解説（安達）/ Comment by Makoto Adachi
The seeing has been very good indeed over the past two nights in particular. Great views of the Red Planet!

Attached are three drawings I made on the night of 21st-22nd September. We had very good seeing here (around AI-II) which lasted pretty much for most of the night.
I was able to examine Mars at powers of x600 and I had some of my best views of the Martian surface and saw details I had not seen previously:
- SPC small but still easy to see at these longitudes.
- Sinus Sabaeus was the darkest feature on the disk- especially along some of it's northern sections.
Edom was bright as was the region immediately north of Sabaeus.
- Pandorae Fretum fairly well defined and some interesting structures present. In Drawing 1,the Hellas basin is on the prec.
limb but was not particularly bright. The deserts of Noachis,Argyre I and II were dusky and not particularly bright.
- Erythraeum showed a lot of structure- I have often been intrigued by Antoniadi's statement of how Martian details can break up into a myriad of fine points- this was definitely the case in Erythraeum!
- There seemed to be rather bright clouds present just east (left in the drawing) of Margaritifer Sinus and also in Chryse and Ophir.
- Niliacus Lacus,Acidalium and Nilokeras seen 'emerging from the clouds' of the north polar hood.
- Interestingly,the clouds over the northern limb were notably bluish tonight,as were those on the following limb-
clouds on the limb usually appear white to me,but there was a bluish tint to them last night.

Found some slightly better data taken earlier on during this session.
Obtained using the new C14 telescope from here at home. Solis Lacus/Chryse/Valles Marineris on view.
Chryse and Solis Lacus on view. North polar hood is prominent at bottom.

Seeing 9/10 Trans 8/10,Verry good and stabil seeing conditions.

Here is a mars report performed with only a 50mm refractor F12
under almost fixed images and a relative transparent sky.
The main features appeared very clearly,argyre bright,hellas clear,syrtis major,
sinus sabaeus and sinus meridiani appeared contrasty.
Margaritifer sinus was still occulted by a consistent〓hazze〓standing at the limb.
Polar hood at the north,the Lybia〓area looked bright also on the terminator.
In spite of its tenuous size the south cap was there and well resolved as a white dot,stellar appearance,
a light hood close to the south cap was accessible.
The session was stopped by the clouds coverage,
I didn't had enough time for the filter color analysis of the veils in presence.

Very poor seeing,but western border of Hellas (Mare Hadriacum) is very ill defined.

incredible good seeing,like yesterday,too. No wind,high humidty and a very slow Jetstream.
[Silvia Kowollik Ludwigsburg,Germany]
Seeing 8/10 Trans 7/10
Seeing was slightly above average with average transparency.

Here then my observation of Tuesday (9/22) in the early morning.
You see a lot of cloud around the North Pole (you can see this clearly on the blue observation) and morning clouds on the edge of Mars.
The South pole is getting smaller and smaller.
Telescope C14,camera Basler 640,Chroma RGB filters and 1 degree dispersion wedge.

In fair seeing. Note the cloud on the terminator better seen in blue.

Good conditions early on 22nd Sept. Possible cloud/haze on the LHS of the disc.
