解説（安達）/ Comment by Makoto Adachi
≪神奈川県 横浜市 三品利郎≫[Toshirou.Mishina:Kanagawa Japan]
最初はシーイングがよく、非常によく見えた。南極部に非常に小さな光点があり、ＳＰＣのように見えるが、確信が持てないので、未記入。

≪滋賀県 大津市 安達 誠≫[Makoto Adachi:Siga Japan]
透明度高く、気流も安定していました。
≪愛知県 春日井市 伊藤了史≫[Satoshi Ito. Kasugai City,Aichi,Japan]
比較的いいシーイングに恵まれたので、視直径(5.6")の割には地表の模様がよく写った。
NPCと思われる極付近の白いエリアもはっきりと認められる。高度は高いが、後半はシーイングが低下した。
≪滋賀県守山市 森田光治≫[Mitsuji Morita:Siga Japan]
春の陽気と高度が高かったこともありかなり安定したシーイングでした。
とは言っても5秒角ディスクの細部はなかなか解りません。

Here is a mars report of last 23rd march performed with the 127mm edt apo.
Images were rather good at the beginning of the session.
Brightenings were noted:
on argyre terminator side,
on Juventus Fons until the Chryse Xanthe channel on the terminator side,
on the edge of Hellas basin on the limb,
on Syrtis Major on the limb,
on the north cap region,a white condensation under Mare Acidalium,withish under Ismenius Lacus,
on Mare Australe a withish region.
The Moag-Arabia region appeared cleared until Eden region (probably a ground reflectivity).
Sinus Meridiani and Sinus Sabaeus appeared poorly contrasted (but in the 127mm).
The seeing get poor after 19H30UT,with 5/10 and less.
[Stanislas Maksymowicz Ecquevilly,France]
Average seeing becoming better with time. Haze at the morming terminator,rest of NPH extending into it.
Maybe separate cloud band south of NPC/H (first image,not very apparent in RGB,but in B).
Chryse looks bright,too (in R,G & B),Acidalium/Niliacus appear very dark.
In the south,clouds/haze over Argyre rotate into view,becoming very prominent in the last image.
Presumably also haze around the south pole (faint).

好Seeing ではあるが透明度が今一つで眼視では北極付近が白っぽい感が在るのですが・・・・、
南の Cimmerium から Syrtis に至る模様は濃く見えていて、Cerberus 付近も模様が確認できました。

≪愛知県稲沢市祖父江町 尾崎公一≫
Seeing conditions weren't quite as good as on the previous night but still good enough to use a combination of x375 and x600.
The results are much the same as the 22nd and are as follows:
・SPR once more quite bright.
・Erythraeum again shows some interesting structure with Margaritifer Sinus appearing marginally darker than Auorae Sinus
(although this was much closer to the fol. limb than on the 22nd)
・Pandorae Fretum seen,and darker than the nearby Deucalionis Region immediately north.
Sinus Sabaeus and Sinus Meridiani can be seen.
・Acidalium again quite prominent but tonight Chyrse didn't appear to be quite as bright.
・NPC quite bright and again a darker band present just south of the NPC.

[Shigeru Kurisu,Mitoyo Kagawa,Japan]
Only one image from the evening of March 23rd,
because seeing was usefull only over a comparably short period.
Prominent NPH, seems to cover about half of Mare Acidalium with mist.
Some haze in higher southern latitudes.
