QUOTE (Greenish @ May 26 2012, 11:50 PM) I'd be interested if anyone can tell if it is prolate or oblate. Me too! |

I'm fairly sure it is prolate, elongated on one of its equatorial axes. But we will need more views to get a good shape model. Phil -------------------- ... because the Solar System ain't gonna map itself.

Is that Mimas?
Taken on 23rd May from around a million km from Saturn. If my surname began with Hoag- and ended with -land I would be beside myself.  Edit: it is Mimas - that's Herschel to the left.

A little play-around with the best Methone image - processed to within an inch of its life. Is that a tantalising hint of detail in the darker area, or am I enhancing artifacts?

There is real detail in the darker area, in the form of slightly darker smudges. Real because it shows up in all the images, not just one. I don't see any obvious topographic expression of it, but the sun is nearly overhead at that location.
