I feel like I vaguely knew that Jupiter had a short day-night cycle, but Jesus that thing spins so fast.

When you think about how big they red spot is, and how fast it is traveling around that huge planet...

Don’t forget that there’s also the spin from earth that basically goes the other way when staring at Jupiter so that probably contributes a little bit too.

I'm no scientist, but it's so far away and so large that I can't imagine that earth's rotation has any noticeable effect other than its position in the sky. Happy to be proven wrong though.

When I'm looking at jupiter with my telescope it's in view for about 30-45sec before I have to readjust it. I'm brand new to amature astronomy but I do know it moves fast even looking from here.

Sure, I agree that it moves in the sky, but not that earth's rotation would have any noticeable effect on how its rotation appears to us

I figured maybe just a slight effect. But you’re probably right.
