解説（安達）
夕方のリムではヘラス(Hellas;290W,-50)が明るく見えているが、ダストス
トームではなく、砂漠の表面が見えているようだ。アキダリウム(Mare
Acidarium;30W+50)付近は白い雲に覆われている。Damina Peachの画像ではニ
クスオリンピカ(Nix Olympica;125W,+20)が、暗い斑点に記録された。青画像
で暗い。このことから赤っぽい色であることが分かる。David Ardittiの画像
ではタルシス(Tharsis;90W,+10)付近が白っぽく観測されている。赤道付近の
夕霧のようだ。(reported by 5 observers)
It is not a dust roughhouse though Hellas (290W,-50) looks bright in
preceding limb in the evening. It seems to see the surface of the
desert. The vicinity of Mare Acidarium (30W,+50) is covered with a
white cloud. Nix Olympica (125W,+20) was recorded in a dark spot in
the image of Damina Peach. It was recorded darkly in a blue image.
It is understood that here is a color like red from this. The
vicinity of Tharsis (90W,+10) is observed like white in the image
of David Arditti. The evening mist in low latitudes.

Here are some images from this evening. Pretty good seeing,but very gusty easterly winds and lots of scattered low clouds with poor transparency above that due to high clouds.
Some interesting detail is seen now Solis Lacus has become visible. Arsia,Ascraeus and Olympus Mons are all seen as small dark spots in Red. Olympus also looks dark in blue. Brilliant clouds over Ophir/Candor. The SPH is bright with an extension of mist extending across Solis Lacus. The NPC edge is seen in red.

Managed to get Mars in very difficult, windy conditions last night in a thinning in the clouds at dusk. However, seeing was good. It shows that wind at surface level does not always equate to bad seeing - advertising the advantages of a dome, which I don't have.
Taken slightly earlier than Damian's, this confirms that Arsia and Ascreaeus Mons were showing as dark spots near the CM. Interesting that is is still possible to image these with the disk at 7.2" (focal ratio pushed to f74). Bright clouds, as Damian noted, also over S pole and Candor, N of Solis Lacus, near terminator.
