View Full Version : Dual Shadow Transit Across Jupiter - August 23

2018-Aug-23, 04:45 PM
The shadows of Jupiter’s Galilean satellites #1 Io and #2 Europa will appear in simultaneous transit across Jupiter during the evening of Thursday 2018 AUG 23 for North American observers.

I’ve created preview graphics that can be seen on my Jupiter webpage: https://www.CurtRenz.com/jupiter.html

Photos and descriptions of the event would be welcome additions to this thread.

The double transit is at exactly the time needed to mess with the heads of all the students in one of my nighttime lab classes, which first meets this evening. "How many big moons did you say it has?" I'll see whether anyone can actually spot the moons in transit (which is a very subtle thing most of the time).
