My session this morning was just about a write-off due to terrible seeing conditions.
However,I submit the attached (very) low res RGB and CH4 for the record as the latest large flake is developing on the western/following edge of the GRS.
No IR was captured.
Delighted to see that this latest development has been captured by imagers in the eastern hemisphere,
some with exceptional images. My next imaging window is tonight after midnight,although cloud is forecast.

I wasn't expecting to image within the next week. However,
I found Jupiter shining through a very thin cloud layer,
so I hastily set up the C8 in a race against the clouds that were predicted to arrive at any moment.
This was the first light of my new ZWO RGB filters,which I find to be much better than the Orion filters I was previously using with the this telescope.
- Io and its shadow is transiting the North Equatorial Belt.
- White Oval Z is directly north of the Great Red Spot.
- The Equatorial Zone is still orange. The southern edge appears to be finally losing its white color.
- The South Equatorial Belt appears to be split by a white zone. The southern edge of the belt appears more gray than brown.
- The Great Red Spot is highly sheared on the western edge.
- Another cloud sheared off the GRS a few days earlier is to the east of the storm.

Hi all,here are three images of Jupiter from last night. Seeing not so
good but at least the clouds went away this time :-)
The IR-G-B image shows the current state of the GRS,a new large chunk
of red cloud is detaching at left while the last remnants of the
previous event can be seen flowing off to the right. Internally the GRS
seems to have some high cloud obscuring some of its features.
The methane CH4 image was taken in poor seeing but it does show similar
features - ie a large shedding event starting on the left and the
remnants of the previous event on the right,with a faint connection
back to the GRS itself.
The IR image is interesting,it was taken as the GRS was close to
setting and the sun angle appears to highlight the thin streamer of red
material from the previous event that wraps up and over the GRS and off
to the right.

Imaged Jupiter May 27th targeting the GRS when near the CM.
The 685nm-Pass IR and Ch4 data is good and well resolves the structure currently evolving around the GRS.
The R,G & B data is poor,progressively worst with shorter wavelength although the RGB does still resolve the new flake at the F side of the GRS centre.
All channels show the stream of material curling off of the top of the GRS toward the P limb.
