I took a crack at the storm on my blog. http://planetimages.blogspot.com/2011/03/s...-on-saturn.html

Very subtle, Ted, I like that a lot.

Awesome. I get the sense that it is disrupting the belts to the North.

I think it is disrupting belts to the South. In Ted's processed image, I think the storm is located to the W of the little "bright V-shaped" indentation and the storm oval itself is not really obvious in visible wavelengths (but evident and bright in Cassini methane transmission images). The storm is slightly oval and oriented SW-NE (the bright V-shaped region is at the E edge). Immediately under this region, the clouds at the southern edge are getting churned up.
Since this image was taken, some of the bright clouds (both north and south of the storm oval zone) have kicked up and become more impressive. Check out some of the images from the 18th and 22nd of March in the IPOW database: http://www.pvol.ehu.es/pvol/index.jsp?action=iopw -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Saturn MethanoVision RGB[MT3,MT2,CB2] composite for March 21, 2011:
The storm oval can be clearly seen in this composite as a brighter gray upwellling with the bright white "pickelfork" cloud structure stretching to the E. Compare with Ian's image above. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Here is a downsampled comparison graphic of Cassini MethanoVision composite MT3,MT2,CB2] and IR-visible[CB2,GRN,BL1] raw image composites, and corresponding ground-based images of the north temperate storm over a three month period (January - February, and March).

Excellent Ted-
I downloaded and animated the best frames of the Hubble data too: Saturn storm animation Be sure to watch it in HD. |

Very nice! Good view of the ring spokes too- I'm not aware of the spokes having been seen from the Earth before, though maybe they have, and I've missed it.

Nice comparison Mike and my deep admiration of images from amateur astronomers!
And thanks to Ian, Ted and others for very good temporal coverage of evolution of the storm! -------------------- |

MethanoVision [MT3,MT2,CB2] of the big storm on Saturn on April 25, 2011. High Pass CB2 layer added to enhance detail. A small section of ring containing the moon (Rhea) was shifted to match the CB2 base image.
Compare with the RGB composite here. The storm center is evident in MT3 and MT2 images, but not the visible or CB2 images. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
