解説（安達）/ Comment by Makoto Adachi
今日は、たくさんの観測報告を受けた。日本からはダストストーム付近が観測できたが、いずれも観測条件が悪かった。Niall MacNeill氏が、
このダストストームを鮮明に記録した。SPCのエッジからの吹き出し幅を鮮明に記録している。かなり大きな吹き出しになっている。
この吹き出しの北側にv字型の明るい部分ができているが、これはこの時期に見られるノーマルな姿である。Eric Sussenbach氏は、
この正反対の地域を観測しているが、こちらはノーマルな火星面をしていることが確認できた。
Today I received many observation reports. Although the vicinity of dust storm was observable from Japan, the observation conditions
were bad in each case. Mr. Niall MacNeill recorded the dust storm clearly. The width of the outflow from the edge of the SPC is
clearly recorded. It's a pretty big outflow. There is a bright v-shaped area on the north side of this balloon, which is the normal
appearance seen at this time. Mr. Eric Sussenbach is observing the opposite area, confirming that it has a normal Martian surface.

The dark side of Mars. Some subtle cloud appears to be hanging over the Northern regions of M Erythraeum and Margaritifer
Ophir/Candor has been quite bright recently.
I captured an extensive set of data(extending over a period of about 70 mins) following some overnight interaction with Niall McNeill
(thanks,Niall) regarding the edge artefact issues I have been experiencing.
I haven't fully optimised the results,but could see some improvement in the situation.

This capture shows the Hellas Basin more clearly than my image of 2 days ago.
It seems that there is a dust storm across it and probably impacting the southerly parts of Syrtis Major
and spreading to the Hesperia Planum and Mare Tyrrhenum. There also appears to be distinct bands of dust.
The bright spot on the p side of Syrtis Major is still there and there is also one to the north of the promontory.
The white bulge from the SPC remains. It could be lighter coloured dust clouds given its longevity,
which I believe makes the more transient water ice clouds a less likely possibility.
I made a second capture of Mars on March 20th,some 1.5 hours after the first.
The dust clouds are clearer and their structure more evident in this second image as the Hellas Basin has rotated to the central meridian.

シーイングは中程度だが、円盤像にしっかり見える。模様もほとんどのものが確認できるが、シャープには見えない。
最終の観測は、すっかり明るくなってからの観測だが、北極方面のリムの明るさの違いが、次第にはっきりした。

穏やかそうに晴れましたが、火星撮影中に雲がやって来て、中途半端になってしまいました。

Mars is without doubts a challenging planets for us "northerners".
Thanks to goos seeing I managed to have a better color balance than with the OSC.
Mare Erithraeum is barely detectable upon the bright SPC.
