PYTHEAS
Directory - Section 20


BRIEF DESCRIPTION
The southern part of Mare Imbrium, bordered by the Carpathian Mountains (See section 31). Pytheas is a small lunar impact crater located on the southern part of the Mare, to the south of the crater Lambert. It has a sharply defined rim, a hummocky outer rampart, and an irregular interior due to slumping or fall-back. There is a small crater along the northern outer rampart, and a similar crater about 20 km to the west. The crater possesses a small ray  system that extends for a radius of about 50 kilometers. It is surrounded by lunar mare that is dusted with ray material from Copernicus to the south. Interesting objects for observation include a crater chain north of crater Stadius M at the bottom right of the map, and the "ghost" crater Lambert R, visible only when very close to the terminator. Refer to your copy of the Antonin Rukl lunar atlas chart, page 67.

Update 20130522 - Lunar impact of March 17, 2013. Fran Ridge, Coordinator of The Lunascan Project: "Robert M. Suggs, Ph.D, Space Environments Lead, NASA, advised me that the approximate impact location is 20.7 deg N, 23.7 deg W. The field of view of their telescope/camera system is large so a precise location is difficult to determine. Ned Haskin, then advised me that the impact appeared to be 10 degrees north of Copernicus (Section 31) 3 degrees west. Copernicus is almost centered on 10N 10W. This puts the impact area in Section 20, which is one section north of 31. The LAC/WAC images of the impact area are linked below under 'LRO Images'"
