Jupiter put on quite a show last night, with transits galore on its cloud tops.
Not since Comet Shoemaker-Levy 9 hit Jupiter in 1994 have I witnessed such amazing and dramatic sights on Jupiter.
Last night, January 23, was the night of the triple shadow transits on Jupiter, with Io, Europa and Callisto all casting their shadows onto the Jovian cloud tops at one, but just for 24 minutes.
In addition, the disk of Callisto and Io were also superimposed on the disk, though only Callisto’s disk was obvious. With it, for a time I could see Jupiter dotted with 4 dark spots.
I make no claims that the video shows amazing detail. I shot it with the biggest telescope I have at my disposal here in New Mexico, a short-focus 92mm refractor. Such an event really needed a large reflector with lots of focal length to do it justice and magnify Jupiter enough to see the details well.
However, I shot the video clips to serve as my personal souvenir of the event. I hope the video and my commentary convey some of the excitement of the night, in seeing an event we will not see repeated until 2032.
