快晴の空であるがシーイングは最低でした。シルチス見えるだけした。

夕刻、北から湧き始めた雲に全天覆われた後の晴れ間。シーイングは昨夜とあまり変わらず良くありません。

Here is a mars report of last 20th jan performed with the 305mm cassegrain.
Images were average but workable with a transparent sky.
Still the same cloud on the argyre- edge of noachis. The argyre contour appeared slightly through the cloud,not thick.
Veils,clouds are plotted on the sketch.
The south hemisphere appeared more misty so that the feature contrasts were lower than usual.

Despite the shrinking diameter,the seeing was good enough to allow some good detail to be seen.
The NPC appeared to have a faint dark band showing through at its boundary,
There was dull mist on the western side extending onto the disc from the morning terminator,both to the north and to the south of the equator.
Agathodaemon was well seen,Phasis was not visible,I think obscured by mist.
The eastern limb was bright with mist all the way from pole to pole,especially so at Chryse where it extended a little along the equator. I did not notice Oxia Palus,perhaps it too was obscured by mist.
Lunae Lacus and Ganges were both visible in the better moments,and Ophir-Candor appeared bright and golden.
Argyre was bright with cloud.

Another evening with good seeing. Lots of detail despite shrinking disk.
Interesting clouds swirling around the north pole, still covered by the NPH.
Constant haze in Argyre Planitia. Last image under worse conditions.
