解説（安達）/ Comment by Makoto Adachi
Argyreの南のＳＰＣは晴れている部分が小さくなった。一方、Hellespontus付近は大きさに変化はない。Aonius北方のＳＰＣの
晴れ間も小さくなったように見える。
Meridianiの北の光斑は、今日も記録されている。Mare Acidariumの北側はかなり晴れてきて、黒く観測されている。Hellasは
昨日と同じように、今日も赤っぽい。
Solis Lacusの北東部に小さく明るいダストストームが発生した。Clyde Foster氏やAntonio Lasala氏の画像に、鮮明に記録している。
しかし、時間とともに明るい部分の変化を調べると、微妙に位置がずれている。
最初は、Christophe Pellier 01h04m ダエダリア中央の東側
John Sussenbach 02h50m ダエダリア中央の東側
Clyde Foster 21h09m ダエダリア北端
Antonio Lasala 23h16m ダエダリア北端からやや東へ
ほぼ1日での位置の変化が見られる。
The sunny part of SPC in the south of Argyre got smaller. On the other hand,there is no change in size near Hellespontus.
The clearance of the SPC north of Aonius also seems to be getting smaller.
Light spots in the north of Meridiani are also recorded today. The northern part of Mare Acidarium has been sunny and observed black.
Hellas is red like today as it was yesterday.
A small and bright dust storm occurred in the northeastern part of Solis Lacus. It is clearly recorded in the images of Mr. Clyde Foster
and Mr. Antonio Lasala. However,when examining the change in the bright part over time,the position is slightly shifted.
Initially
Christophe Pellier 01h 04 m East side of the center of Daedalia
John Sussenbach 02h 50 m Eastern side of the center of Daedalia
Clyde Foster 21h 09 m North Edge of Daedalia
Antonio Lasala 23h 16m Slightly east from the northern end of Daedalia
（by 8 observations ;reported by Makoto Adachi)
-------------------------------------------------------------------------------------
The full image set from yesterday evening. Other than the small outbreak in the Solis Lacus region,a few other things I note:
- The limb brightening continues and appears to also have a G component.
- M Acidalium is showing as very dark
- The NPH(I hope that is accurate),in the last few days seems to have significantly reduced in brightness,
and it appears that some structure may be detected as a dark area in the R image
I captured a fair bit of data last night,but with Nick Haigh reporting an outbreak in Daedalia,
I did a very quick process of my last capture of the evening and it indeed shows the storm in the Solis Lacus/Daedalia region at upper right.
This region has been very active throughout the duration of the main storm.

Here are my Mars results from my visit of the IAS observatory in Namibia July 25th 2018.
In the second half of this night the seeing conditions getting worse.
Still have to process about ten more days of observations from this visit.
