Astro0 (a contributor to unmannedspaceflight.com) had been looking through a 159 frame set of images that showed a tiny portion of Saturn's sunlit limb. He animated it just to see the effect and happened upon a pretty nice animation of a Saturnian aurora (click here for the animation). Which is likely the first time we are seeing an aurora on another world so clearly animated.
To be clear… the spots that stand still in the animation are artifacts of the images. The streaks are stars seemingly flying by due to Cassini’s cameras being trained on one spot as it and Saturn itself are moving through space. Astro0’s blog can be found here and I suspect will soon feature a post with more details on the animation in the very near future.
