解説（安達）/ Comment by Makoto Adachi
　Clyde Foster氏の画像では沈みかけのOlympus Monsに顕著な白雲が見られる。同じ画像にElysium Monsにも雲が写っているが、
Olympus Monsのような白さではなく、黄色っぽく見えている。南極部にはSP hoodが見えている。南緯60度付近のリムに明るい
部分が見えているが、これはEridaniaだ。Damian Peach氏の画像ではHellasの白雲が見事にとらえられている。Hellasから東の方に
雲が流れ出ている様子も記録されている。
In the image of Mr. Clyde Foster, remarkable clouds are seen in the sinking Olympus Mons. Elysium Mons also has clouds
in the same image, but it looks yellow rather than whiteness like Olympus Mons. SP hood is visible in the Antarctic. The bright part of
the limb near 60 degrees south is visible, but this is Eridania. In the image of Mr. Damian Peach, Hellas' white clouds are captured 
spectacularly. The appearance of clouds flowing out from Hellas to the east is also recorded.

Mars this morning. Cloud is evident over Elysium and also Olympus Mons,
which is on the evening terminator.
The subtle albedo features around Elysium(Propontis,Phlegra,
Trivium Charontis and Cerberus) are noticeable.
I suspect that the crater Milankovic may just be detectable in the R image,
although not confirmed.
Cloud is visible on the southern limb.
I am not sure if this is cloud that has been blown from the Hellas Basin,
or whether this is an indication of the formation of the South Polar Hood.
Any comments welcome.

気流が悪く、よく分からないが、肉眼でわかるほどの目立つ白雲は見られない。

Poor conditions so only one image obtained for the record. Hellas brilliant at bottom.
