◎C/2001 Q2の軌道と予報位置です
台風11号が去ったあと，美星で22日早朝に，ほぼ，曇天の状況で観測に
成功しました．なお，前々回のEMESで記したとおり，この彗星の軌道は，
下のように103P/Hartley 2の軌道と良く似ています．
位置予報は， 2nd Orbit（楕円軌道）からのものです．もう少し，長半
径が大きいことを期待したいものです．

◎C/2001 Q2の概略軌道と予報位置です
上尾の門田健一氏は，21日早朝に，この彗星の観測に成功しました．
氏の CCD全光度は，12.4等，彗星は，中央集光をもつ拡散状で，コマ
の視直径は，1'.2，P.A. 275度の方向に１'の淡い尾があるとのことで
す．なお，軌道決定された軌道（T= 2001 Aug. 28, q=0.98 AU, W=175,
N=218, I=14)は，103P/Hartley 2のそれらに良く似ています．
