enjoy!
Notice how in the images the white spot appears to go into darkness later than the rest of the crater. This suggests it is raised. Maybe a mountain?

I was thinking they looked like a hole the way they get smaller towards the limb. This gif by someone on UMSF shows it better perhaps:

Can't wait to see what they are though!
