相変わらずシーイングが良くなく、
火星像はグニャグニャのブルブル状態です。
アギダリアの北部に雲か霧が発生しているのかも。

シーイングは安定しません。
初め見えていたHELLASとSYRTIS MAJORは、沈んでいきました。
北極冠の右側に２つの白雲（？）が目立ちます。

北極冠近くの雲は活動的ですが、その周りが赤紫色（色は微妙です）に写りました。

I had a look on Mars yesterday evening with a window of 2 hours using the
254mm cassegrain.
In first,looking at Mars with naked eyes,it appeared also yellowish and
not the orange-red usual color.

I used the 254mm cassegrain for the report performed at 238x,more was not
possible (the 312x too blurring with the seeing). The overall disk color
was not usual and I confirm my observations of the 3rd with some adds,
considering the observation in IL.
Generally,for all channel color observed,especially the red,the contrast
levels are poor. Mare around Solis Lacus,Aonius,Sirenum were almost
un-perceptible. Mare Boreum around the cap was not conspiscious. All the
half tones features represented on the temperate area looked very low
contrasted,Nikokeras and surroundings too,Elysium at the limb whitish
with dark boundaries looked also low contrasted (seemed reinforced by the
transition white dark boundaries,etc...
The best views were under the blue filter (relatively),and exceptionally
poor in contrast under the red filter,the yellow at a lesser intensity.
Indeed the sketches seems to show hard contrasts,enhanced here for showing
the difference between colors.

I remembered the vision of Syrtis Major during the great dust storm where
it disappeared almost. I saw it in spite of in the 100mm refractor when its
contrast was around 3% only. This was near a limit. Here on the 7th May,
yesterday,we can attribute a level contrast of the features staying on the
temperates zones to be say 5% more or less.
I we try to attribute a density of atmosphere attenuation,this could be
minimum 50% (those features under clear atmosphere turn around 10% level).
The tendency,stronger in red color surely.
Therefore in addition to the white hazze we see due to season occurences,
there is an amount of dust with a non-negligeable density.
This is a fact.
Where is coming this dust:
- cap thawing speed very high,sothat dust are transported by the white
hazze,
- deep white clouds at equator limbs crearing strong convections from the
ground (we saw in yellow-red colors patches of bright ground area when
white clouds disappeared).
Interresting to follow.
