I predict that Jupiter’s Galilean satellite Europa will appear in annular transit across Ganymede during the evening of 2009 NOV 16. At the same time Callisto will be in transit across Jupiter. 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.
