真冬のようなシーイング。画像処理でようやくSPCが出てきましたが、撮影時のモニタ上では、ごく時たまチラリと見える程度でした。
詳細は全く写っていませんが、記録として報告いたします。

B−390は、15h32mはビニングをしてみました。大きさは半分になりましたが、コマ数が倍になり、処理を弱めたのに、コントラストの付いた画像になりました。
Bの画像で見ると、大シルチスとサバ人の湾の間に、薄雲があるようです。サバ人の湾と子午線湾の間も、雲があるのか切れて見えます。

Stanislas Maksymowicz
Here is a report performed last 23rd with a simple 110mm cassegrain with just good images (7/10),excellent sky transparency.
Tiny south polar cap with dark border discontinuities.
North polar hood present still covering the edge of the planet.
Brightenings on the terminator,the Tharsis volcano but also on the Solis Lacus end,Daedalia. Both bright under the W11 and W80A filters.
Brightenings on the limb area,Moab and Sinus Sabaeus covered by the veil but not occulting. Both bright under the W11 and W80A filters.
The background color exhibited a pale milky yellowish orange tint. The planet color in sky was still yellowish.
However the south cap area seemed to be clearer with a usual ground color: is that showing the beginning of the atmosphere clearing from dust?
I didn't push further the session as the seeing after 22H00UT became worst.
Globally the contrasts level standed rather low than usual.
The north hemisphere on its northern parts exhibited rather the lowest contrasts,Niliacus Lacus,Mare acidalium and Nilokeras,lower than ususal.

This was acquired some time before the dark streak was visible.
Interesting to note the cloud activity in much of the South-West (lower left) quadrant of the planet,best visible in the B filter image.

Charles Galdies
Blue clouds over Daedelia and Mare Acedalium. This observation session showed blue clouds on Mars,
located over Daedelia and Mare Acedalium.
These two areas are often characterized by the presence of similar clouds.
Similar clouds often appear along with white clouds and mists,
but blue clouds probably occur at higher altitudes.
Blue mists also appear quite commonly over the terminator at sunrise,and sunset in the equatorial belt.
Observations suggest that these type of clouds are relatively high in the Martian atmosphere,estimated to be around 15 to 25 kilometers.
