 This last image on the night of the 19th
            contains the large 93 mile diameter walled plain Ptolemaeus on
            the left center, and Mare Nubium on the right. Several features
            in this area caught my eye. First, just above center is a small
            crater chain inside the crater Davy. It is 30 miles long, with
            small 1 - 2 mile sized craterlets defining it. A fragmenting
            asteroid has been deemed the culprit here. Also, another crater
            chain is just touching the lower left edge of Ptolemaeus, that
            includes the small crater Muller. Elongate gouges across the
            plateaus in the center are related to the formation of the huge
            basin Mare Imbrium,
