◎141P/Machholz 2の軌道と予報位置です
上尾の門田健一氏は，３月16日夕刻，山本速報 No.2462に予報が出ているこの
周期彗星のＡ核の観測に成功しました．氏によると，彗星は，集光した拡散像で
コマの視直径は1'，尾は見られなかったとのことです．氏の CCD全光度は13.1等
でした．彗星は，Ａ核の予報位置から 約30'のずれがあって，その近日点通過時
刻への補正値は儺=+0.487日でした．Ｄ核が生存しているとすれば，山本速報に
ある儺よりさらに，この分の量のずれがあることになります．
下の軌道は，1994年10月以後の観測と門田氏までの観測を連結したものです．
なお，1994年の分裂による非重力効果がすでになくなっているならば，1999年以
後の観測を重力のみで結んだ方が良いかも知れません．
なお，HAL No.197によると，大分の柏木周二氏が３月８日にこの彗星を捕らえ
ているとのことですが，位置的な確認はできていません．
