Little Visible Things
image by " rel="nofollow Umair Asim, Lahore, Pakistan
While processing this image Umair noticed an S (sort of) white band on the right part of the image. He strongly enhanced the image so the white S band is more prominent. He also noticed a white square-ish patch at 4 o clock, right-centeron the edge of the S. I love it when imagers carefully look at their images at the science as well as the image processing. In this case, the large bright S is the boundary between the young blue/dark lavas around the edges of much of Serenitatis, and the older, yellow lavas in the middle of the basin's floor. The colors come from the " rel="nofollow Clementine color imaging. The square-ish bright patch is a " rel="nofollow cluster of secondary craters whose ejecta includes a bright nimbus that makes the patch visible even though the craters are too small to be resolved. I lightened the west side of Umair's image to bring out some other interesting geologic features. Near upper left is a narrow, curved bright line, which is the gentle rise of the edge of the Valentine Dome. Immediately below it are a few, broad swells, where magma lifted up the surface, but didn't break through. Near center-left of the image are two mare ridges, one long and one short, both extending north-south. The long one is the officially named von Cotta Ridge, and the other one has no designation, for it is " rel="nofollow hardly visible except in illuminations as low as this. At the south end of the short ridge is a recently seen volcanic vent, and the lone peak north of the long ridge is actually the rim of the crater Linné. And keep looking - this image includes some additional prizes.
