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.
