Crater Description
The immediate neighbors of the crater are the Volterra Crater in the northwest; Van Rhine Crater in the northeast; Campbell Crater in the east-southeast; Posi crater in the south-southeast and Bridgman Crater in the south-west [2] . Selenographic coordinates of the center of the crater , diameter 54.4 km [3] , depth 2.4 km [1] .
Over the long period of its existence, the crater has been significantly destroyed. The crater shaft is flattened, the northeastern and northwestern parts of the shaft are covered by noticeable small craters. the shaft height above the surrounding area reaches 1150 m [1] , the volume of the crater is approximately 2300 km³ [1] . The bottom of the crater bowl is flat, without noticeable structures, streaked with many small craters.
