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. 

  • Crater A had impacted the SW wall.
  • Craters J and G were in line with A.
  • Crater G appeared to be the most shallow and elongated.

NOTE: Could also identify craters B & C adjacent to J & G.
