Description

Currently sitting out a long cloudy/rainy stretch and anticipating 2022's planetary season later this year, so I went back through some of last year's imaging data.  I found this short animation from last August showing about 50 minutes elapsed time.  The three inner Galilean moons were all close to Jupiter so I was able to include all three showing their motion as Jupiter rotated.  I had produced the animation last August but we were busy at the time getting ready for our move to Hilo, HI so it has been sitting on an external disk all this time.

Io and Ganymede had just emerged from behind Jupiter (on the left of Jupiter) at almost the same time that Europa emerged from a transit across Jupiter on the opposite side.  I had another camera on the C8 at the time so by the time that I switched to the ASI224MC, focused, etc, the moons had moved further from the planet.  But I was able to capture not only the rotation of the GRS but also the motion of the three moons as they moved away from Jupiter along their respective orbits.

Seeing was fairly good that night and I was able to capture albedo features on Ganymede, which was a first for my imaging.
