A first opportunity for observation after several weeks of bad weather was
provided thanks to a high pressure region above the UK.We had several days
with low clouds and still no observation was possible until the clouds solved
today,Dec 22.
This is an Lr-RGB observation.Seeing was variable from fair good to very good.
Especially interesting is the obvious beautiful cyan color of the STeZ here.

High contrast red light R610nm images,showing
some small dark spots or condensations at the SEB-s.
The animation shows them moving with the rotation.

colors of southern hemisphere Saturn
The current colors of the southern hemisphere of Saturn according to ToUcam rawmode observations on Dec 22:
Note especially an interesting difference in color between the SEB-n,which looks more tan,and the SEB-s(up)which looks a bit blue/magenta.As earlier mentioned,the STeZ color and the STrZ color are very different.Of another note is the color difference within the EZ,in which the EZ-n looks more yellowish.I have noted this also in older images.

明日は休日なので期待し準備していたが、シーイングが悪く、雲も覆い始めてしまった。

像の揺れや，ボヤケはそれほどでもなかったが、縞模様は見にくかった。

コメント：どうしてこんなに天候が不順の状態なのでしょう。透明度がこの季節にしては悪い。
かといってシーイングは悪い。今年の天候は、晴れ間が少なく晴れの天気は続かない。
土星を見ていると、気流のためか土星が振動しているように見え、詳細が判らない。
土星も大きくなって、後１か月程で衝になるが、普通の冬まで回復して欲しいものです。
