What's going on here? The limb of Enceladus looks like it's all melted like wax! smile.gif

I'm going to hazard a guess at some kind of really strange image saturation from an over-bright Saturn maybe? If so, I've not seen that look so 'curvy' before.

The next image in the sequence is also strange: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=216997

Yep, those are the WAC equivalent of dust donuts. We can remove those via flatfielding when we calibrate this data.
