Rare Triple Shadow Transit on Jupiter - Jan 23-24

A rare simultaneous transit across Jupiter by the shadows of three of its four great Galilean satellites will occur during the night of January 23-24. This can be seen through modest telescopes. The next triple shadow transit won’t happen until 2032.

Bright Jupiter currently rises during the early evening for all observers. The triple shadow transit will be best viewed from the Americas.

I’ve created two preview graphics. They can be downloaded at www.CurtRenz.com/jupiter

I’ll publish on my website a detailed timetable for the triple shadow transit by midday on January 23. In the meantime, tonight’s Galilean satellite timetable appears there.

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

Here are a couple of unusual events that I predict will occur during the triple shadow transit across Jupiter on the night of January 23-24.

23:49:42 CST (05:49:42 UT) – Callisto’s shadow eclipses 54% of Io, while both of their shadows fall on Jupiter and appear merged with each other.

00:21:00 CST (06:21:00 UT) – A fully lit Io appears totally immersed within the shadow of Callisto that falls on Jupiter. (Io will not be shadow eclipsed at that time.)

It's too late to edit my OP. Overnight my webhost moved my website to a new server. html must now be added to the link I provided: Jupiter

You're welcome, Astrotoy. I too started visiting the Adler in 1955. Joe Guzman is a friend of mine who regularly conducts star parties there. He hosts the Chicago Astronomer forum: Home | The Chicago Astronomer

Thanks for sharing your fine photos, TEG. Glad you got to see the event.
