シーイングは少し良く、北極雲か冠は分かりませんが薄っすらしろいものがみえます。

透明度が悪く、あまり使った事の無いSoftwareGainを使い青波長も撮像したのですが、
酷いノイズだらけの画像となってしまったので処理は諦めました。カラーのみ報告します。

Here is a mars report performed last 29th with the 150mm refractor under average good images.
Brightenings at limb and terminator still there,〓on Chalce,on mare australe towards the terminator.
On Hellas bassin〓a white cloud covered strongly Iapygia towards〓to zen lacus lightly into the bassin.

The small disc still shows some details,a.o. the NPC in the north and
the clouds or haze over Hellas. Visually,bright Hellas is more striking
than the very thin NPC. There also seems to be haze at the prec. limb,
around the equator. Regions on both sides of Syrtis Major appear bright.

Seeing conditions were fair and I was able to use powers of x375 and x500 to examine the features on the disk:
・SPR quite bright,some vague details visible.
・Hellas quite bright on the prec. limb- the basin seemed to contain some bight clouds/mist.
・Syrtis Major also present on the prec. limb- interestingly the northern part of the feature seemed to be faint and indistinct,
perhaps due to the presence of evening clouds.
・Hellespontus dark,but Noachis which was present on the morning side seemed brighter (although not as bright as Hellas).
・Pandorae Fretum and Sinus Sabaeus seen- Deucalionis Regio brighter than the two.
・NPC quite bright and well defined,a darker band present immediately to the south of the cap.

Clear sky but quite windy.
Average seeing makes it hard work to piece the Maria together on a drawing.
No obvious signs of blue Northern Polar Hood,but a bright white strip at the Northern limb which I think is the exposed cap.
The terminator and the limb are both whiteish in the north.
Hellas is clouded as it approaches the terminator,this cloud merges with the〓SPH which is itself concentrated towards the south pole.

Two daylight images and one from shortly after sundown I took today.
Seeing was average in the afternoon and very good at the last image, which was taken by an even longer focal length.
Result is shown at 100 %. Hazy south, especially in the Hellas bassin. NPH weak today. P-limb clouds over Electra in the first image.
