The Lunascan Project presents
PTOLEMAEUS
Directory - Section 44

Updated 15 Oct 2011
BRIEF DESCRIPTION
The central part of the near-side of the Moon, with large walled plains. The dark surface of Sinus Medii, bordered by clefts, extends into this area from the north. This region, like that of Section 43, contains a network of valleys and clefts radiating from Mare Imbrium. The floor of the crater Alphonsus, the subject of a number of anomalies, was the crash-landing site of probe Ranger IX. Alphonsus is about 74 miles wide and the central peak about 1.5 mile high. Refer to your Antonin Rukl lunar atlas chart, page 115.

EARTH BASED TELESCOPIC IMAGES:
Since many EBTI's are not kept long on the internet is best to use Google for these images.
