Current comet magnitudes (February 4) and observable region (February 1)
===========================

LINEAR (2011 F1) 10 ? steady Poor elongation 2012 November
246P/NEAT 10 steady ? 15 N to 35 S early morning 2013 January
Bressi (2012 T5) 10.5 bright 30 N to 60 S evening 2013 February
LINEAR (2012 K5) 11 fade 55 N to 60 S evening 2013 January
LINEAR (2012 L2) 11.5 bright 90 N to 10 S best evening 2013 January
McNaught (2011 R1) 12 steady 30 N to 55 S morning 2013 February
262P/McNaught-Russell 12 fade 50 N to 45 S evening 2013 January
LINEAR (2012 A2) 12 fade 90 N to5 N best evening 2012 November
29P/Schwassmann-Wachmann 13 ? varies 35 N to 60 S morning 2013 January
Garradd (2009 P1) 13 ? fade 50 N to 60 S best midnight 2012 November
168P/Hergenrother 13 fade 90 N to 10 S best evening 2012 December
LINEAR (2010 S1) 13.5 fade 90 N to 65 N early eve/morning 2012 November
Catalina (2012 J1) 13.5 fade 75 N to 15 S evening 2012 December
ISON (2012 S1) 14.5 bright 90 N to 25 S best evening 2013 January
The observable region is an approximate indication of the latitude at which the comet may be seen. Under good conditions comets may be visible outside this range. The period when visible is for the UK if the comet is visible from the UK, otherwise for 40 S or the Equator as appropriate.The last visual observation is as received by the Section.Beginners will often find comets fainter than about 7th magnitude difficult to locate - see below for information on positions and finder charts.

这还不好办！……只要，到时候，不出意外。
怎么说？那得有器材啊。当然，彗星本身不出以外最关键。毕竟还有哈雷撑腰~
记得我小时候站在楼顶上看1985年的哈雷彗星来着，可惜天气不好没看到，太遗憾了！
还能怎么观测，都是掠日彗星，只能在晨昏之际观测。

三楼，此位不用占了……因为：1997年的海尔-波普——我没看到。
海尔-波普看了，当时还不到10岁。每天傍晚西边天空，很壮观，连着看了几周！

彗星是有彗尾的。
今年一定看，用双筒！

呵呵！……那就只能再慢慢等到它下次回归时——2061年，再看了。
嘿嘿！……但愿我们大家都能活到那个时候。{:soso_e113:}

呵呵！……这就是你不知道了——
其实，我们还可以随时从SOHO卫星的C3和C2，以及SWAN图片上看到这些掠日彗星在太阳附近的一举一动。

帖子的主要内容到哪儿去了？ 1995年的百武彗星观测记，前几楼还都空着呢
进来学习呵呵

唉，海尔来的时候我才10天大，只能期待ison够给力了
才16岁。我那时都初中了啊
百武和海尔-波普彗星都看到过，不过没有看到池谷-张彗星。
海尔波普的那次很强大!记得好像夏天快入秋了。能持续了快一个月吧，每天晚上都挂在西偏北大约70度高的方位上。非常明显，并且彗尾很长。那次基本是肉眼可以看到的最好机会了。不知道哈雷是啥样。
哎！……:$目前，可以说比较遗憾吧！
由于，本地的天气一直不给力；:'(
我到现在还没看到这颗（C/2011 L4）彗星啊！
只看过海尔波普，那个叫壮观。
期待像百武，海尔-波普那样的彗星。
