<P>年間の観測夜数は毎年１００夜を目標としている。１年は３６５日であるから３～４日に１日観測すればよい計算だが、天候・月明かりもありなかなか難しい。今年は１０月までは良いペースであったが、１１月が多忙で急ブレーキがかかってしまった。晴天が期待できるこの１２月をハイペースで乗り切らなければならない。寒さとの格闘の日々が続く。</P> <HR size="1"> <H3>■観測結果</H3>

<UL> ２１時２３分ごろにχＯｒｉ群と思われる１等の粒状流星が出現。ふたご群も既に３つと幸先よい出現で、今後の活動が実に楽しみ。 </UL> <H5>●12月5/6日</H5> <UL> ３日に引き続きχＯｒｉ群が印象的で、２１時５７分に２等・５９分に１等とともに粒状流星が出現。ふたご群は全て３等以下だったためχＯｒｉ群の存在感が際立つ。 </UL> <H5>●12月6/7日</H5> <UL> ２２時２３分にマックホルツ彗星（すでに肉眼等級）の淡い光芒を切り裂くように１等のふたご群が出現。χＯｒｉ群は昨日と違い全て４等以下だった。 </UL> <H5>●12月7/8日</H5> <UL> ここ数日と違って明るい流星はなかったが、ふたご群は極大に向けて順調に増加。観測時間帯が早いこともあり、うみへび群らしい流星はなかった。 </UL> <H5>●12月8/9日</H5> <UL> ふたご群は早くもＨＲ＝１０を突破。３等台の流星が中心だが、今後の活動にさらに期待！ </UL> <H5>●12月10/11日</H5> <UL> 夕方は快晴だったが、この時間は薄雲が多く１時間で観測断念。ふたご群の伸びがいまいちだがあまり良くない条件を考えると妥当な数値か？？ </UL> <H5>●12月11/12日</H5> <UL> 昨日と逆に夕方は曇天だったが、２１時すぎから雲が切れる。ふたご群は火球も出現して１０日とは比較にならない華やかさとなった。 </UL> <H5>●12月13/14日</H5> <UL> 夕方から小雨が降り始めた御殿場市内に早々に見切りをつけて山中湖・河口湖周辺を晴れ間を求めて彷徨う。その甲斐あってか断片的ながら５時間程度の観測に成功。雲がなくなり条件の良くなった０３時台は瞬間的に２・３個の出現が珍しくなく、ふたご群の華麗な出現を充分堪能することができた。 </UL> <H5>●12月14/15日</H5> <UL> 昨日から広がった雲が切れず今後の予報も悪いことから半ばあきらめていたが、２１時過ぎから雲がなくなる。ふたご群は数こそ多いが明るいものは少なく昨日の活動と比較してかなり見劣りする。<BR> ２３時以降は再び雲に覆われてそのまま朝まで晴れることはなかった。 </UL> <H5>●12月15/16日</H5> <UL> ようやくキレのよい空が戻ってきたが、時すでに遅し。ふたご群は数こそ多いがマイナス等級がわずか１つで、一昨日の活動がウソのよう。 </UL> <H5>●12月16/17日</H5> <UL> ふたご群は昨日の１／３と順調に減少。風が強く寒さが身にしみる。２１時４５分すぎにふたご座からおひつじ座へ４等の長経路流星が出現した以外は特に目立ったものはなし。 </UL> <H5>●12月20/21日</H5> <UL> ２１時２８分に輻射点のすぐ近くに出現した－２等の群流星をはじめ、こぐま群の明るい流星（他は２等２個）が目立つ。 </UL> <H5>●12月22/23日</H5> <UL> 不測の事態に備え薄明中から待機する。こぐま群は適当な間隔でパラパラと出現するが０等が１個あった以外は２・３等の流星が大半だった。数が増える気配がないのと寒いこと（笑）で２０時に切り上げる。 </UL> <H5>●12月25/26日</H5> <UL> いくら透明度がよくても強烈な月明かりがあってはどうしようもなく、特に異常は見出せなかった。 </UL> <H5>●12月28/29日</H5> <UL> 天候が崩れる前のつかの間の晴れ間。ぎょしゃ座北部で群活動を感じる。 </UL> <H5>●12月29/30日</H5> <UL> 日中は今シーズン初めての積雪となったが夕方から急速に天候が回復。しかし透明度はよいが２５日同様に厳しいほどの月明かり。特に異常なし。 </UL> <H5>●12月30/31日</H5> <UL> 夜半前は朧月夜で観測は半ばあきらめていたが、朝方起きると奇跡の晴天！しぶんぎ・かみのけ群の初期活動が見られた。 </UL> <H5>●12月31/1日</H5> <UL> 日中いっぱい降り続いた雪で、これまで記憶にない白い大晦日。１８ｃｍに達した積雪と冷たい風で凍える年越しとなった。かみのけ・しぶんぎ群が極大にむけて着実に増加中。 </UL> <DIV align="right"
