First earthshine photography from lunar orbit, part SThe first photographs of the moon taken with earthshine illumination by the Apollo 15 crew were examined. Emphasis in the analysis was placed on a comparison of predicted exposures and obtained exposures. The results of the investigation indicate the following: (1) The predicted exposure of the maria areas and the obtained exposures were in reasonably close agreement. (2) The apparent-albedo values obtained for the floor of Aristarchus Crater are seven times greater than those for the maria.
