天文ガイド：彗星のページ全天図の彗星（m1<19.5 or m2<19.5） 全天図の彗星の経路は毎月１日から翌月１日まで（彗星の経路図とは異なることに注意）． 全天図に描く彗星があまりにも多いので，全光度で19.5等，あるいは，核光度で 19.5等より暗い彗星は描かれていない．この処置によって，最近，発見されてい る19等級より暗い多数の新彗星が描かれていないこともあることに十分注意のこ と．なお，観測用の軌道要素は，今月21.5等より明るく見える彗星まで含まれて いる． No. 彗星名 赤経 赤緯 光度 最終観測 天文台 h m ｡ , m1 m2 年 月 日 CDE 1 95P=(2060) ｶｲﾛﾝ 23 58.2 +03 33 . 18.7 2018 01 12 (Q11) 2 C/2006 S3 (LONEOS) 09 35.6 +00 33 18.2 19.9 2018
