Clyde Foster氏の画像はSPCの縁が黄色っぽく見えている。ここしばらくの報告画像を振り返ると、ヘレスポンタス（Hellestontus;325W〜345W,-30〜-60）の南部は、SPCの縁が黄色っぽく記録されている。ヘラス周辺が
ダスティーであることと大いに関係がある。B画像では、朝霧やサバエウス（Sinus Sabaeus;320W〜350W,-10）の北に白雲が記録さ
れている。Christopher Go氏の観測画像でもSPCは同様に記録されている。特にSPC周辺の様子は興味深い。Mark Lonsdale氏の画像は
低緯度地方がダスティーである様子をリムに記録している。この時期の大気の特徴である。
In the image of Mr. Clyde Foster, the edge of the SPC looks yellowish. Looking back at the reported images for a while, the edge of
SPC is recorded as yellowish in the southern part of Hellestontus (325W ~ 345W, -30 ~ -60). It has a lot to do with being Dusty around
Hellas. In image B, white clouds are recorded in the morning fog and north of Sinus Sabaeus (320W to 350W, -10). The SPC is recorded
similarly in the observation image of Mr. Christopher Go. The situation around the SPC is particularly interesting. Mr. Mark Lonsdale's
image records on the limb the low latitudes of Dusty. It is a characteristic of the atmosphere at this time.

A short session (regrettably) but with some good seeing.
The two "fingers",at upper left,that have been quite noticeable recently are well see in the IR and R.
I think the left hand one runs on the inside western edge of Hellas,but I am open to correction.
Subtle features can be made out across the Hellespontus,Pandora Fretum and Noachis regions.

Seeing was very poor today. I could only stack 40% of my frames to get a decent image.
Sinus Sabaeus is at the CM of this image. Sinus Meridiani is rising on the left while Syrtis Major is setting on the right.
Hellas is very bright! Note the albedo feature showing up inside Hellas in the IR image.
