Definitely a Hole

Sometimes it's obvious that it's a hole in the center.  Why and how are these formed?  TBD I hope.

This is from LRO dataset M1502023627LC:

Dark Spots in Lunar Craters

I see an unusual number of these: dark spots right in the center of craters.  This one is typical:

from LRO dataset M1502023137RC.

Pixels in this image are about 1 meter in size, which makes the crater wall about 30 meters in diameter, with the dark spot in the middle about 10 meters in diameter.

An unusually shaped large (about 8 meters across) rock, from LRO dataset M1502016457RC:

and in LRO dataset M1502021744LC, there's an oddly shaped outcropping of rock:

Solar Tangent Arc

Yesterday morning (12/13/25) here at my location in southeastern Arizona USA, I witnessed a very rare solar tangent arc.

Lunar Anomalies #11

Not really an 'anomaly', but an interesting hexagonal crater.  I've seen these before so it's no surprise, but I wonder if any human eyes have ever seen this particular one?  Regardless, it's pretty cool and very enigmatic.  Even the inside of the crater is strange looking.  This popped up as my #1 anomaly for this particular image section.  This is LRO dataset M1502014536LC.

Lunar Anomalies #10

A couple of strange-looking rock formations on LRO dataset M1502007653RC near the edge of a very large crater:
