I predict that Jupiter’s Galilean satellite Europa will appear in annular transit across Io during the evening of 2009 NOV 12. 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.
Europa Annularly Transits Io
2009 NOV 12 CST (UT-6)
20:03:41 CST Partial Transit Begins
20:05:29 CST Annular Transit Begins
20:05:36 CST Minimum Separation between Satellite Centers
20:05:44 CST Annular Transit Ends
20:07:33 CST Partial Transit Ends
Photos, descriptions and timings of this event would be welcome additions to this thread.

During the following afternoon/evening Ganymede will totally occult Io. This will be an evening event only on the eastern portion of North America, with afternoon occurrence elsewhere on the continent. At the same time, Io’s shadow will be transiting Jupiter.
For those who might be wondering about the differing terminology, an occultation occurs when a celestial body covers another one with an apparent smaller angular diameter; the converse is a transit.
