Blagg is a tiny lunar impact crater located on the Sinus Medii. To the east-southeast is the irregular crater Rhaeticus, and to the northeast lies Triesnecker. It is about 33 km to the east of the slightly larger Bruce. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
