Flamsteed is a small lunar impact crater located on the Oceanus Procellarum, which is named after British astronomer John Flamsteed.[1] It lies almost due east of the dark-hued Grimaldi, and north-northwest of the flooded Letronne bay on the south edge of the mare.
The rim of this crater is not circular in form, having a bulging rim to the southeast. The interior is relatively flat and undistinguished by impacts. The crater lies within the southern rim of a crater that has been almost completely submerged by the basaltic lava flows that formed the Oceanus Procellarum. All that remains of this feature designated Flamsteed P are some low ridges and hills arranged in a circular formation.
Flamsteed is a crater of Eratosthenian age.[2]
The Surveyor 1 craft landed within the northeast rim of the buried Flamsteed P feature, about 50 kilometers north-northeast of the Flamsteed crater rim.
Satellite craters
[edit]By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Flamsteed.
