Conditions were terrible with relative humidity of 92% and temperature around 13 degrees Celsius.
I was able to capture some SERs for a few minutes before heavy dew jeopardized the instrument soaking corrector plate and everything else.
The image,the one I could barely save,is for the record only.

attached 2 images from last night,unfortunately I had to cut the session short because of the clouds,it also rained last night.
The GRS is raising,proceeded by the red material which had circulated around it in the last days.

Jupiter RGB and CH4 from yesterday evening. Below average seeing and Jetstream was present,
so heavy-handed processing was again required.
There does appear to be reddish material to the west of the hollow. With the poor seeing,
I concentrated on the CH4 data. The reddish material does appear to correspond with a faint CH4 linear feature in that region.
I think we need to give it a little more time,
but it appears that the latest SEBs ring has not initiated a major flake as yet(unless this reddish material would be considered as such?).

This night the seeing never rose above that of the June 6th conditions,possibly a little poorer -
but the use of heavy culling in the quality % of each stack-size selected...
& integrating 4 sets of these stacks in WinJUPOS allowed us to achieve a slightly better image on this 2nd night.
The rgb & individual channels have deliberately had a small amount of noise/grain left in them,as were the previous images for the 6th:
I prefer this approach as a balance that still allows good resolution in difficult conditions.
Despite the conditions some of the activity in the GRS is on display here - the darker (reddish-brown)
material preceding the GRS displaying those south-extending "whiskers" that I have seen in other images...
if I may coin another descriptive term on top of all the other enthusiastic ones being used for the current GRS phenomena! lol

Imaged Jupiter June 7th in good seeing over a 2 hr session.
This is the best Jupiter data I have captured for this apparition.
These data have Oval BA on the F limb at the start of the session.
Interesting features I note; A large ghost like oval with a small bright spot at it’s centre in the NNTZ,
a large elongated red feature in the NTZ both of these are best seen in the 13:03 UTC RGB.
All RGB data well resolves a line up of compact blue spots along the Southern edge of the SEB.
A red oval is also prominent down in the SPR in all data.
