Terry Lovejoy運氣真好,幾年的努力沒白費,是辛勞換來的,運氣固有,可技術更高!526日他再次發現一可疑彗星,依然是偏綠,新西蘭的John Drummund發現目標彗發直徑約1上下,目前E12已經確認了該目標,亮度在13等上下。仍爲NEO確認頁面的目標,估計明後天就可以正式確認,獲得編號了。祝賀!

這是到目前爲止的資料:

我在SWAN中找到了疑似對應目標,亮度約在1213等,較彌散:

黃道座標(J2000

β = 79.024 deg., δ = -38.04 deg.
β = 81.220 deg., δ = -38.04 deg.
β = 82.317 deg., δ = -38.04 deg.
β = 82.317 deg., δ = -38.04 deg.

赤道座標(J2000):

R.A. = 5.405 h, Decl. = -14.94 deg. J2000.00
R.A. = 5.524 h, Decl. = -14.82 deg. J2000.00
R.A. = 5.583 h, Decl. = -14.77 deg. J2000.00
R.A. = 5.583 h, Decl. = -14.77 deg. J2000.00

  誤差在1平方度上下。

  方向與NEOCP中的有些出入,其值應爲P.A.=0.88,速度也有點問題:NEOCP中值約爲3"/min
