解説(安達)/ Comment by Makoto Adachi
 Arsia Silva Monsのすぐ東のダストストームはほとんど見えなくらいに衰えた。佐藤氏をはじめ、多くの画像では、Mare Acidariumの
暗さはない。Robert Heffner氏はMare Acidariumの北側に北極から三角形の暗部を記録している。これは、現在南極冠で頻繁に見られて
 Sonka Adrian Bruno氏はMare Sirenumの東隣にあるIcariaに明るいダストストームを記録している。北Electrisにも明るい

The bright part of SPC moved to the south of Argyre. The bright part out south of Aonius also shifts west to the south of Electris. 
The central portion of the polar cap is seen to be quite dark. .
The dust storm just east of Arsia Silva Mons almost disappeared. In Mr. Sato and many other images, the north side of Mare Acidarium is 
recorded in black. The dust storm near here is getting dim. However, compared with dark fringe, it is not as dark as the image because 
it is faint. Mr. Robert Heffner records a triangular dark part from the North Pole on the north side of Mare Acidarium. This is a phenomenon
very similar to the cold air balloon that is currently seen frequently in the NPC. There is no polar cap in the Arctic, but the cold air of the polar 
may have blew out. Mr. Horiuchi's image shows the situation in detail.
Mr. Sonka Adrian Bruno has a bright dust storm in Icaria east of Mare Sirenum. There is also a bright dust storm in the North Electris, 
but these are also considered to be dust storms due to cold.

Hi all,some slightly better seeing this morning on Mars with the IR750 longpass filter showing more detail than before. Maybe some of the obscuration is clearing away?
Valles Marineris is prominent at centre with the South Pole at bottom showing some isolated brighter regions. The three Tharsis volcanoes are faintly visible rising at left.

Time for another video showing how Mars looks now compared to a dust-free view:

This was a frustrating session as every time the seeing turned towards excellent strong gust of winds and passing clouds would roll in.
Had to use higher gain setting than I like to usually use. This side of Mars still looks very dust ridden overall.

This one also shot with very high gain setting.

The storms are clearly subsiding in IR,even if opacity is still strong in RGB.

Sinus Sabaeusが見えているが、Meridianiははっきりしない。ダストストームに覆われているようだ。
