四月五号前后从M31旁边近距离划过,跟当年的池谷-张何其相似!而且这颗的亮度更值得期待!下面附上一张北京2013年4月5日晚7点的模拟图,月相很理想,必然会是肉眼和双望奇观!

彗星开始进入凌晨天空,与水星相距2度,观测条件将会逐渐转好。

有没有情况在接近太阳中因为路过的行星原因发生点变跪之类的事呢。。。还想在看一次跟海尔波谱那样的彗星。。。T。T55555

Re: 2011 L4 visual obervations?
Hi everyone,
It appears this comet has brightened some over the past week. After my
unsuccessful attempt a week ago, and after having to wait a few mornings for
the comet to be in a "clean" location during my observing window, I
successfully observed it visually this morning: March 30.44, m1=14.3, 0.6'
coma (41 cm reflector). It's small and quite condensed (DC perhaps around 6
or 7) and despite its faintness is not especially difficult to see.
A lot can happen over the next year, but the fact that it is already
visually detectable would seem to be a good early sign.
Sincerely,
Alan
