Lunar Anomalies #9

I'd sure like to better understand these dark circular areas (holes???) right in the center of craters.  I see these quite a bit.  Here's one of the latest from LRO dataset M1502002126LC:

Lunar Anomalies #8

When I look at a histogram of the data values, I get some very strange structures.  Here are two fairly typical examples:

This is just a normal histogram -- so the x-axis (range 0:255) is the data value and the y-axis (range 0:128) is the number of pixels that have that data value.  These are 64x64 subarrays, so there are a total of 4096 pixels represented in these histograms.

These are telling me that the distribution of data values has a varying structure.

Weird.

Here are the histograms of the top 225 of a section of LRO dataset M1502001921LC:

I know, hard to see any details.  The point is to show the distribution of histograms.

Not really sure what's going on here...

Lunar Anomalies #7

LRO M1502001180LC

Lunar Anomalies #6

Interesting shape of that object at 1 o'clock:

LRO data M1501994399RC

Lunar Anomalies #5

Again, not an anomaly per se, but still pretty cool looking.  According to a little bit of research (and thanks to Grok) they appear to be things called "Micro-Rilles" associated with volcanic activity (at least in theory):

Lunar Anomalies #4

This really isn't an anomaly -- it's just pretty cool looking:

This is in the LRO dataset M1502008085LC

Lunar Anomalies #3

This was discovered because it is the highest ranked 'not the moon' (64x64 pixel) image section in the input LRO image:

Lunar Anomalies #2

Top 225 sections that are 'not the moon'.  Highest is at top left, and then moves right and down.  This is from the LRO dataset M1502045101LC, and is my section 'c'.  These are 64 by 64 pixel sections, which work out to be about 50 meters by 50 meters.

The locations of the 225 top 'non-moon' areas are marked in red.

This is the sorted MSE plot:

Here's the same image, but my section 'd':
