Description

Imaging conditions were poor last night with low transparency, a strong jet stream, and quite a bit of wind. Nevertheless, I wanted to watch the double shadow transit from its moons Ganymede and Io. The conditions didn’t cooperate early enough in the session, but I managed the following image showing Jupiter with Ganymede’s shadow in transit with Ganymede and Io to its right.

Ganymede, which shows some surface features in this image, is slightly larger than our moon and is Jupiter’s largest moon. Io is furthest to the upper right. It gets its bright yellowish color from the sulfur spewing from its volcanoes — as it is the most volcanically active body in the solar system.
