I predict that Jupiter’s Galilean satellite Europa will appear in annular transit across Ganymede during the evening of 2009 NOV 23. This event will be visible from western North America, but not in the east where Jupiter will already have set. I’ve created two diagrams. The first is a view from above Jupiter’s north pole, and the second is a view from Earth. They can be seen by clicking: http://www.curtrenz.com/astronomical . Below is my timetable.
