Dark Halo Craters
« on: June 20, 2010, 03:41:06 pm »
I am currently putting something together about Dark Halo craters. In the meantime I would like any that you find, or possibilities, to be posted in this thread with any questions you may have.

I put together a brief Dark Halo reference resource here: http://forum.moonzoo.org/index.php?topic=224.msg4425#msg4425

Dark Halo craters or crash site?

I don't have the coords anymore (and I'm not sure where in the forums I put the original), but here's the only one I know falls under the category (and I know because you identified it for me).


This is a beautiful dark-haloed impact crater DJ_59. If you ever find the coordinates for it, I would greatly appreciate it if you would post them. Thanks.

Thanks.  Is this one, or is it a trick of the light?

Not much question about the ones inside this crater.  I still haven't learned much about these things, but I'm guessing the impact on the large crater these are inside made the distance to the surface shorter, then the mini-craters were the result of venting.  Is that close (if confusing)?

Hi DJ

The large crater at bottom left looks like a normal crater to me, no dark halo.

Then I'm officially lost.  I figured if it wasn't consistent with a shadow it must be dark volcanic matter.  Back to the drawing board.

Thanks for the look-see, Geoff.
