Tethys??

The smaller one is Enceladus and the larger one is indeed Tethys

Yet another really nice "close encounter" sequence between two moons seen by Cassini:

I don't have the capability of creating an animated gif... but if anyone is up to it, it should be a good one.

I know from the raw image caption that one of the moons (the one in the foreground, it looks like to me) is Rhea. What's the other one? Dione?

-the other Doug

Yes. It's Dione.

That's really a big sequence. I found the time for the GIF, but used not all - only 24 frames: (550 KB) http://www.greuti.ch/cassini/eclipse_rhea-dione.gif

If you look closely, Rhea shows a little rotation. Sadly the distance is around 2,4 million kilometres.
