目前多少星等？

希望可以有C/2014 Q1的表现啊

how about  light curve about this comet ?

打错了 是Q2

from comet-ml

someone said :
Just a follow-up... the orbit for the recent SOHO "non-group" comet - C/2015 D1 (SOHO) - has now been published: http://www.minorplanetcenter.net/mpec/K15/K15D73.html

Ground-based attempts are strongly urged so the orbit can be refined. Keep in mind two different orbit solutions: one pre-perihelion, the other post-perihelion - be sure to use the latter (unless looking for "precovery" images... but does anyone survey that part of the sky?).

For a couple of reasons, we expect this comet to be fading *fast*, and the orbits derived from SOHO are always p

fading *fast*  ??

已经过近日点了，又一颗掠日彗星。

我们有机会拍得到吗?

不易, 2月 21日 亮度是4等,
但是 太阳刚下山下, 如 0~-4等如 金星类够亮才能拍下来吧,

3月时 角度高些 , 但是, 可能亮度掉很快了 .

中间偏右一串烟状的痕迹

地平高度不够

这算是拍到了吧
