I took advantage of decent morning seeing Thursday and Friday to make these two observational sketches. The edge of the South Polar Cap (SPC) is very irregular and a dusky rift can be seen in the cap. I've found the rift is best seen during late twilight or even after sunrise when the contrast effect is lessened. A morning limb arc was present in both observations. The dominant feature on the central meridian in both sketches is the classic albedo feature Mare Cimmerium.
