解説（安達）
Stanislas Maksmowicz は、肉眼観測でも北極フードの複雑な姿を捉えている。
パンカイア（Panchaia；220W,+62)付近に雲の濃い部分ができているが、肉眼観
測でも見えていたようだ。プロポンティス（Propontis；180W,+45)の２つの暗斑
がはっきりと記録され、ダストは落ち着いてきた。オリンピカ（Nix
Olympica;135W,+25)が青画像で写りにくくなってきたことから判断できる。これ
らの様子は、Pete LawrenceやDamian Peachの画像によく表現されている。
Damian Peachの画像では、アルシアシルバ(Arsia Silva;125W,-4)を横切る雲が
観測されている。(reported by 5 observers)
Stanislas Maksmowicz has caught the complicated figure of the North Polar hood
also visual observation. Although the deep portion of clouds can be seen
near Panchaia(220W,+62), visual observation also seems two dark spot of
Propontis (180W,+45) are recorded clearly, and dust settles down and is
visible. It can judge from Nix Olympica (135W,+25) becoming difficult to
be reflected by a blue image. These situations are often expressed in
the pimage of Pete Lawrence or Damian Peach. The clouds which cross
Arsia Silva (125W,-4) are observed by the image of Damian Peach.

I have increased my image scale in these by stacking an AE 1.6x Imagemate with a
Televue 3x Barlow. Composites are (IR)GB with an IR luminance. They seem to have
gone rather green round the gills - a queasy Mars. Probably too much wavelet
sharpening of the G channel is responsible.

While doing some DSO imaging last night I managed to find some time to process another of my captures from the 18th. Unfortunately I may have a bit more time to catch up soon as my telescope's drive controller went up in smoke this morning - a couple of kind souls are trying to get me up and running again though.

under fair seeing.
Lots of interesting details across this hemisphere. Note Elysium Mons seen as a bright spot and also likely Hecates Tholus as well just to the north. Interesting details around and under the NPH. Note in Blue Light the dusky line connecting Hyblaeus with the tip of the "Valhalla" marking. Also note the new extended Hyblaeus extension is seen in Blue light connecting to Tritonis Sinus. Styx-Phlegra is also dark in Blue.
