解説（安達）
今回の観測ではオリンピカ（Nix Olympica;135W,+25）が目立っている。色を
強調すると赤くなり、ダストベールの影響を強く受けているのがわかる。青画像
で黒く見えるということは下降気流があると考えられる。アルシアシルバ(Arsia
Silva;125W,-4)も、同じことが言えるが、山の高さが低いため、オリンピカ
（Nix Olympica;135W,+25)のような顕著な姿にはなっていない。
(reported by 7 observers)
In this observation, Nix Olympica (135W,+25) is conspicuous. If a color is
emphasized, it will become red, and it turns out that it is strongly
influenced by dust veil. It is thought that it looks black by a blue
image has a downdraft. Arsia Silva (125W,-4) can also say the same
phenomenon. Since the height of a mountain is low, it is not a
remarkable figure like Nix Olympica. (reported by 7 observers)

These are from a poor seeing night. Olympus is prominent on the terminator, as
are two of the Tharsis volcanoes in the upper image. The NPH is very blue. The
second blue image suffers from an unfortunate dust ring artefact. This arises
because the new Astro-Physics 1200 mount holds the planet in one place on the
chip so accurately that any blemishes are not smoothed out by drift, unless one
moves the image deliberately.
