12等變到9等

Resulting magnitude is 8.7 mag in V-band with 3.15' coma. Apparently
much brighter then previous visual estimates.

WIKI
http://en.wikipedia.org/wiki/15P/Finlay

這顆彗星的亮度在1926年之後開始下降,因此失蹤了一段時間,直到1953年才再度觀測到每一次的回歸
2014/12/27 是近日點 , 不過也是  0.97 AU 應該不會太亮.

看星圖是月底會最亮
不過在火星旁邊
要拍到可能是非常難

接下來角度會比較好拍
不過亮度會減低
大概是沒什麼看頭了

又再變亮了一次阿


不過還是很暗吧

Comet 15P Finlay appears to be in outburst, and has been reported to be around magnitude 9, 2.5 mgnitudes brighter than predicted.

Unfortunately, at astronomical twilight the comet s only 13 dgerees above the hroizon from SSO, lower from the northern scopes.
