Interesting stuff. However, my first thought was "which moon is this aurora associated with?" On Jupiter, there are bright spots associated with Io and Ganymede where fieldlines connected to the associated satellites intersect with the Jovian atmosphere. Is it possible that we are seeing the same on Saturn? The fact that it isn't even brought up maybe because these Saturnian spots don't share similar characteristics beyond being bright emissions separate from the main oval. Not sure.
