ヘラス(Hellas;275~315W,-30~60)付近に見えていたダストベールは、東にも広がり、アウソニア(Ausonia;W235~270,-55~-20)南部にも
広がっている様子が記録されている。プロメテイ（Promethei Sinus;W260,65）付近のSPCに見えていたダストストームは淡くなって
きており、ヘラス(Hellas;275~315W,-30~60)とつながっているように見える。青画像では白雲が見えているため、極冠からのエッジダスト
ストームの可能性がある。
Clyde Foster氏はエリシウム山（Elysium Mons;215W,+30）に白雲を記録している。ターミネータ近くになると白雲が発生するようだ。
The dust veil,which was visible near Hellas (275-315W,-30-60),spread to the east,and also spread to the southern part of Ausonia
(W235-270,-55--20). Have been. The dust storm that had been visible on the SPC near Promethei Sinus (W260,65) is fading,and
appears to be connected to Hellas (275-315W,-30-60). Since blue clouds show white clouds,there is a possibility of an edge dust storm
from the polar cap.Mr. Clyde Foster records a white cloud on Elysium Mons (215W,+30). It seems that white clouds are generated
near the terminator.

-------------------------------------------------------------------------------------
It was nice to be met by clear skies this morning after a lengthy period of cloudy weather.
Some reasonable seeing conditions came with it. A well-defined Syrtis Major is at centre right,
and it is interesting that Hellas appears to be almost clear of cloud and frost and is not clearly defined.
There is substantial cloud over Elysium,which is on the evening terminator at lower left.
I also think I may have captured the small North Polar Cap at bottom.
Unfortunately there is a severe edge artefact over the bright sunlit limb (can be processed out,
but felt that I should present the results "as-is").
