Double shadow transit on Jupiter October 19th 2022

Explanation: A fairly rare double shadow transit event occurred on this night. Jupiter's largest moon Ganymede casting a large shadow on its cloudy surface, with some surface details visible on the moon itself. According to some scientists Ganymede is having a sub surface ocean beneath the icy layer.
Europa shining as a bright spot in front of the planet, casting it's tiny shadow at the edge of the Great Red Spot.

The Great Red Spot is visible and makes a good size comparison with Jupiter's two inner moons. Note how much larger Ganymede's shadow is than Europa's.
