I could see from the B conditions on screen that RGB imaging was not going to give any decent results,
so rather concentrated on running a few CH4’s to monitor the situation.

5月は18観測日のうち9夜は気流状態が悪く撮影不能でした。今年は異常です。
6月のスタートは何とか撮影できる程度の状態でした

I wasn't expecting to image tonight,but I went outdoors to see the sky clearing to the south.
The stars were twinkling and the sky could've clouded over at any time,so we skipped the C14
and pulled out the 90mm Mak for a quick setup. Sky conditions were very good!
I believe this is one of my best photos from this scope!
- The North Temperate Belt is thin. The southern edge is orange while the north is dark.
- The North Equatorial Belt appears to have a few new rifts.
- The Equatorial Zone,except for the southern edge,is still orange.
- The South Equatorial Belt appears to have a dark spot on its northern edge approaching the central meridian.
- The SEBs is dark compared to the rest of the belt.
- The South Polar Red Spot is past the CM.

After a surprisingly successful first set of captures with the 90mm Mak,
I decided to step up my game and inserted a 2x barlow into the imaging train.
Previous attempts had failed because of poor tripod stability,
but this time with the barlow was much more successful.
- Oval BA is rising with a stream of dark clouds to its north.

fter a successful set of images with the 90mm Mak and no signs of clouds,
we decided to take out the C14 while there was time.
Turns out that was a really good decision since this is our best RGB image the apparition so far.
However,it did end up being disturbed by a thin layer of clouds.
- The North North Temperate Belt is showing hints of orange within its otherwise brown clouds.
- The North Temperate Belt is thin. The southern edge is faintly orange while the north is a thin dark line.
- There is a white oval on the NEBn at the central meridian.
- The North Equatorial Belt has a new rift past the CM.
- The Equatorial Zone contains an intense festoon approaching the CM.
- The EZ,except for the southern edge,is still orange. However,there is a subtle orange smudge at the CM on the EZs.
- The South Equatorial Belt has a teal spot with a detached tail on its northern edge. I don't recall seeing anything with this color on Jupiter before.
- There is a bright spot just off the SEBs on the CM.
- White Oval BA is rising with the STB Ghost trailing it.
- There is a subtle blue feature to the west of Oval BA. Is this an STB structured segment?
- The South Polar Red Spot is setting.

Since I needed to offload the previous RGB,a process which involves freeing a USB port for an external drive,
I decided to capture some infrared data while I had the USB hub for the focuser and filter wheel disconnected.
- The North Temperate Belt is nothing more than a faint line.
- Even though the EZ has traded its typical white color for orange in RGB images,it still looks normal in infrared.
- The teal spot on the SEBn in the RGB image is very dark in infrared.
- There is a subtly dark feature setting on the South Temperate Belt. Is this a new STB structured segment?

It has been a very long time since I've attempted methane band imaging.
The good conditions made it seem appropriate to start capturing them again.
After this image,a solid deck of clouds came in while working on an RGB set and ended the imaging session.
- The southern Equatorial Zone is darker than the rest of the zone.
- The teal spot that caught my attention in the RGB image is dark.
- The bright spot in the RGB image off the southern South Equatorial Belt is invisible.
- Oval BA is bright.
