I predict that early on Thursday evening (Feb 19 in North America) the shadow of Jupiter’s Galilean satellite #1 Io will annularly eclipse #3 Ganymede. This will be occurring in the midst of a period in which the tilt of the satellites’ orbital planes allow for mutual Galilean satellite events to be viewed from Earth.

I’ve created two preview graphics and a timetable that can be viewed at www.CurtRenz.com/jupiter.html

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

EDIT: My Galilean satellite timetable for tonight (Feb 19-20) has now been posted.

Going to be clear tonight. (Ignore the temperature prediction. I'm going to).

Okay, I lied. I really did mean to observe this, but I cannot bring myself to go outside.

I can't blame you, Paulie. I guess that also means you didn't spot the one-day-old Moon. As a consolation, there will be a similar event on Saturday evening when Europa's shadow annularly eclipses Io. Shortly before that, Europa will transit Io. I'll provide details tomorrow. And don't forget that a littler earlier that day, the Moon will occult Uranus.

Meanwhile, on Friday evening the Moon will form a tight grouping with Venus and Mars.

I missed it all. I was starting to bundle up to go out, and then I suddenly had no desire to freeze. Sometimes the cold doesn't bother me, or at least won't stop me from going out, but last night I lost all enthusiasm as I was getting ready to go out. I guess sometimes even astronomy loses out to Netflix and a blanket.
