Christopher Go
It was very windy this morning.  Seeing was unstable because of the shaking but transparency was very good.

There is a feature on the NTrZ around the area of the CM.
This feature is bright in IR and a little bright in methane band.  The NEB and SEB looks quiet in this region.
There seems to be two cyclone features on the STB disrupting the band.
There is also a large oval on the south polar region .

気流は安定しない、雲に覆われて諦めた。

この経度では濃いSTBが目立つ。SEBは内部には細かい模様が見えるが穏やかです。
IR画像(685nm)カラーカメラとモノクロカメラでの比較。
感度的にはカラーカメラの方が高いが最終的にモノクロカメラの写りが良い(当然ですか!)。
ただカラーでもそれなりに写るので捨てがいたいやり方です。

After weeks of cloud and rain, I finally had some clear skies this morning.
The seeing started off being reasonable for the IR data, 
but continued to worsen as the morning dawn arrived with variable clouds.  
Had to wait for almost an hour for the clouds to part so I could capture a short sequence of colour data.
