What you see is the Aristarchus Plateau,
I thought that was roughly diamond shaped with Aristarchus at its (my image orientation) bottom right ... this is more or less but not completely enclosed by the circular structure I see, the bottom arm of which appears to be "ray like" in its brightness and to start off with coincides with the bottom of the diamond but extends further left, whilst the top arm (more of a contrast change than a structure) cuts off the top right corner of the diamond.

The actual diamond shape of the plateau is badly shown in my image above, due no doubt to the lighting. A crop of a similar area of my image of Nov 01 shows the Aristarchus Plateau beautifully but it's much harder to trace the circular structure I noted above. That's what I meant by "ever-changing but timeless" ...

2010 Nov 01, 0610 - 0617 UT. Same instrumental details as above.
