Wichmann is the small circular bowl-shaped crater in the lower right.
The large arc of sunlit hills is regarded as the rim of 62-km Wichmann R, on whose floor is 4-km Wichmann B.
Note: on the large greenish colored Rand McNally moonmap, the arc Wichmann R is called Leon hills. These hills were once known as Wichmann Gamma, Wichmann Epsilon, and Wichmann Theta (see chart SLC E5) (System of Lunar Craters, 1966).

Description


Description: Elger

(IAU Directions) WICHMANN.--This bright crater, about 5 miles in diameter, stands on a light area in Oceanus Procellarum, N.N.E. of Letronne and nearly due W. of Euclides. Some distance on the N.W. are the relics of what appears once to have been a large enclosure, represented now by a few isolated mountains.

Additional Information


Nomenclature


Leon hills

  • The arc of low mountains and hillocks N.N.W. of Wichmann (Wichmann R) is labeled the Leon hills on the large greenish colored Rand McNally moonmap and on the same map in Patrick Moore's Atlas of the Universe (1983). The origin of the name Leon hills is unknown (who was Leon?). Other mysterious names on these maps are online in the page Rand McNally. Research Danny Caes
  • Is this name (Leon hills) perhaps a derivation of J.Hewelcke's name Insula Lea? - DannyCaes Mar 12, 2016
  • Three sections of the arc Wichmann R seem to have received Greek letter designations: Wichmann Gamma (central part), Wichmann Epsilon (eastern part), Wichmann Theta (western part). Two additional parts to the east seem to have been known as Wichmann Alpha and Wichmann Beta. (see chart SLC E5) (System of Lunar Craters, 1966).
