Some very nice seeing indeed on 17th October for the rather interesting area around the Great Red Spot.
Material from Clyde's Spot DS7 (rising) is interacting with the bottom of the GRS,
and is a chain of dark patches in methane.
There is a very interesting little bright spot on the STB just p. the GRS in the RGB image.
This is quite reminiscent of the appearance of both recent STB outbreaks,especially the precursor to the most recent one,
in almost exactly the same location w.r.t the GRS.
It may be very well be worth watching this spot for any outbreak/activity in coming days!
Nothing there in the methane band,despite excellent resolution. There's a complex outbreak on the GRS wake.
Here’s my full set from a cloud-interrupted session on 17th October,16-19h after PJ37.
Seeing at the start was superb,but not so good for the last set of images.
The GRS was prominent early,followed by Clyde’s Spot DS7 at the meridian for the second RGB,as Oval BA rises.
DS7 is a very big complex dark and light region now.
Material from DS7 is now interacting with the lower side of the GRS,and is generally dark in methane.
The very interesting bright spot just leading the GRS on the STB is quite visible approaching the limb,
in a similar manner to what we saw in the precursor for the most recent STB outbreak (Spot 8).
Watch that one for activity.
I’ve included the two images sent earlier as well.

Conditions were pretty hopeless last night with a cold front moving through combined with strong jetstream.
RGB was a write-off,and submitting the IR's and CH4 for the record only.
I do note the substantial SEBs ring about to enter the GRS hollow.

Here is an image from home on the 17th. Poor seeing low in the sky,though the GRS and NEBn barges are well seen.

I have been away for a few days and haven't had the chance to process these RGB & IR data from 17th October.
I made 3 extended runs,with the GRS in transit and rotating out of view as Io started its transit.
The seeing was fairly good throughout.
There appeared to be a couple of rings entering the RSH and the chimney was open at this time.
There is a remarkably dark spot at the southern extremity of the RSH.
I had good seeing for a long run on Jupiter back on 17th October.
I made 25 RGB runs. I have already published the integrated images.
This is the sort of thing you do during periods of extended cloud and rain as we are experiencing at the moment.
Producing an animation with a moon when imaging in monochrome RGB,is quite a challenge.
This animation is over a period of time from 09:44 to 11:19 UT
i.e. ~ 2.5 hours.
This aspect is particularly interesting,with the GRS fairly central at the start and rotating right to the limb by the end.
The fact you can see it almost edge on is a testament to the seeing throughout.
The Oval BA rotates into view as Io moves in,to then transit the planet
