Quick stitch of 21 images. There's a whole lot more images in this sequence if some brave soul wants to make it wink.gif

Wow... we've had MER Monopoly...

I think we just saw the first CASSINI Jigsaw... laugh.gif

Note to all: I had the idea first, and I'm in the middle of watching THE SOCIAL NETWORK, so no-one get any ideas about suing me in years to come, ok? tongue.gif

Just got back from London: drooled over Charlie Brown (not literally), gawped at Ralph's penetrometer -- and even touched a chunk of the Titanic's hull!

Oh, and here's a quick RGB composite from this latest, bountiful, batch of raws:

In terms of scale how does this storm compare to those that have previously appeared?

Nice work Mike! smile.gif

Here's a false-colour NAC view of the head of the storm (MT2/CB2/BL1):

Are the clouds in the storm moving fast enough to cause some motion blur in the images?

If you take a look at that image, the cloud features on the left have sharp boundaries, the clouds in the storm look very soft - like motion blur?

It sure *looks* like motion blur, but I don't think the numbers work out. The resolution of that image is about 20 km/pixel, and typical Cassini ISS exposure times for sunlit objects are maybe 1/100th to 1/10th of a second. So to get a couple of pixels of blur would require cloud speeds of 400 - 4000 kilometers/second- the clouds would exceed escape velocity.

CB2 frames are 3.2 seconds exposures. MT frames are longer IIRC.
