Seeing conditions remain decidedly uncooperative.
I am wary of reading too much into detail under these conditions,
but it is interesting that the plume from the chimney appears bright-ish in Methane as was also seen in recent images posted by Trevor Barry.
The Methane also shows a possible small bright spot sp the GRS,but again I would be wary and await better resolution images.
I had to push the processing harder than normal for both the IR and RGB.
A pre-midnight set from last night with the large outbreaks in the GRS wake,the Clyde's Spot region sp the GRS and the dark spot approaching sf the GRS.
Given the seeing,most data was rejected,so I'm not complaining with the results

Jupiter shot this morning,in average or (or probably somewhat less) seeing conditions.
"Clyde's spot" remnant and GRS are detectable.

Seeing today was poor-average at 5/10 on my estimation.
The jet stream was VERY strong,and there was a lot of humidity in the local atmosphere.
I had to boost the gain quite a lot as the imaging session elapse
Near the end of my observing session while I was capturing IR,the skies were very turbulent,humidity was high,and focus was difficult.
I also had to boost the gain a lot more than normal,which indicated a heavy loss in transparency.
After less than 20 hours since my last imaging session, the seeing conditions were slightly better.
I had to derotate 11 images to get a nice result in the end. Luckily, while the seeing was somewhat poor (6/10),
it was at least steady enough to have a few stacks that were usable.
