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.
