Jupiter is bright in the early evening sky right now. (Its the brightest thing in the night sky after the moon, you can’t miss it) With a small scope or binoculars you can see the 4 bright moons as well as banding on the planet. If you get the timing right you can see the great red spot as well. You will need to look up when to look for that, see the Sky & Telescope web site for times. Jupiter rotates about once every 10 hours, so it will change night to night, you can even see changes over a few hours if you look carefully. (Sketching helps here).
There are also times when you can see one or two of the moons moving across the face of the planet, that is very cool to see. Again Sky & Telescope will have times.
