解説（安達）/ Comment by Makoto Adachi
今日も南極冠の西側に白雲が顕著に見える。西経20°付近に光点が見られ、そこから北に向かって白雲が広がっている。小規模だが、
Miguel Araujo氏がこの様子を記録している。一方、西経170°くらいの南極冠の周辺にはそれよりもきぼの大きなものが見られる。
これは、大田 聡氏・Milika-Nicholas氏が記録された。
6月26日に南極冠の上に見られたダストストームのプロジェクションは今日も見られ、
Efrain Morales Rivera氏がR画像でその様子を
記録している。
西経75°の南極冠付近では北に伸びた暗いバンドが記録されている。（Efrain Morales Rivera氏）また、Hellespontus付近にも顕著な
縦じまが見られる。（Johan Warell氏）これらは、南極冠からの冷気の吹き出しによる晴れ間である。Damian Peach氏は、その様子を
克明に記録した。南極冠から小さな吹き出しが5〜6本見ることができる。ダストストームは上空に、冷気は地表を這うように覆って
いる様子が、非常によく出ている。
ダストストームは西経200°付近で、かなり活発な様子を示している。
Blue clouds are remarkable on the west side of the SPC today. A light spot was seen in the vicinity of 20 ° west longitude,from which
the white cloud spreads northward. Although it is small scale,Mr. Miguel Araujo records this situation. On the other hand,around the SPC
around 170 ° west long,bigger ones can be seen than that. This was recorded by Mr. Satoshi Ota and Mr. Milika-Nicholas.
Projection of the dust storm seen on the SPC on June 26 was also seen today,Mr. Efrain Morales Rivera records the situation
in the R image.
A dark band extending north is recorded near the SPC of 75 ° west longitude. (Mr. Efrain Morales Rivera) In addition,remarkable vertical
streak is seen near Hellespontus. (Mr. Johan Warell) These are sunny days due to cold air blowing out from the SPC. Mr. Damian Peach
recorded the situation in a clear way. You can see 5 to 6 small speech bubbles from SPC. It seems that the dust storm is over the sky and
the cold air crawls so as to crawl on the ground surface very often.
The dust storm shows quite lively appearance around 200 ° west longitude.

Comments :
Sketch and Watercolor of Mars (black pen HB and blending stump on white paper plus watercolor) made with my Mewlon 250/2500.
I add a winjupos simulation to see if I detect some topics,but it's sure,the dust tempest is dense!
[Michel Deconinck : [Artignosc-sur-Verdon,France]]
Mars still under strong dust storm,today only sublte details can be see from surfasse.
The SPC has one curious format with one extension to the right side
[Guilherme Grassmann,Americana-San Paulo,Brasil]
Here is the Mars report of the 27th June performed with the 130mm Cassegrain Under poor to average images.
Still low to very low contrasts were observed,polar cap whitish ocre.
Difficult to say more with regards to the conditions;
[Stanislas Maksymowicz Ecquevilly,France]
Seeing: 7/10,Transparence: 7/10

Under better conditions than the night before,still with clouds on the northern polar area,and on the limb south,
and more interesting with the dust storm which arrived on South polar area,partially covering it.
[Marc Delcroix Tournefeuille,France]
Under dense Saharra dust aerosols.
[Efrain Morales Rivera Aguadilla:Puerto Rico]
Some moments of decent seeing at times. Sadly there is not much to see really,
aside from the peaks of the Tharsis volcanoes sticking through the thick dust layer!
[Damian Peach: Loudwater,Buckinghamshire,United Kingdom]
Mars transits at less than 12 degree altitude
from here so the conditions are difficult with constant heavy turbulence,
the seeing has generally not been better than 2/10.
[Johan Warell:Lindby:Sweden]
An rgb as well as several "iR" filter types which do seem to "penetrate" the dust somewhat...
