Unknown
In these astronomical photos by telescope is Grimaldi crater. It is the largest dark stain. These captured images from the wastern part of the Moon to terminal, are in sunlight, so it's all about dark spots and bright spots, not shadows.
According to the arrangement of pictures from top to bottom, Grimaldi gradually makes its appearance in the foreground. This crater has the appearance of a sea rather then a crater.
All features seen in this area have an oval shape because their positions on the Moon, but most are circular.
The other dark spot on the northwest of Grimaldi, is Riccioli Rima. A few miles south of Grimaldi, is Crüger crater (45 km). The most distinctive feature of this crater is the very dark floor, which is a crater with the lowest albedo features on the Moon. Lacus Aestatis (90 km) or "Lake of summer", is located northwest of Crüger.
