[jamsat-bb:15125] AO-40 Update, 2004-05-11
JJ1WTK 坂本です。
5月11日付けで W4SM, Stacey Mills が amsat-bbに書いていた
AO-40 Update を紹介します。
----
下表に示すとおり、AO-40の姿勢は、いわゆる「なぞの力」の影響により
ALONの値がかなり大きくなっているはずです。そのため、状況が改善する
7月の初〜中旬まではAO-40との間で通信を試みることは殆ど無意味と思われます。
7月下旬にスクイントアングルがかなりよくなる時期がありますが、
その時期はソーラーアングルが極めて悪いのが残念です。
今後の情報にご注意ください。

As the table below demonstrates, the "mystery effect" has taken A0-40 into
highly unfavorable ALON. Attempts at communication are likely to be futile
until conditions improve in early and mid July. Note that unfortunately
optimum squint in late July corresponds with a very bad solar angle.
.stay tuned.
