Comet Gerradd
7.5 magnitude comet in Sagitta
Uploaded
9/1/11
There
are few clear nights during the monsoon season, and this one
came during the brightness peak of this long period comet now
in Sagitta in the evening sky and near the zenith. The comet
visually is a bust, very d little tail can be seen amongst a
rich star field, with the coma only a dim glow with a fan shaped
tail. This was a deep 85 minute exposure with the 12.5"
on a damp night at around 9pm. The head has at least a strong
green coloration from CN, but the nucleus was nothing more than
a dim central condensation. |
