Strange aurora over Saturn's north pole

The Cassini spacecraft - while intrepidly carrying out its mission of pointing a camera at Saturn and its moons from as many angles as possible, like a college-aged drinking enthusiast hosing himself down with a can of Axe body spray before hitting the bars - has found what the Astronomy Picture of the Day blog calls "aurora unlike any other seen previously in our Solar System."
It's fascinating how in this image the aurora in question appears to form a dome over the already mysterious hexagonal cloud formation at Saturn's increasingly mysterious north pole. Insane speculation being par for the course in Ufology, I can't help but imagine all this hubub being caused by some powerful, alien technology beneath those clouds.
