I haven't done a high quality stack and processing, but here's a preliminary image.

It's so bright that autostretch contrast makes the rest of Jupiter darker than normal.

Nice image Con. This thing is really long lasting. It must be that the forcing supporting this updraft is very persistent and related to the jet stream feature flowing around to the north of the GRS providing continual upward motion.

Today I revisited my Jupiter photographs taken in September. This photo, taken on September 5 at 11:25 pm (GMT + 10), also shows an upward jet near GRS and in addition to it in the Equatorial Zone I found a small flash similar to the one that Yu Gu captured near GRS on October 2. Near this flash is an area that resembles a Hot Spot that was hit by Galileo's probe.

Do you think it might be related to the updraft? The image does not seem to be an defect, but the spot is not so bright so near GRS on other photos.

Tonight's seeing was about the worst I have seen for a long time...

By the way, here's the fully processed image from 2020-10-05 with the contrast left intact to show how bright the breakout is. I actually see two white breakouts much more clearly now.

Had another extraordinarily good day of seeing 2021-10-07, and in my preliminary quick processing before going to bed, the bright spots are all but gone. The swirls are still there, but no bright white. The sharp angle around the Great Red Spot seems to have gotten quite round again.

Another very nice image. Yes, they have weakened. I think there is still one located 10 o’clock of the GRS accompanied by a dark blue area to its south.

I was extremely lucky as seeing was nothing short of exceptional last night, that's why I was so excited to post it anyway. When it's that good, the data does the work instead of us lol.gif

So I finally assembled the images into an animation: https://yugu.site/wp...?bwg=1633873943

Now I noticed something else that's interesting. There seems to be some very large scale dark features in/near the north polar region. They look like darker shades that are rotating with Jupiter. Anyone knows what are the reasons for those?

Yes, there does seem to be a subtle dark feature moving with the rotation. The question is, is it real? If it is real, we should see this effect in other animations.

Here are a couple from September 3rd (Tak FS-102), 5th (Tak FS-102) and the 17th (Mewlon 180c) that looks like they may have caught some bright spots near the GRS.  The one from the 3rd (last image) I think shows it best out of the three. I thought I had some better examples, but this is all that I can locate at the moment.

Leo has just posted a recent Jupiter image that shows two new cold/white convective tops with dark area in the following thread:
