Despite the  jet stream of 47 m/s,seeing and transparency conditions were fine.
There were some occasional wind gusts but C8 Evolution mount was able to keep Jupiter centered and steady in the ROI which allowed me to produce 10 RGB sequences.
The best five sequences out of 10 were de-rotated 14 minutes.

Trevor Barry
Imaged Jupiter July 13th in variable seeing. Have good coverage of the region between Oval BA and the GRS.
The 685nm IR is the best of the data.
I note a compact dark spot on the Southern edge of the NTB with a large elongated dark structure above it,these are between the F limb and CM.
The NEB is dominated by four very dark features along it’s Southern edge.
The intricate structure following the GRS is best resolved in the IR data as is the structure following Oval BA.
A formation of compact dark spots is resolved below Oval BA and all of these data resolve a diffuse oval very far South within the SPR,
this feature was also present in all of my July 8th data.

Clyde Foster
Jupiter 13 July. Thankfully another session where conditions were a bit better than they have been recently.
The Clyde's Spot remnant is still seen as a dark,albeit indistinct,feature,whilst STB-DS6 is now sp the GRS.
Oval A8 shows as very white. I noted the dark,obvious,oval feature sf the LRS-1 in the north.
Looking at Chris Go's image of 9 July,it appears that two oval structures may have combined into one.

Finnally I was lucky to see the GRS,it was rising. Note Clyde's spot close to the CM (whitened STB).
STB-DS6 on the south/southeast of the GRS,very dark. LRS-1 on the NNTB is very close to the CM,too.
NEB is dark here,note the dark festoon on EZ.
A7 (white oval on SSTB) is almost setting. A8 on the following side and easily seen also to the south/southeast of the GRS.
Another white oval was also possible to see,thanks to the seeing that improved during the night,
I mean the tine white spot on SSSTB (S3-AWO-2) already on the preceding side.
