◎C/2000 A1の軌道と予報位置です
昨年2001年３月20日の佐治の織部隆明氏の観測以来，10カ月ぶりに久万の
中村彰正によって観測されました．氏の CCD全光度は，18.8等でした．なお，
この彗星は，近日点距離が最大の彗星で今後，数年は観測できるはずですが，
おそらく，ほとんどの観測者は，彗星の存在そのものをスッカリと忘れてい
るのでしょう．

◎C/2000 A1の軌道と予報位置です
2000年５月１日の久万の中村彰正氏の観測で止まっていたこの彗星が
11月６日にダイニックの杉江淳氏，28日に中村氏によって，再び，捕ら
えられました．両氏の CCD全光度は，それぞれ，18.4等と18.7等でした．
近日点距離最大の彗星です．接触軌道の離心率は，かなり大きな双曲線
を示しますが，(1/a)org.= +0.000029，(1/a)fut.= +0.000063，L= 7と
原初軌道の(1/a)は，プラスとなります．
