Snapshot of a Titan-Tethys mutual event from July 14th. Highly contrast-enhanced view added to bring up some surface features on Tethys.

Nice Dione-Rhea mutual event with the rings:

I don't think that's Rhea there, it's too bright and the terrain looks like Tethys so I'm gonna go with... Tethys?
Here's a snapshot with Saturn in the frame and two other small rocks visible. Prometheus and Janus/Epimetheus in the distance? -------------------- |

The CICLOPS "Looking ahead" page mentions a Dione-Rhea mutual event, so it should be Rhea: "On July 18, ISS will image Dione as it passes in front of the southern half of Rhea. Dione will be 2.19 million kilometers away, while behind it Rhea will be 3.09 million kilometers from Cassini. During this transit, portions of Rhea's northern hemisphere will be obscured by Saturn's main rings." |

I stand corrected. The raw histogram stretch to overexposure in some red and green frames fooled me.

3-frame animation of the Serpent Storm taken in MethanoVision[MT3,MT2,CB2] of observations on July 13, 14, and 17. The Cassini scientists did an awesome job lining up the camera, I barely had to adjust the coordination to create the animation.
[Animated GIF: click to launch animation] You can see a little darker blue vortex that approaches from the W and gets swept up and over in the N "wall" cloud. Counter-clockwise rotation of the storm also seems apparent. Here are the still frames lined up: Full composite image for July 17, 2011: http://www.flickr.com/photos/31678681@N07/5960014772/ Full composite image for July 14, 2011: http://www.flickr.com/photos/31678681@N07/5960014418/ -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Nice!
It's like if one belt of Jupiter is placed on Saturn. -------------------- |

The raw image page tells us the moon is Dione.
The CICLOPS "Looking ahead" page mentions a Dione-Rhea mutual event, so it should be Rhea: "On July 18, ISS will image Dione as it passes in front of the southern half of Rhea. Dione will be 2.19 million kilometers away, while behind it Rhea will be 3.09 million kilometers from Cassini. During this transit, portions of Rhea's northern hemisphere will be obscured by Saturn's main rings." |
