While the August 7th Titan cloud monitoring images didn't seem to have clouds the CL 1 CB3 filter views do provide a good view of the Tui Reggio Xanadu region. This enigmatic area is bright in the infrared VIMS images and has been speculated to be several possibilities, including a region of cryolava flow and more recently an area of ejecta from a huge ancient impact in Xanadu the crater of which has been eroded and has relaxed but still forms a circular and slightly depressed region visible in the infrared. The image below identifies the main regions using the Celestia program, then shows a 2006 VIMS image of the area (from
