Clavius

This image is a LTVT reconstruction from a previously posted image of Tycho exposed 16 May 2011 03:08:08 UT through red filter. It shows Clavius in the middle. It is not readily visible because of a high sun angles and the rays of Tycho from the north.

This view shows a weathered surface characteristic of an old crater. It is 142 miles from side to side, and includes an area of at least 16,000 square miles within its irregular circumvallation. There are five large craters on the floor of Clavius, following a curve convex to the N., and diminishing in size from E. to W.  (http://the-moon.wikispaces.com/Clavius).

The lower image is another LTVT reconstruction showing both Tycho, above, and Clavius below.The high sun angle emphasizes the rays extending from Tycho.
