解説（安達）/ Comment by Makoto Adachi
雲の晴れ間から撮影開始したものの1枚で曇ってしまいました。
暫く待ってから来た次の晴れ間は気流が滅茶苦茶で諦めて撤収しました。

Here is a mars report performed last 18th april with the 235mm cassegrain.
Images were average only to poor.
Brightenings for the brightest are plotted against the main feature.
An equatorial haze seemed to be there but to be confirmed
(mention ? on the sketch drawn with the blue filter).
[Stanislas Maksymowicz Ecquevilly,France]
The run of clear nights with good seeing continues.
Attached is an observation of Mars made yesterday- the only prominent marking on the disk is the Mare Sirenum.
Elsewhere there were vague markings,particularly in the deserts to the north.
[Paul G. Abel:Leicester:United Kingdom]
Just average seeing. Mars presented a fairly featureless disc most of the time.
With hard work, soft impressions of the maria, NPC, and SPH could be captured, along with some cloud activity;
Two diagonal streaks of cloud running from the limb to two of the Tharsis volcanoes.
A darkish half tone smear at Olympus Mons, and some morning mist over Amazonis.
