The Great Red Spot (GRS) is undergoing a makeover:
And this is the NASA press release (although this is not new news):
I think this could be a worthwhile undertaking to observe the GRS this June/July/August with one of your larger telescopes (e.g. 8" SCT and above).***
***The question is not if you can see the GRS in your tiny 4" apo (or my tiny Vixen VMC 110L); the question is can you see the outflowing streamer gas? I think this calls for a larger telescope (jibe: your contrast myth in your 4" apo doesn't help in real live).
