解説（安達）
ヘラス(Hellas;290W,-50)にかかった朝霧が顕著だ。この季節、アルギ
レ(Argyre;30W,-50)やヘラス(Hellas;290W,-50)などの南半球の盆地には霧が
かかるのが普通の姿のようだ。南緯45度付近の雲のバンドも顕著だ。１月２２
日にニロケラス(Nilokeras;50W,+30)の北隣にやや明るいスポットが見えてい
たが、今日も同じところに見えている。これは地形的なもののようだ。D.C.

The morning mist that hangs to Hellas (290W,-50) is remarkable. Be of
the fog usual in the basin in the southern hemisphere such as Argyre
(30W,-50) and Hellas like this season appearance. The band of the
cloud of about 45° south is also remarkable. Today is seen at the
same though bright spot was seen in the next of the north of
Nilokeras (50W,+30) a little on January 22. This is like the
geographical features one. D.C.Parker plainly records the cloud of
Arsia Silva(125W,-5). (reported by 8 observers)

珍しく 3/10程度のシーイングで、しばらく安定していました。
・ヘラス付近の雲(霧？ダスト？）がとても白く輝き、印象的でした。

This is an observation obtained on Jan 24,19:32-19:40 UTC
This evening provided actually a first good seeing since October(!!!) for Mars,thanks to high cirrus which
causes a very poor transparance for this session.
-Solis Lacus is recognisable in the blue light image as a dark center with an obvious bright area left from it.
The haze above Argyre is also visible well.
-The R(G)B color image shows a nice view of both the Nectar and the Vallis Marineris regions.
-Phoenicis Lacus looks elongated again.

Here are some images from Jan 24th. Good seeing. Note the bright cloud over Argyre. Also the SPH seems to extend someway northward along the terminator. The NPH is still very prominent at this longtiude with no sign of the NPC edge in red light.

Hi all,seeing was excellent on the 24th -
Argyre is still cloudy. The SPH is much weaker than the NPH at same season,I believe because the SPR miss the same quantity of water vapor,right ?
Ascraeus is again seen as a red spot in the morning.
The first sequence is taken with the Lumenera,the second one with the ATK. In that superb seeing,both cameras did the same job.

This is the best I have been able to do on Mars recently.
The Toucam was used at 30 fps for 1 min on R,10 fps for 3 mins on B.
Like other observers,I note that Argyre was bright in blue (clouded) at this time. Chryse,towards p limb,has bright patches in R. I am not sure of the reality of the diagonal line of dark spots,as they are not shown in other observers' images from this time.
