Jet stream was a bit weaker but seeing and transparency were something worse than yesterday.
Some high clouds were visible coming fast from southwest but did not reach my local meridian by the time I finished 10 RGB sequences.
Temperature 20 degrees Celsius,high temperature for a winter night,and zero wind.
Very peaceful night. Only 3 out of 10 sequences were a go to the de-rotation process.

Today is Jupiter's opposition day!
Fortunately,I was able to take some images of Jupiter although the sky conditions here was very frustrating.
First off,half the sky was clear while the other half had intermittent clouds.
Jupiter just happened to be on the cloudy side. Seeing and transparency was variable and I had to image between clouds.
The NEB shows the chaotic upheaval!
Complex rifts and outbreaks can be see with the dark material on the NEB.
The SEBn shows the turbulence from the GRS. The GRS can be seen rising on the second image.

A short session of reasonable seeing on Jupiter opposition day.
The GRS is setting at lower right,with Oval BA closely following it.
The complex structure immediately nf Oval BA can be seen. N4-AWO and WS-4 can be seen in the north,whilst S4-LRS-1 can be seen in the south.
There was severe Jetstream conditions,so I’m not going to complain about the results.

After only 6 minutes I began shooting to His Majesty,a bed of clouds covered the entire south horizon for more than an hour.
This is a 4 stacks derotation. NEB is showing intricate swirls of gas motions.
Two huge blue festoons,one towards the preceding limb and one in CM are projected to EZ.
Three little WOS in the NTZ and many dark patches over the NPR.
The NTB shows a train of dark patches and the NNTB has many dark spots.
The SEB-N appears more dense in the following limb and fades as soon as CM towards preceeding limb. The STrZ has a big spot just near the following limb.
The entire southern regions has many dense regions and the STB shows two little WOS.
Note: perhaps my best seeing since I started again to take planetary pictures.

The night of jovian opposition had capricious seeing,I tried to counteract using long wavelenghts filters

Imaged Jupiter July 14th at opposition,have only Ch4 and 685nm IR data before conditions deteriorated making any meaningful R,G & B data impossible.
That said,the IR data does have remarkably good depth of resolved detail.
There is a very small bright oval well resolved to the F side of the CM on the edge of the NPR.
A prominent formation of compact dark spots are lined up on the Southern edge of the NTB between the CM and P limb.
Considerable fine structure is resolved in the NEB with two prominent dark features along the Southern edge of the NEB extending into the EZ.
Interesting structure is resolved along the Northern edge of the SEB.
Two prominent bright ovals are resolved in the SSTB and there is a conspicuous,thin and quite elongated dash between the CM and P limb down on the edge of the SPR.
