<P>最近近所のコンビニが突如閉店した。近くに道の駅ができる予定＆道路の拡幅で仕方ないが、観測前の買出しにとても苦労する。ついでに絵皿のポイントシール集めにも支障がでることは間違いがない。歩いて５分のセブンイレブンが車で５分のミニストップとなってしまった。</P> <HR size="1"> <H3>■観測結果</H3> <TABLE border="0" width="480"

８月下旬以降台風一過でも夜になると雲が増える状態だったが、約３週間ぶりに晴天となる。観測中の風景も様変わりして、虫の声と東に高いオリオンがめだっていた。流星活動では掴みどころのない９月ペルセウス群が活発で、輻射点報告したもの以外にも各所で群活動を感じさせる。さんかく座周辺も同様の活動であった。 </UL> <H5>●9月18/19日</H5> <UL> 夕方から急速に天候が回復し、北天に雲が浮いているもののまずまずのコンディション。うお・９月ペルセウス群が若干出現しているのが見られたが、まだ北東天低いぎょしゃ座β群は見られなかった。 </UL> <H5>●9月21/22日</H5> <UL> 南西低空にある月の影響はなく、透明度のよい空が広がった。ペガスス・アンドロメダ境界付近で群活動を感じるが輻射点としてはまとまらなかった。 </UL> <H5>●9月25/26日</H5> <UL> 日中は小雨模様だったが、夕方から雲が切れ始める。しかしつかの間の晴れ間だったようで、観測開始４５分で霧に覆われて観測不能に。流星活動については特に異常なし。 </UL> <H5>●9月30/1日</H5> <UL> 久々に透明度のよい快晴となり、天頂よりやや西に月があったがさほど影響は感じなかった。流星活動では、ろくぶんぎ群らしき流星が３個あったが輻射点としてはまとまらなかった。 </UL> <DIV align="right" class="author">〔東の観測装置〕</DIV> <HR size="1"> <DIV align="right" class="jump">| <A
