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. |
