解説（安達） NPHは今日も明るさが低い。Goは、鮮明な画像を報告してきた。特にニクス ・オリンピカ(Nix Olympica;125W,+20)の様子が良く分かる。肉眼ではほとん ど見えない理由がこの画像で分かった。中央に暗い点がある為に、明るく見え なかったのだ。(reported by 8 obsevers) The brightness of NPH is low today. Go has reported on a clear image. Especially,the appearance of Nix Olympica (125W,+20) is understood well. The reason hardly seen has been understood with the unassisted eye from this image. It did not look bright so that there was a dark spot in the center. (reported by 8 obsevers) FROM Makoto ADACHI -------------------------------------------------------------------------------------

The Tharsis region with it's volcanoes are prominent in this image. There are a lot of bright yellow streaks on the plain. Are these normal or are these dust storms?  Here's another image of Mars' Tharsis region on a night of perfect seeing!  [Christopher Go : Cebu Philippines]
Here are 3 images from last evening. Quite happy with these,especially the first which was taken just after sunset,with Mars only 32 degrees Alt - nice detail in bright Northern hemisphere around Chaos. Still my usual inconsistent colouring!

I used the data from an imaging session on Nov 28 on Mars,to improve my used technique to show subtle color differences better in the darker albedo regions.As noted before here,the color differences of the western and eastern parts of Syrtis Major are especially interesting.The western side seems to be clearly brown/yellow/reddish while the eastern side clearly has the general color of the large mares on that side of the planet.According to this observation,there are some places in this region with other subtle colors; as the southern part of Lapygia Viridis/northern edge of Hellas contains some green; the northern edge of the Sinus Sabeaus-arm seems to have a mix of green and brownish tints. The eastern edge of Syrtis Major is even derogatory colored at all,with a kind of cyan tint.As far as I can recognise,the patch of Nodus Alcyonius has more the color of western Syrtis,but is hard to tell with certainty at this difficult position angle.I give this another try at the next transit. 10 inch Newtonian & ATK-1HS @ f/35 LRGB)[バンディバ:オランダ] [Ralf Vandebergh:Neighbourhood of Maastricht Netherlands]
