Tonight: Jupiter’s major four Galilean moons Io, Europa, Ganymede and Callisto are in 1-2-3-4 order, from 19:31 Universal Time (UT) when Io swaps places with Europa, until 21:16 UT, when Io disappears in Jove’s shadow.
This event favors Europe, Africa and most of Asia. Jupiter is headed towards opposition for 2023 on November 3rd, ruling the night from sunset ‘til sunrise. The waning gibbous Moon joins the view this weekend, passing 3.1 degrees north of Jupiter Sunday night.

Right now in the UK it is clear and blue sky, so the fact this event is happening is a clear guarantee it will be at least cloudy tonight.
If I get a chance to take a look, I will, see if my binoculars will allow me to see them.
