解説（安達）/ Comment by Makoto Adachi
火星は、最接近が近くなり、かなり丸く感じるようになった。Clyde Fosterの観測を見ると、今までよく晴れていたAurorae Sinus
(53W,-10）付近の晴れ間が、ダスティーになって、黒く記録されにくくなってきている。この様子はGlauco Uri,Raimondo Sedrani,
Michael Karrerも記録している。リムに近くなると、霧の影響を受ける。また、模様を黒くするとわかりにくくなるが、明らかな傾向である。
Fattinnanzi Cristian,Michael Karrerは、Mare Acidarium (20~45W,+40~55）の雲の様子を非常によく記録している。阿久津弘明は
Ausonia (W235~270,-55~-20）からElectris (165W~190,-40~-53）にかけて、淡い直線的な明るいバンド（淡い）を記録している。
これは肉眼でも見えるものだが、やや白っぽいことが、画像 (stacked image)から分かる。
Mars is getting closer and feels pretty round. Looking at Clyde Foster's observations,the sunny days near Aurorae Sinus (53W,-10),
which had been sunny until now,have become dusty and are becoming harder to record black. This is also recorded by Glauco Uri,
Raimondo Sedrani and Michael Karrer. Closer to the rim,it is affected by fog. Also,if the pattern is blackened,it becomes difficult
to understand,but it is a clear tendency.
Fattinnanzi Cristian,Michael Karrer very well records the clouds in Mare Acidarium (20 ~ 45W,+ 40 ~ 55). Hiroaki Akutsu recorded
a faint linear bright band (pale) from Ausonia (W235 ~ 270,-55 ~ -20) to Electris (165W ~ 190,-40 ~ -53). This is visible to
the naked eye,but you can see from the stacked image that it is a little whitish.

I was up a bit too late to catch Mars at greatest elevation,and conditions were not that good.
Centred on the western extensions of Valles Marineris,with Solis Lacus upper right of centre.

Discrete condizioni atmosferiche ed altezza del pianeta sempre maggiore mi hanno permesso questa buona ripresa,
ottenuta sommando le immagini ottenute da 5 filmati da 4 minuti ciascuno.
Molti i dettagli interessanti,dall'ormai ridottissima calotta polare sud (in alto)
evidentemente frammentata alle velature attorno a tutta la parte attorno alla calotta nord (in basso).
Acceptable atmospheric conditions and an ever-increasing height of the planet allowed me this good shot,
obtained by adding together the images obtained from 5 films of 4 minutes each. Many interesting details,
from the now very small south polar cap (top) evidently fragmented to the veils around to the whole part around the north cap (bottom).

シンチレーションがあまり良くないですが、質が変わりました。以前は、揺れが酷い+小さな空気の塊が一緒に流れて、まともな像が得られませんでしたが、
やっと以前のような気流の流れのみに戻り、それなりな画像が得られるようになりました。大きくなりましたね。

I‘m a frequently reader/observer of your website.
It’s an excellent place for studying planetary images from all around the world. But until now I did not submit images.
This is the first one and I‘m not sure if this is the right way to submit. Enclosed please find my sharpest Mars until now.
Short moments of fair seeing between long unsharp periodes. Thanks to Emil Kraaikamp‘s excellent software Autostakkert“
the sharpest puzzle areas resulted in my best image until now.
In my opinion the one shot colour cameras of today can easily compete with RGB filter imaging.
1000 frames selected from 15.000. Imaging sequence 180 seconds.

extrem good,steady seeing,no wind.
