解説（安達）
 アキダリウム(Mare Acidarium;30W+50)付近は、広く白雲に覆われ

らしく、コントラストが低く写っている。アルギレ(Argyre;30W,-50)

記録している。ヘラス(Hellas;290W,-50)のやや東側に明るい部分が記録

The vicinity of Mare Acidarium (30w+50) seems to be covered with
white clouds widely,is low contrast,and reflected. Argyre (30W,
-50) is recorded barely brightly. Carlos Hernandez clearly records
NPC. A bright part is recorded on the east side a little,and it
is here about Hellas (290W,-50) the possibility that white clouds
have been generated.

I made an observation of Mars on March 27,2006 (00:40 and 01:00 U.T.) under good seeing (6-7/10) seeing conditions. Although subtending an apparent diameter of only 5.9 arc-seconds I was able to make some detail over the Martian surface and atmosphere. I welcome any comments that you may have on my observation.

Notes:

00:40 U.T. (Left image,CM 290.2,Klee OPS Barlow): Syrtis Major (3-4/10) and Iapygia Viridis (4/10) were visible on the CM. Mare Tyrrhenum (3-4/10) and Syrtis Minor (4/10) were noted towards the preceding limb. Hellas appeared as a shaded to bright (6-7/10),oval feature preceding the CM towards the south-preceding limb. Hellespontus (3-4/10) and Pandorae Fretum (4/10) were visible towards the south-following limb. Sabaeus Sinus (3-4/10) was visible towards the following limb. The North Polar Cap (NPC) was brilliant (10/10) and visible over the northern limb.
01:00 U.T. (Right image,CM 295.1,W38A): Bright to extremely bright (7-8/10) aerosols (clouds?) were visible over Hellas and the preceding limb. The northern,morning (following),southern,and evening (preceding) limbs appeared extremely bright (9/10). The NPC was brilliant (10/10) over the northern limb.
