Crater-Hopping: Observing the Moon on Day 10,wn in Figure 15.1. We continue studying the rugged southwestern highlands. As we move toward the west limb, we begin to see the optical effects of foreshortening. The selenographic colongitude on the tenth lunation day ranges from about 28° to 46°. We start this day’s crater hopping at the southwest
