雨天直後の晴れ間で、透明度は良かったものの気流状態か芳しくなく、不明瞭な画像しか得られなかった。

Hi all,yesterday the fog cleared for a few hours,seeing was good,and
transparency was constant. Most of the time I invested in collecting data
for pending work on the vertical structure of the Jovian atmosphere (CH4
727,890 and 1000nm; continuum 750 and 950nm). At the end (before the fog
returned),I grabbed two additional images with filters that needed
testing. Specifically,a Baader 672nm/4nm (very narrow S-II filter,that
here behaves as a continuum filter,in the red wavelengths),and a
1010nm/38nm Pixelteq filter,that other observers (thank you!) recommended
as adequate to visualize the Venus night side,since it spans the 1.01nm
thermal window. In Jupiter,it behaves as "wide" 1000nm CH4-band filter. It
is as easy to use in Saturn as the CH4 727nm filter. I'm curious to
quantitatively compare results from this filter with those obtained with
the 1000nm CH4 filter I regularly use (1000nm/20nm,from IDAS).
These images were obtained with my 14" LX200 @ f/10,with a Player one
Mars-M II (IMX462M). Five 1min SERs were derotated in JUPOS.

寒気流入で北風も強くシーイングは最悪。
雲の流れの隙間を突いて5枚のみ撮影できましたが細部は分からず。

昨日より一段と寒くなり、冬支度での観測となりました。
シーイングのさらに悪くなり、大赤斑がボンヤリとしていました。

A fascinating massive blue feature has formed at the base of the NEB west of the GRS,
possibly secondary to the collision a few days ago.

Having had to prematurely end my Saturn session with strong gusting winds from the west,
I tried Jupiter to the east of the CM,and found some reasonable conditions.
Although the recently reported merging ovals in the south were detected,resolution was not good enough to add value.
The leading section of STB Segment G is showing some interesting activity.
The rather prominent hot spot on the NEBs was quite dramatic and appears to show a central dark spot.

Attached in an observation of Jupiter made on 18th November in moderate conditions. Some interesting features on the disk:
S3TB-SSTB: Region seems to show large gaps,two white ovals visible. Spot forming near the GRS?
STB: Visible on the prec. side of the disk and seems to curve up towards the SSTB.
SEB: Rather broad,SEB(s) rather dark. SEB(N) somewhat irregular in places and grey in colour.
GRS coming into view- seems to be harder to see it tonight.
EZ: Very active,a number of festoons present and there seems to be a yellowish EB present.
There was also a very dark bluish barge in the EZ/NEBs boarder.
Aside from the shadows of the satellites,this was one of the darkest features
I've ever observed on Jupiter with an intensity around 7.5- quite a remarkable object!
NEB: Very active- the region around the dark barge was particularly complex with small brilliant white regions
(plumes?) visible.
NTB: Visible as a faint bluish grey band.
NNTB: This appeared as a dark think band. The NNTZ was also fairly well defined.
By 2100UT the wind had really picked up and seeing had become poor. Closed down.
