Franck Crater is to the south of the photo, to the north is Römer and its satellite craters with Römer T being the closest of it located north (Photo from the LRO)

This is a circular, bowl-shaped crater with a sharp rim that has not been significantly eroded. The interior walls slope down to the tiny floor at the midpoint. Just to the north of Franck is a joined pair of smaller craters, and the three nearly form a merged cluster of impacts.
