解説(安達)/ Comment by Makoto Adachi
Eric Sussenbach氏の画像は、白雲の様子をよく示している。SPCの東寄りは、薄く黄色くなった白雲が見える。低緯度地方のリムは
白雲で明るくなっている。北極は、Aetheria (240W;+40)とMare Acidarium (20~45W,+40~55)の北側で白雲の広がりがおお
Daniele Gasparri氏は、Arsia Silva Mons (W120,-3)付近の山岳雲を非常によく記録した。もう少し広く写ると、Pavonis Mons
(120W,+3)との関連が分かるが、範囲が少し足りなくて残念だった。しかし、今までのようにArsia Silva Mons (W120,-3)だけではなく
なってきたため、面白くなってきた。James Willinghan氏の青画像では、SPCからの白いにじみがほとんど見られない。このことから、
Damian Peach氏の画像では、Thyle IIのエッジダストストームの残痕の様子が、どのような状態になっているかを鮮明にとらえた
高尾氏の画像では低緯度地方に氷晶雲が見えている、Damian Peach氏の画像にも南緯20°あたりにかすかに見えている。

Eric Sussenbach's image shows the white clouds well. A pale yellow white cloud can be seen on the east side of the SPC. The low
latitude limb are brightened with white clouds. In the Arctic,the white clouds are widespread on the north side of Aetheria
(240W; + 40) and Mare Acidarium (20 ~ 45W,+ 40 ~ 55).
Daniele Gasparri recorded very well the mountain clouds near Arsia Silva Mons (W120,-3). If you take a closer look,you can
see the relationship with Pavonis Mons (120W,+ 3). This image was disappointing because the range was a little short. However,
it has become more interesting because it is no longer just Arsia Silva Mons (W120,-3) as it used to be. James Willinghan's blue image
shows almost no white bleeding from the SPC. From this,it can be seen that there are no white clouds outside the SPC. As a result
of image processing,a white cloud-like white bright part may be formed at this position,so be careful. Damian Peach's image is
a great image that clearly captures what the remains of the Edge Dust Storm on Thyle II look like. It can be seen that it is deposited
in a low place.
In Mr. Takao's image,ice crystal clouds are visible in low latitudes,and in Mr. Damian Peach's image,they are faintly
visible around 20 ° S.

Just  wanted to alert you that Mars was peculiar: the morning limb was bright with dust,
especially in Hellas (which just rotating into view… I followed the planet up until sunrise).
While it's not unusual for Hellas to be bright in the morning,the entire morning limb was bright yellow,
as was Isidis Planitia,which may also have been mixed with polar hood haze.
I confirmed this using a red filter.
Hellas and Isidid were still bright through a blue filter,
but the red filter brought out an entire crescent of intense cloud all along the limb.
Usually this is indicative of airborne dust.
We are still in the window for expected dust activity on Mars (predicted to end in the first week of September).
While nothing may come of this,I thought you might want to know in case you get further reports that something is brewing.

Another morning of good seeing. Conditions were cooler,but good seeing with heavy dew.
Possible brightening on the northern edge of Hellas.

in fair seeing conditions. Mare Cimmerium and Elysium area are in sight,
together with a bright polar hood and a vesperal orographic cloud over Tharsis.
There's also a thin cloud on western limb easier to see in blue light.

Here is a report of mars of last 6th september performed with the CC154mm.
Images were just average. The Amazonis veil seemed to fade.
Main features are visible in violet light.

Daniele Gasparri
Bright and extended orographic clouds are seen over the Tharsis region.

Here are a few images of Mars from the night of 5/6th September.
Seeing was poor due to swift moving jetstream across the image.
Tharsis volcanos visible with bright cloud over one peak visible in colour images.

The southern polar cap continues shrinking with visible features Syrtis Major,Hellas Planitia,Mare Tyrrhenum and Sinus Gomer.
