It was mostly overcast when I starting imaging. If it wasn't for the GRS,I would have gone to bed.
I had to use autohistogram feature of Firecapture because transparency was really crazy.
It would go for 1-3/5 in a second. The clouds cleared up later in my run but transparency was still very poor.
Seeing was excellent though.
The GRS is very well resolved. Note the flaking of the NW side of the GRS.
There is also a small dark spot of the W side of the GRS. The outbreak on the wake of the GRS is very active!
Something seems to be brewing inside Oval BA. The middle of Oval BA has become a little dark.
It is also dimmed a little in methane band. Note the area between the GRS and Oval BA looks very active in the Methane band image.
The south polar red spot can be seen below Oval BA. The NEB upheaval is still active.
And the NNTZ LRS can be seen setting on the upper right.

短時間でしたが晴れ間がありました。
右の周縁減光中に大赤斑がうっすらと見えていました。
ここはNEBに拡幅がまだ及んでいない区間です。
SEBZのwhite bargeの先端部や、A5後方のSSTB暗部などがよく見えました。

The best I could get from the soft seeing conditions last night.
Hopefully Juno may get a good look at the NEB activity as well as the f end of the STB Spectre.

Here is an image of Jupiter with GRS coming onto the disk. Reasonable seeing for 18 degrees.

Imaged Jupiter July 22nd fair to good seeing. I note a large red oval in the NNTB.
There is a tiny compact bright spot well seen in the NEB in IR R and RGB data midway between the F limb and CM.
The GRS chimney remains open and there is a elongated blue dash below and to it’s P side wihtin the NTZ.
Oval BA is just seen coming in from the F limb in IR,R & RGB,well seen in Ch4.
A small bright oval is resolved in all data near the CM in the STB.

The first two interesting things here are the two bright structures close to each other on NEB,new rifts just starting there in this image.
Besides it we can see NN-WS6 and NN-WS7 (preceding side),the area of the NTB rifts (Jet stream spot outbreak on NNTBs).
A5 on SSTB is still visible here. What is this kind of "indentation" on SEB on the preceding side,stlill close to the CM?

Here's an image from 22nd July as we continue to trial the ASI462MC camera for ZWO.
Still not finding really the good seeing conditions we would wish for,
although this night was looking good until unexpected issues caused us to lose possibly valuable data:
nonetheless it seems to add to our thoughts that the sensitivity & low noise aspects of the camera are very evident properties.
Of particular interest on Jove this night is the "snake-like" filament that connects the "wakes" of both the OvalBA & the GRS -
these 2 features becoming much closer together of late...& this connecting filament possibly an early indicator of upcoming interactions...? A later image still to process... ;)
