Eye of the storm at Saturn's north pole

[stargazer3]

Hi! I'm really excited about recent APoD picture, which shows Cassini's photo of a gigantic storm on Saturn's north pole. They also have an animation! I can't wait for a colour picture and videos.

Meanwhile, since I still didn't state the purpose of this thread, what are the inner vortex dimensions? NASA's webpage says the probe took the picture from four hundred thousand kilometers away, but I can't find anything about the storm size.

Also, the http://saturn.jpl.nasa.gov/photos/imagedetails/index.cfm?imageId=4679 image shows an evident hexogonal structure, what on Earth is it caused by?

I do not think it is caused by anything on earth.
Sorry, could not resist ;).

I found 25000km as diameter for the hexagonal structure. Comparing this with an image of both together, this would indicate ~2000km for the diameter of the inner part.
