is a small
Lunar Crater that is located in the
Montes Haemus mountain range at the south edge of
Mare Serenitatis . It lies to the southeast of
Menelaus Crater . The irregular rim of Auwers crater has a gap at the north-northwest edge, which allowed
Lava flows to reach the crater floor and flood the interior.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Auwers crater.
