Seeing conditions were variable as the GRS transited and unfortunately the best RGB data was late in the session.
But good enough to identify the SEBs ring that has been moving around the upper edge of the GRS hollow and is now nf the GRS,and quite extended.
It appears to be pulling off reddish GRS material which was seen as methane bright in my earlier post,
reminiscent of the flaking events of last year,and hopefully fellow imagers will be able to follow events over the coming days.
The outbreak in the GRS wake is bright in all wavelengths.
Just np the shadow of Ganymede,I note quite a large number of small spots.
An early start (the 22nd for me,local time) allowed me another look at the GRS,2 rotations after my morning image set.
The flake is well seen in the CH4,as well as the bright outbreak in the wake.
It’s interesting that the SEBs ring which was extended along the nf edge of the hollow in the previous images
appears to have been reconstituted into a condensed circular storm,adjacent to the flake.
The flake is quite fine,and I personally am not convinced that we will get anything too dramatic happening,
but that wont stop me trying to follow events as best I can!
Either way,it is an excellent opportunity to compare the dynamics of what is happening with the events of last year.

This IR data was acquired near to sunrise,and the seeing conditions were deteriorating quickly.
Four image stacks were derotated to create this image.

The seeing did not help much. Jet stream intensified as a cold front got closer to my observing site.
I persisted and got better images later,with the GRS already setting and Oval BA present,
the best I could get this night. Note also Ganymede's shadow.
What mainly call my attention was the bright outbreak on the northwest of GRS,
I could see it shining during the capture sometimes. NEB is full of activity,s
pecially to the north of GRS. Dark spot on whitened STB also present. A8 is seen on SSTB.
