RGB composite of May 3, 2011 WAC images. Tweaked to get more sharpness (see flickr page for processing details).

Surprise! An image of the southern hemisphere of Saturn reveals a South Temperate Zone storm! Methanovision [MT3,MT2,CB2] composite:
As far as I am aware, this southern disturbance was first spotted on May 10, 2011 by Efrain Morales (Puerto Rico) using an earth-based telescope: http://www.jaicoa-observatory.com/Sat_10_0..._0208ut-EMo.jpg -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

RGB composite of May 12, 2011 southern hemisphere image using RED, GRN and VIO images with some serious channel mixing done. The oval storm is dark in visible wavelengths, with a brighter surrounding ring of clouds.

Enhanced constrast of the CB2 image ("Wart-o-Vision") shows all the little bumps an knots in the Southern hemisphere in the overlay (and deliberate non-blend) of two frames taken several hours apart (a smaller storm can be seen to the E):
Animated blink of the two frames shows cloud motions and what looks to be a clockwise (cyclonic in S hemisphere) motion of storm oval: [Animated GIF: click to animate] Processing details on flickr. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Lovely. Looks like a painting.

Thanks! When I was looking at the raws I immediately thought of American artist Georgia O'Keeffe.

Low phase view of Saturn, in RGB and Methanovision infrared composite on May 15, 2011. The storm center is the smudge in the upper right near the terminator.

I also put together a CB.G.B composite of the 5/15 data. What is extremely interesting with these images is that while the spacecraft’s geometry is poor to look for spokes, note the crepe ring shadow has a distinct thinning about 1/3 of the way towards the left from the center of the globe. This is real and rotated with the rings between each exposure. Very distinct evidence of "spokes" actually thinning the region, I'd venture to guess.
The exposures were captured through the CB2, G, and B filters. Cloud features were warped slightly to compensate for the planet’s rotation between exposures. |

Two frame blink animation of May 15 and May 16 images coordinated on key features in the tubulent wake region. The storm is moving W relative to the wake turbulence. Parts of the wake can be seen to rotate counterclockwise.

How would I find out the exact times certain images were recorded? For example, images W00067528.jpg and W00067533.jpg appear to have been recorded one Saturnian day apart. I'd like to measure the movement of features between the two images, so exact image times become important.
