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.
