Observation 1 - April 17, 2019: R1: 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 dorsa on the very dark floor.
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.
