今日もダストベールの影響が大きく、HellasからSyrtis Major南部にかけては非常に不鮮明な姿になっている。また、南極フードは
ダストベールが凝結核になって白雲が大きく成長しているのではないかと思われるような姿を示している。大杉氏の画像では、このHellas南部や
Syrtis Major付近が黄色くダスティーになっている様子をリムで記録している。Eric Sussenbach氏の観測では、低緯度の氷晶雲が良く
記録されている。Mare Acidariumの北方には白雲が広がっている様子を記録している。
The influence of the dust veil is great today,too,and it is very unclear figure from Hellas to the southern part of Syrtis Major. Also,
the Antarctic hood shows that it seems to be thought that dust veil becomes condensation nucleus and white cloud grows big. In the image of
Mr. Osugi,this rim recorded the appearance that this southern part of Hellas and the vicinity of Syrtis Major are yellow and dusty.
According to Eric Sussenbach's observation,low latitude water ice clouds are well recorded. The northern part of Mare Acidarium
records the appearance of white clouds spreading.

Despite Meteoblue projecting very poor seeing conditions,
I was up a bit earlier to try and catch the polar storm on Saturn,
so Mars was at a lower altitude for these captures.
Some cloud and two dark spots appear to be in Hellas,a
lthough it also appears that there is a section of the basin that is clear of ice/cloud

Catching up on some unprocessed data. Here is Mars on April 15th under very poor seeing.
