Have you ever observed Bailly? Its a big crater just on the western limb. It isn't very deep (maybe; there isn't a reliable modern measurement) for its original floor appears to be at least partially filled in, presumably with Orientale's ejecta. There is no evidence of a central peak, but it might not be unusual because at about 290 km diameter, Bailly is big enough to be a two-ring basin. Bill Hartmann and I thought it was 40 years ago, and Pavel's great image and the new overhead [[January_18,_2011|view]] provided by the LRO-WAC global [https://the-moon.us/wiki/Bailly mosaic] continues to provide hints of the putative inner ring. The mosaic image shows very well an Orientale crater chain crossing the far floor of Bailly, and a ridge associated with the chain is nicely visible in Pavel's image, as is a linear crater chain on the crater rim. While the terminator is near the western limb take a look for an inner ring. <br /><br />
