R1: Davy is a circular crater with a central peak; its east and west walls looked collapsed. Davy A was round, sharp-rimmed and had impacted the SE wall of Davy.
R2: North of Davy were two craters - Mosting and Lalonde. They looked circular, sharp-rimmed and were closer to Flammarion than to Davy. Palisa was a crater that looked like it impacted the north of Davy Y but the wall between them was somewhat eroded/collapsed.


C1: The line of craters were seen at 9:40 PM viewing of this area. It began at Davy G, headed across the plain and terminated near Davy C.

NOTE: I came across these features quite by accident when searching for the Fra Mauro Formation. Catena Davy was so clear! I was quite excited because a friend had searched for and found it a night or two before and we could now compare notes.
