发几封与A1无关的，大家见谅，我想或许有同好需要。

是呀！不知是他们没去观测还是观测了把消息独吞了。观测了的应该分享分享嘛！

才在一家国外网站看到，今年的第一个慧星的报导，据此报导称到3月7日这颗慧星就要离开地球，不知道是真的假的。 : 不过现在C/2006 A1到什么星座或位置了呀？哪位同好知晓？

2006 Feb. 28.79  UT m1=5.4 Dia=3'  DC=7? 8x56 binocs
Kearn Jones, Adelaide, Australia

observed from outer suburban backyard ducking under the throw of
streetlights, below fence line, in clear conditions.
Clearly see .45 d of tail easily all the time in 8x56's - sometimes
glimpsed around a 3 or so degree tail with them.
In 20x80's very impressive little comet - tail filled 3d fov most of
the time and comet and tail looked 'great' ;)
mag. 5.21 Tau Capricorni comparison star visible ne below comet in
vicinity. A1 at nearly 10d altitude at the time.

C/2006 A1 Pojmanski: 2006 Feb. 28.51 UT: m1=5.4, Dia.= 3' 7x50B
Binoculars. No tail visible. Limit magnitude 3.5 in metropolitan area
of Mexico City.

Hi All!

I observed C/2006A1 in FEB 27.32UT from a rural zone
in Mairipora. The sky had a excellent transparency and
a naked eye limit around 6.0-6.5.
I observed 1 deg of tail and a beautiful bluish coma,
using 11x80 binoculars.
The comet was also observed with naked eye.
Following, my report...
