The solar system is a happening place this week! I just learned of a major storm in Saturn's northern hemisphere, being monitored by the usual band of talented amateurs. See this site for a list of recent images. Chris Go's site has a particularly nice image.

So it would seem.

Question to anyone knowledgeable: Is the storm drifting within the larger atmosphere like the GRS, or is it fixed in longitude? Reason I ask is that it looks very much like a plume of sorts in this image, with the prevailing winds peeling off material from the top of the emission.

Would be interesting indeed if this is a manifestation of some sort of surface disturbance (whatever the word "surface" might mean on Saturn, if anything...)

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
