解説（安達）/ Comment by Makoto Adachi
火星面は、ダストの少なくなってきたところが広がってきている。地図を見ると、高地になっており、ダストの高さを反映している、
Clyde Foster氏の画像には、SPCの北側に黄色いダスト色の明部を記録している。一見してダストストームのように見えるが、8月31日
のKev Wildgoose氏の画像と比べると、全く同じものであることがわかった。これはエッジダストストームの残痕である。
Giancarlo Rizzato氏は白雲に焦点があるようで、午前半球の白雲の広がりがよくわかる。眼視観測ではここまで淡いものは見えてこ
ない。これがコンスタントに撮れれば、氷晶雲のいち早いキャッチができるだろう。
日本では、Aurorae SinusやSolis Lacus付近が
観測できた。この地域は全体がかなりダスティーであるが、Stack onlyの画像を見ると、その様子がよくわかる。伊藤氏の画像では南半球の
様子や、画像中心地域が淡くなっている様子が判断できる。このような報告は、ダストの広がりをつかむうえでありがたい。
Maximilian Teodorescu氏はArsia Silva Mons (W120,-3)から東に延びる帯状の雲を記録した。よく記録される雲とは反対方向である。
これがArsiaの山による、特徴的は帯雲かどうかは即断できない。山によってできた雲と、Arsiaの東にできた夕霧が合体した姿に見え
なくもない。結論を出すには、探査機の画像がほしい。（9月7日のDaniele Gasparri氏の画像を参照してください）
The surface of Mars is becoming less dusty. Looking at the map,Clyde Foster's image,which is highland and reflects the height
of the dust,has a yellow dust-colored bright area on the north side of the SPC. At first glance,it looks like a dust storm,but it turns out
to be exactly the same when compared to Kev Wildgoose's image on August 31st. This is a remnant of an edge dust storm.
Giancarlo Rizzato seems to focus on the white clouds,which clearly shows the spread of the white clouds in the morning hemisphere.
Nothing so faint can be seen by visual observation. If this can be taken constantly,it will be possible to catch the water ice cloud quickly.
In Japan,the vicinity of Aurorae Sinus and Solis Lacus could be observed. The whole area is pretty dusty,but the Stack only image
shows it well. From Mr. Ito's image,it can be judged that the state of the Southern Hemisphere and the state of the image center
area are fading. Such a report is grateful for grasping the spread of dust.
Maximilian Teodorescu recorded a band of clouds extending east from Arsia Silva Mons (W120,-3). It is in the opposite direction
to the well-recorded clouds. It cannot be immediately determined whether this is a characteristic band cloud due to the mountains
of Arsia. It can be seen that the clouds formed by the mountains and the evening fog formed to the east of Arsia are united. To make
a conclusion,I want an image of the spacecraft. (See image of Daniele Gasparri on September 7th)

I've been keeping away from combining morning and evening sessions due to a few health issues,
but felt good enough to give Mars a crack this morning. Nice to see it getting to a significant size,
and there appears to be quite extensive cloud over the planet,particularly in the north polar region.

Attached is a observation of Mars I made last night in average seeing.
Even in Ant III,there is a lot of detail to be seen,and my impressions are as follows
- The SPC was harder to make out at this longitude.
- The brighter deserts of Phaethontis,Electris and Eridania were visible-
I don;t think there was much bright cloud activity in these regions.
- A lot of details present in the Mare Sirenum and Mare Cimmerium,
both had irregular northern boundaries and the regions immediately north were bright in places.
- Elysium seen near the morning terminator but it was particularly bright or noticeable,
- Northern limb bright and bluish in colour,the following limb was also bright but not as brilliant as last time I observed the planet.

I had to use IR750 for red due to the seeing conditions,and so there is not much detail in Green or Blue.
The south polar cap is visible at the bottom and some blue cloud at top on the limb.

In very poor seeing. Note the elongated cloud in the blue filter image,near Arsia Mons.

Here is a report of mars on 4th september drawn with the 100mm refractor.
Relative good images and sky transparency on the session before the sky closure by clouds.
Atmospheric veils still present at the limb and the terminator.
The martian atmosphere keeps clear on the blue channel mainly.

These are taken with 2 minute R and IR videos,and 1 minute G and B videos.
Seeing has actually been pretty poor,with something of a northerly airflow of late.

Several Mars images from Sept. 4th in mediocre seeing but decent outcomes:
we were trialling using the new ASI42MC as well as using it to set the ADC for the mono 290MM...swaping cameras after setting it to use the mono ASI290MM,
to compenate for the low elevation that Mars is in Sth. Australia this year.
The 462MC appears to compare very well with the mono 290MM,although we always like to obtain the mono single-channel images.
