As if the bright F and C rings and Cassini Division weren't enough of a clue, this observation was taken at high phase over the "unlit" side of the rings. I put unlit in quotes as there is obviously some contribution from Saturn shine as well. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Image from [EDIT: UN]lit side of rings. Movement of a sheparding moon and ringlet chunks can be seen as multicolored splots in the lower right part of the image:

Does Aegaeon (btw, is it spelled that way or Aegeaon as in Looking Ahead?) really look like a stick or is that motion smear? http://saturn.jpl.nasa.gov/multimedia/imag...7/N00150218.jpg Sure looks like the former case based on all the raw images. Is this a high phase shot? -------------------- www.flickr.com/photos/ugordan

Here's an animation that runs through 17 of the 18 Aegaeon NAC shots (skipping the second one, in which I just couldn't find it). Flickering is caused by Cassini using different exposures & different filters. It's enlarged 2x.

I can't think of anything more elongated, but what if this is a saucer shape like Pan or Atlas, being viewed edge-on? Definitely interesting. Thanks for the animation, Emily. -------------------- -- Hungry4info (Sirius_Alpha)

No. It is elongated as it should be in the sub- to anti-Saturn points, but from this phase it is hard to call it "the most elongated object".

Tantalizing. I'd love to see a RGB color composite and compare it to other small rocks, I'd guess this one will turn out to be bluish as well. -------------------- www.flickr.com/photos/ugordan

Each is a composite of about 6 or 7 frames, omitting the invisible or saturated frames, enlarged to 400%. Phil -------------------- ... because the Solar System ain't gonna map itself.
