As Jupiter and Earth reached their closest approach for 2009 (also known as opposition when the Earth is between Jupiter and the Sun), Christopher Go captured a number of excellent views of Jupiter and its major satellites over the weekend with his telescope in the Philippines. Included in these images was an eclipse on Ganymede caused by the shadow of Io crossing the larger satellite's surface. This is the opposite of what I've been talking about for much of the summer, where the shadow of Ganymede crossed Io's surface.
The animated gif of the incredible imaging sequence is presented at right. Don't forget to check out the rest of Christopher Go's Jupiter images on his website.
