Clyde Foster
Frustrating cloudy conditions initially with very poor seeing as the clouds thinned.
The RGB is heavily derotated and I had to push the processing harder than normal.
The IR is interesting. I note the broad dark region of the hollow on the western edge of the GRS,
and am wondering how this ties in with the recent circular appearance of the GRS.
The broad dark region has numerous light spots in it.

I am circulating a CH4 from my session of about two hours ago.
I will process the rest of my data and send in due course,but I suspect that there is some irregularity in the NW(upper left) of the GRS.
Possibly another flake may be forming?
Definitely needs to be monitored.
Just an additional comment:The irregularity may just be due to the leading edge of the latest flake rotating,
but I think it is worth keeping an eye on it.

The best RGB and IR I could get out from last night,to go with the CH4 I have circulated previously.
Unfortunately I had frustrating soft seeing conditions which negatively affected the RGB in particular.
The remains of the large flake can just be made out extending as a thin streamer from the NE corner of the GRS to the STrZ “band”.
The outer dark ring of the GRS appears to be quite thick on the NW edge,with a hint of possible reddish extension.

Niall MacNeill
The seeing wasn’t as good as the previous night,but good enough to show the progression of the streamer emanating from the GRS.

Ioannis A. Bouhras
Altitude from Greece is ~29  so imaging Jupiter is a challenge. Average seeing conditions today,transparency was poor also.

I finally caught the GRS!  The past few days have been exciting with the GRS. 
It has been battered by an SEBn oval and seem to have shrunk in the process.
I had to image early with Jupiter only around 30 deg to get these images. The GRS is setting so I can only get a few details.
Seeing was okay but transparency was very poor when I took the first image! The images improve as Jupiter got higher. The GRS is more circular now. The reddish material with the oval is moving on the p side of the GRS.
Note that this material shows as a bright streak on the IR and CH4 images.
The wake of the GRS shows multiple outbreaks and these are prominent on the methane band images.
The NEB is dark and narrow. [Christopher Go : Cebu Philippines]

Anthony Wesley
Hi all,only one very brief window between the clouds last night - just
enough to grab an IR and accompanying green and blue to make this image.
Unfortunately the GRS was well past the centre by that time but this is
the best I could manage,and the only image at all from last night.

The red streamer of material is still visible to lower right,with a
long tenuous connection back to the GRS still faintly there. The top
left of the GRS is starting to look a bit distended as well.

This image of Jupiter was in good seeing for such
a low altitude of 34 degrees.

[Mike Hood : Kathleen Georgia,U.S.A.]

Andy Casely
A brief break in terrible seeing for a look at the GRS just as it rotates away.
The large streamer has detached on the p. side,and there may be the very beginnings of the next one on the n.f. side.

A couple short bursts of fair seeing intermixed with long periods of poor,resulted in these views compiled from 4 mins of data centered on 22:12 & 23:12UT.
Max altitude for these was 32 degrees. Hoping for better conditions soon.

This represents 9 x 90s captures de-rotated in WinJUPOS.
The position of Jupiter in the sky was highly unfavourable (low in the sky over high-rise buildings to the west of my location)
and seeing was poor as a result,but the current events with the GRS are so fascinating that I had to try!
The "blade" of orange material is still,amazingly,connected by a thin tendril to the (now broken/fragmented)
band of dark brown cloud returning along the STZ.
