Well...This crater, located at 28N and 12E is actually the root of a famous controversy that started in 1866 when astronomer J. Schmidt said that it had vanished, and been replaced by a white patch. This observation is of dubious value because of the size of this crater, and because lunar observers Beer and Madler in 1868 it looked the same to Madler as he said it had done in 1832. Apollo photographs also give no evidence for any unusual features to this crater that could be interpreted as a recent alteration.
This isn't to say that things do not change on the Moon, only that this particular instance is not credible. For more information, look at the article in Sky and Telescope, August 1960, page 87.
