Description Since I had a a number of stacked frames, one stack from each of close to 40 videos, I decided to do an animation of the shadow of Io moving across the Jovian disk while Jupiter itself rotated. The image quality wasn't quite good enough to show where Io itself was clearly, so I did a little graphic embellishment to indicate where the moon was that was casting the shadow. It is interesting to note that Io's shadow overtakes features in the Jovian atmosphere due to the viewing alignment and speed of rotation (Jupiter) vs speed of revolution (Io).
