What is "guericke"

Guericke is the remnant of a lunar crater at the north part of the Mare Nubium. To the north-northwest lies the large Fra Mauro crater, along with the co-joined craters Parry and Bonpland. To the east are the craters Kundt and Davy.

The surviving rim of Guericke has been worn, battered, and partly submerged by the basaltic lava that covers the floor. The wall is now little more than a circular series of ridges that join with rises that flow to the north, northwest, and south. The flooded crater remnant Guericke F is attached to the southwest exterior. The interior flood has a few small rises in the otherwise nearly flat surface. Two craters (Guericke D and H) mark the floor in the southwest quadrant.
