Tonight, I had a quick peek at Ganymede's shadow, which was near the edge of Jupiter's disc and close to Jupiter's Polar region. This was a nice example for me of the 3D reality of Jupiter's Moons.

The ability of the shadows of the outer Moons to be anywhere on Jupiter's disc surprises and delights me. Its a nice change from seeing the more frequent eclipses of the inner Moons with their shadows always being far closer to the Equator.
