Very nice! 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.

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:

I think that is still the unlit side I do believe...

nice The moving parts really jump out in such a composite.

What the.... ? 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? -------------------- |

No it's Aegaeon, I just spelled it wrong... Noticed that last night...
The phase angle is around 75 deg. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

At 75 degrees phase angle, did we just discover the most elongated object ever imaged so far?

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.

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". -------------------- &@^^!% Jim!

Atlas is definitely thin, but this one appears to outdo it, assuming we didn't by chance get aligned at Aegaeon's equator. 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.

Best I can do with Aegaeon - images from the start and end of the sequence. Each is a composite of about 6 or 7 frames, omitting the invisible or saturated frames, enlarged to 400%.
