Another LROC image, M131623862L, was taken 2156 UTC on 19 June 2010 when the solar elevation was 8.4 degrees. The eastern rim of the crater did not cast a shadow at that time, indicating that the inner eastern wall is shallower than 13.1 degrees. At that time, the solar elevation and azimuth were 13.1 and 96.6. The pan was taken starting at about 106:58:27, which was about 0033 UTC on 31 July 1971.
