Ångström (crater)

Ångström is a small lunar impact crater located on the border between Oceanus Procellarum to the west and Mare Imbrium to the east. To the south is a formation of mounts rising out of the maria named the Montes Harbinger. To the east are some wrinkle ridges named the Dorsum Bucher and Dorsum Argand. This crater is bowl-shaped, with a circular rim and inner walls that slope down to the small central floor. It has a higher albedo than the surrounding maria.

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 Ångström crater.
