1980年代,写真捜索で新彗星を発見しようと,暇さえあれば夜空の写真を撮りました.しかしちっとも成果はあがりません.1個の暗い彗星を写野にとらえたチャンスはあったのですが,自分のものとして拾い上げるに至りませんでした
山のような捜天ネガを積み上げるのに少々むなしさも感じ始め,多少なりともその中からデータを残したいもの,と考えて「観測」を始めるようになったわけです.新天体の捜索とあわせて,彗星や小惑星の精測位置観測,発見直後の確認観測を本格的におこなうことにしました.特に彗星の確認観測は自宅に観測所がある利点を充分に活かせ,良い経験を積むことができました
本格的に観測報告をするようになってからの,彗星の精測観測数を示します.
