View Full Version : Galilean Satellite Events - October 16/17

2010-Oct-10, 11:48 PM
Jupiterís Galilean satellites #2 Europa and #3 Ganymede will soon initiate a series of four weekly dual shadow transit events. The first on October 16/17 will be a limiting example. While Europa is actually transiting Jupiter, Europaís shadow will begin a transit as Ganymedeís shadow is exiting on the other side of Jupiter. During these events, #1 Io will undergo both an occultation by Jupiter and an eclipse by Jupiterís shadow.

Iíve created three preview graphics for October 16/17, one as viewed from above Jupiterís north pole and a second as viewed from Earth. The third is an event timetable. They can be seen by clicking http://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.
