NASA News: Amateur astronomers help NASA track storm on Saturn
'Amateur astronomers are helping NASA scientists on the Cassini mission track the most powerful storm yet observed on Saturn. The storm is in a similar location to the "Dragon" storm reported last year - -http://antwrp.gsfc.nasa.gov/apod/ap050225.html so it may be a reemergence of that storm or a new storm. According to the RPWS [Cassini's Radio and Plasma Wave Science] data, the new storm is generating lightning flashes several times more frequently than the original Dragon storm, and the lightning is as much as five times stronger. At approximately the size of the continental U.S., the storm dwarfs terrestrial thunderstorms. Apparently, it is much fiercer as well -- radio signals from its lightning are more than 1,000 times greater than similar radio static from terrestrial storms.'
