The bright spot seems to be less prominent when on the morning terminator than on the evening. One possibility is that much of the bright material is on a west-facing slope.

The bright spot seems to be less prominent when on the morning terminator than on the evening. One possibility is that much of the bright material is on a west-facing slope. If this were a geologically recent active region, wouldn't a reasonable expectation be that the crater floor is smooth as the material flows or falls onto the floor? It's hard to tell whether the crater floor in the zoomed-in version is itself cratered or those are image processing artifacts. My money is still on a shallow angle impact causing the center bright spot with a secondary impact causing the second spot. It also explains the variability in brightness between different viewing angles. Andy |
