A neat RGB set recently came down, similar to http://ciclops.org/view.php?id=1725 previously released. It features Tethys, Mimas lit by saturnshine and another small moon at the right edge of the image, suspended in the rings.



My money is on either Epimetheus or Janus.
At the time, distance from Saturn was 2.6 million km and phase angle was around 112 degrees.

I'm pretty sure it's Janus. In fact, one of the two "Kodak moments" planned for S19 is a March 13, 2006, image very similar to the thumbnail you posted.

Wow. Are you actually involved in the project or just know people who know people?

Janus it is, then! cool.gif

As I understand it, the other KODAKMMT planned for S19 is slated for April 2, 2006:

It is indeed Janus

Here's an (approximately) true color shot of Saturn taken on March 16 with the wide angle camera. I wish there were more of these lovely crescent, PR shots.



Note a small, dark speck just below the ringplane. According to Joe Knapp's excellent http://cassinicam.com/isslookup/, it's either Pan or Epimetheus.

Did someone noticed this family portrait? (Rings, Enceladus, Rhea and... Pandora?):

Edit: using raw image analysis tool, just verified is Pandora and... we should have also Atlas somewhere!

Ahh, its not Pandora, its Janus. And its Tethys not Rhea.

Without knowing which images this is all I can say is that its too big and too far out of the ring plane to be Pan so I'd go with Epimetheus.

A Crescent Saturn

Wed, 19 Apr 2006 - This view of Saturn shows a thick crescent of the planet bathed in sunlight with the rest in shadow. Three moons are visible in this photograph: Mimas, Ryea and Tethys. Cassini took this photograph on March 11, 2006 when it was approximately 2.8 million kilometers (1.8 million miles) from Saturn.
