Still On the Limb
image by Jocelyn Serot, France
Yesterday we learned the names of all these features so now we are ready to talk about them. In the foreground is the bent Rheita Valley, a secondary crater chain from the Nectaris basin, and at top-left is a fault-like straight feature, also radial to Nectaris. The very odd bulbous slot of Rheita E is not radial to any basin but it seems that it ought to be a short line of basin secondaries. A number of small craters have brightly lit rims that are beacons of their freshness. Two small bright craters, the Headlights, on either side of Stevinus are the brightest features in this quadrant of the Moon when it is full. Another small bright crater at upper right near the dark floored Harlan appears to have somewhat faint rays, one of which extends between Harlan and Marinus - was this crater formed by oblique impact? And notice Adams B, the bright-rimmed, flat-floored crater just west of Adams. On Howard's image from yesterday you will notice that it has a very strange ray, so strange that it deserves its own LPOD.
