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.

There were 10 Transits of Mercury (ToM) during Wurzelbauer’s life with one occurring during the year of his birth. Only the ToM of November 7, 1677 was visible in Europe from ingress to egress. Portions of the transits of May 3, 1661, November 4, 1664, November 10, 1690, November 3, 1697, and November 9, 1723 were also visible in Europe.
