Jupiter photographed from my backyard in Los Angeles, CA on September 7, 2023 (12 hours UT).  Jupiter's Great Red Spot is seen near the meridian and Galilean moon Ganymede -- the largest moon in our solar system -- is at the top of the photo near Jupiter's south pole.  The photo was flipped so North is down and South up. 

Here is a YouTube video about water-rich Ganymede:
