This is a glorious mosaic. It is like the classic 1940s Mt Wilson photograph of Imbrium on steroids. The sunrise across east-central Mare Imbrium is perfect for graphically depicting the concentric mare ridges that define the inner rings of the Imbrium Basin. The inner ring that edges the Spitzbergen Mountains is almost continuous, but there are a few odd bits (Pico and Pico Beta) that don't seem to fit the larger ring that passes through Ancient Newton, Piton and the Archimedes Mountains. Wouldn't it be lovely to have a similar high res, low Sun, high tonal quality mosaic of western Imbrium - and then we could talk about why the rings there are so much weaker - or even non-existent - compared to the East. Oh, did you notice that part of the image is familiar?
