Struve (100 miles) is another old lunar giant. Its walls are low and the vast floor is flat. It merges with Russell to the north and there is no wall separating the two. There are two 9 mile craters on the floor near the eastern rim. Under low light some low crests and a few craterlets are visible on the flooded floor.

Russell (64 miles) is Struve’s companion to the north. The walls are higher in the north and there is a well formed 14 mile crater on the eastern rim. Some small craters are scattered on the large flooded floor.

Eddington (80 miles) is another flooded crater. The walls are very low, except along the western rim against Struve. Parts of the rim are missing altogether on the south and east. The floor is smooth although there are a few low crests visible under a very low sun.
