Jupiter rotation

The rotation of jupiter in little over one hour is captured in these two images. Jupiter undergoes a complete rotation in just under 10 hours, so the motion is clearly noticable in only a short time.
Io is seen to the left moving closer to Jupiters disc, and it passed behind the giant planet only an hour after the image to the right was taken.
