Abstract

Two days after first quarter, the Moon is showing the more pronounced roundness of the waxing gibbous phase along the terminator, as shown in Figure. 14.1 About 99 additional named features become visible on this lunation day. More of the western region of Mare Imbrium becomes exposed along with the jumble of craters in the western region of the rugged ancient southern highlands. Look at the incredible variety of crater shapes and the overlapping of so many craters and how that reveals the relative ages of neighbors in this fascinating and complex area. The selenographic colongitude on the ninth lunation day ranges from about 15° to 29°. We start today’s crater hop at the southwestern crater Newton.
