解説（安達）
　火星の南半球は夏至を少し回り、夏本番となった。南半球の明け方のエッジ
や北極方面に白雲がはっきり見えるようになった。北半球はアエテリ
ア(Aethria;240W,+40)の暗斑は今回も非常にはっきりしている。ただ、白雲に
覆われることが多く、肉眼ではとらえにくい。Damian Peachの画像は細部が非
常に良く分かる。また、北半球の暗斑が霧に覆われている様子が良く分かる。

The summer solstice passed, and the southern hemisphere in Mars became
a real thing in summer. It came to see white clouds in edge and an
Arctic district of the dawn in the southern hemisphere clearly. The
northern hemisphere is very clear of dark pattern of Aethria (240W,+40)
this time. However, there are a lot of being covered with white clouds,
and it is not easy to capture it with the naked eyes. As for the image
of Damian Peach, the detail is understood very well. Moreover, the
appearance from which spot of the northern hemisphere is covered with
the fog is understood well. (reported by 5 observers)

  最近夜半前までは快晴なのですが、夜半過ぎには雲が出ます。
今回もそうで、仮眠後準備を始めると雲が出始めました。そのため
光軸調整が途中でしたが撮影を始めました。シーイングも少し悪く、
使えるのはこのコマだけでした。その関係で単色光の撮影は出来
ませんでした。薄雲を通しての撮影です。

Result of the observing session from Aug 23.
The remarkable difference in blue and IR images of the Propontis Complex seems to be caused by a yellow spot
which is easy visible on the IRGB image.It is arrowed.


Attached are 2 observations from Aug 23 observing session taken in near infrared 670-1000nm and blue light.
The difference in details is shown in this 2-frame animation.
We see the region of Mare Sirenum with Electris,Eridania and Ausania and Mare Chronium
Olympus Mons is exactly at the terminator and just not visible.Note the difference in Propontis Complex
between IR and blue image,as well as the difference in the SPC shape and size.

Seeing was poor-fair.
Some interesting detail present in all filters. Red reveals Trivium-Cerberus as its now well known two dots
appearance (also seen on the last presenation of this area in July.) Its, along with the dusky marking of 
Styx-Phlegra along with the dark Hyblaeus extension surround the entire Elysium area and looks like a light 
circular patch. The SPC can hardly be seen at all in Red at these longtitudes.

In Blue a morning limb haze from the souther polar haze right down to a bright NPH. It is brightest across 
Eridania and Ausonia across Mare Cimmerium. 

Also note the condensations in the Valhalla marking, especially in B and G.
