Giant Cave or Optical Anomaly
« on: August 16, 2012, 01:16:24 am »
Hi all.
I wander in here occasionally to see what's new.
I have also recently - for my own personal project - been scanning some of the regions of the Moon using the 'Target-LROC' site.
I found the attached 'object' or, rather, void on the northern wall of the Moretus C crater.
Is that a cave?
Any ideas anyone?
Also seems weird that there's detail all around the area except for the dark void that's been pixelated.
Either way, if it is a cave, it's a mighty big one!

Nice find kbdozz and welcome to Moon Zoo!

I'm looking for some NAC strips that cover that area and will post any showing your 'anomaly'.

It would help if you could provide latitude/longitude details for the object if possible.

I think in the first image it's nothing more shocking than the sun angle.

I also think it's a shadow. Moretus C is near the south pole ( Lat 72.6° S   Lon 11.2° W) so shadows will be a feature.

Nice to see you here kbdozz! :)

I've attached the ACT-REACT Quick Map south pole view. The northern walls are heavily shadowed.

I'm still putting cookies on it being a shaded overhang.

You're very probably right KM!

Two shots of same place from different angles would allow us to build an anaglyph which would definitely solve the issue.

That would most definatley help, but i suppose we'd have to wait for the next dataset release. And i think those happen every 6 - 9 months?

Thanks for all the responses.
I figured it was some sort of artefact from optics (or similar); still the moon is full of surprises . . .

Sorry for the delayed response!
Looks to be ~72.4S 11.8W on the Target MAP.
