No clouds over the nubile Mare Nubium tonight. I'm starting to get used to looking for things in Rukl's wackbards. Rimae Hippalus were quite evident and Rima Agatharchides was visible when the seeing was still. Sunlight was skating across Hippalus and showing a lot of very rough texture. A very interesting area in this light. The Hippalus Rimae look like they were caused by force pushing outward from the center of Mare Humorum. They roughly parallel the unidentified dorsum (dorsums, dorsumii, dorsumae?) in good Humorum.
