Jupiter’s Galilean satellites #2 Europa and #3 Ganymede will soon conclude a series of four weekly dual shadow transit events. The final pair of shadow transits of this series will occur during the night of November 06/07. During these shadow transits, #1 Io will undergo both an occultation by Jupiter and an eclipse by Jupiter’s shadow. Prior to these events Europa and Ganymede will begin their own transits of Jupiter.

I’ve created three preview graphics for November 7 at 02:50 CDT (UT-5), one as viewed from above Jupiter’s north pole and a second as viewed from Earth. The third is an event timetable. They can be seen by clicking www.curtrenz.com/astronomical then going to the page for Superior Planets.

Descriptions and photos of these events would be welcome additions to this thread.

Everyone utilizing my timetable please note that daylight savings time will end while the events are occurring.

I had to work last night, so I can't provide the detailed observation as I did for last week's events, but I did catch Jupiter about 12:10 AM CDST. At our midnight break I remembered the transits, so I grabbed my scope for a quick look. With a 9mm eyepiece and 133x, Jupiter looked rather lonely, with Callisto far out of view, until I noticed Io near the limb, just off the edge of the Northern Equatorial Belt. Without knowing the timetable, my guess was that in 10-15 minutes Io would be occulted, but of course I couldn't stay out for it. Curt's predicted occultation time of 00:21:54 supports my observation. I managed one half-decent image that shows Io's position before the occultation.



That's it. Nothing else to report.
