Unknown
Davy (35 km) crater is a small crater with a common format, but would not be quickly recognizable if it would not have had a strange crater at east called Davy Y.
On the southeast of Davy, is a small circular crater named Davy A.
Although these craters start the highlands, they are located on the Mare Nubium.
Davy Y (70 km), has a feature on its floor that extends beyond the crater, and continuing eastward, a perfect chain of small craters in a string column to the crater Ptolemaeus (153 km), which I find interesting because I have not met anywhere on the Moon such a kind of formation.
This chain of craters is called Catena Davy, and contains 23 craters which are likely to occured after a single impact with a body that disintegrated before impact. This chain can be seen dimly here, but I will look further observation with the telescope specifically.
The name Davy, was given after Humphry Davy (December 17, 1778 - 29 1829), who was an inventor and a chemist. It is best remembered for his discoveries of alkali metals, but also as contributions to the discovery of elementary nature of chlorine and iodine.
