Who needs one eclipse when you can have three

This is a neat image from Hubble - a triple eclipse. The moons Io, Ganymede, and Callisto were all casting shadows on the surface of Jupiter at the same time.

By the way, Jupiter is now visible in the morning sky. With a telescope or even a good set of binoculars, you make out one or more of the four Galilean moons (Io, Europa, Ganymede and Callisto) as tiny specks near the bright disk of the planet.
