夕方西空の金星が見やすい高さになり、観測所屋根からも暫く、見えています。
スライデイングルーフ開閉を当初の所まで開けるように改善し,C14でも金星が撮れるようになりました。
金星の南北領域の模様はUV,IRでは反転しています。からー画像でも模様が見えています。模様パターンはIRと同じですね！

I finally managed to process a selected batch of Venus images from April 14,when the CD was visible (in IR,near the terminator; arrowed on two IR images). Complex UV markings were also seen at the time,namely two linear dark features. IR and UV markings rotated with the atmosphere (see IR and UV gifs). By superimposing IR and UV images with close imaging times,it was verified that the CD was highly coincident with one of the UV dark linear features (the one closer to the terminator; see arrows on the third gif,IR-UV). Another episode of CD expansion to higher cloud levels??
