R1: Ejecta field around the crater but most of spray appeared to head towards Archimedes, almost reaching Feuillée and Beer. Only the east rim created a shadow on the east wall. Floor of Timocharis was completely visible. While the actual floor was small, walls were thick and ridged. The crater on its floor was quite visible but no evidence of a central peak.
