 ヘラス(Hellas;275~315W,-30~60)付近のダストストームは、次第に拡散してきたようで、ヘラス(Hellas;275~315W,-30~60)の輪郭が
下に透けて見えてきた。しかし、ヘラスの西側は、広い範囲で寝ぼけたような見え方になっている。メリディアニ（Meridiani;0W,-5）の
南西隣に、かなり明るい部分が記録されている。カラー画像だと白く写っている。青画像でも白くなっているが、注目されるのは黄色画像で、
非常に明るく記録されている。また、赤画像でもIR画像でも明るくなっている。単なる朝霧ではなさそうだ。残念ながら、この日の数日
後は、この地域の観測がなく、詳しい様子はとらえることができなかった。

The dust storm near Hellas ( 275-315W,-30-60) seemed to be spreading gradually,and the outline of Hellas ( 275-315W,-30-60) was
seen through below. However,the west side of Hellas looks broadly drowsy. A very bright area is recorded to the southwest of
Meridiani (0W,-5). It is white in color images. Although the blue image is white,the yellow image is noticeable and is recorded
very brightly. In addition,both the red image and the IR image are bright. It's not just morning fog. Unfortunately,a few days later,
there were no observations in the area,and no details could be captured.

-------------------------------------------------------------------------------------

I just managed a single capture of each channel before clouds closed over this morning.
It appears that Hellas is already losing its winter coat. There appears to be a few scattered clouds,
but most notable is a bright cloud on the southern edge of S Meridiani at upper right. Syrtis Major centre left.

Good seeing on the 21st allowed for a nice view of the Chryse/Acidalium/Solis Lacus hemisphere. All looked normal for the season.
