the base of the Teapot out 1.5 FOV from Kaus Australis. Large bright open cluster easily seen visually and very bright in binoculars. Multiple stars seen in FOV, some brighter than others. |
M13 (Hercules Cluster)
Time: 9:45 PM ADT
Equipment: Binoculars 10x30 IS
Magnification: x10
S&T Ref Chart: 52, 54
This was my 1st finding of M13. Tony Schellinck said to locate Corona Borealis to locate the Keystone of Hercules. M13 is located on the western side, approximately 1/3 of the way between Eta Hercules and Zeta Hercules. NOTE: Following the curve of the Corona also points to M13.

Used the Teapot in Sagittarius to find M6 (thanks to the directions provided by Tony Schellinck).
Started at Kaus Australis then went west 1 FOV. I put that point on the left at 9 o'clock then went west 1/2 FOV. M6 was centred in my binoculars. The grey smudge was easily identified and a few bright areas/stars were seen. There seemed to be a row of 4 stars near one border, a row of 3 stars below it, and a triangle of stars below that.

Tony Schellinck was teaching us how to star hop using our binoculars at Nova East Star Party.
I found M6 then went 45º to the right. The open cluster appeared with a few bright stars within it. Could also locate this visually by going east from Kaus Australis in the Teapot. What was especially noticeable was the line of 4 stars.

Aurora Borealis

We had heard the Aurora Borealis would be visible from the northern shores of our province so we headed to Hall's Harbour on the Fundy Shore.
Jerry set up his equipment for time-lapse as the colours would not be seen from our latitude. We couldn't see the vibrant colours but we could see the undulating pale cream bands on the northern horizon. They varied in brightness, height and distance from us. We were very excited to see the Aurora despite it being colourless. Our daughter and son-in-law who resided in Kentville area brought hot chocolate to us on the beach - very much appreciated!! The light on the pier did have some effect on the visibility.
NOTE: I did see a red-green Aurora while camping at Lake Superior Provincial Park in mid-July 1987. My brother and I sat up until the wee hours of the morning chatting and saw them overhead.

My first Star Party! Hubby found the RASC Halifax Centre Nova East Star Party online and was interested in going. After initially saying no to going with him, I changed my mind - after all, it was a camping weekend. On Saturday morning, there was a session that was well beyond my comprehension so I went to the observing field to listen to Paul Heath's Walk the Solar System. Along with the children in attendance, I learned a lot! Later that evening, Paul pointed out constellations and special stars in his Sky Tour. This was followed by Tony Schellinck's Binocular Table at which participants were given a pair of binoculars and showed several constellations, their special stars and the Messier targets in them. It was because of these two gentlemen that I was hooked on astronomy!!
Unfortunately, I did not begin to log my observationns until August 2015.
