lz资料收集真全，谢谢分享
楼主辛苦了，那颗彗星现在很暗了，C2C3有又不更新照片。
今天凌晨已经过近日点了吧，还在等，晚上会不会有更新呢？
COMET LOVEJOY SURVIVES: Incredibly, sungrazing Comet Lovejoy appears to have survived its close encounter with the sun. Lovejoy flew only 140,000 km over the stellar surface during the early hours of Dec. 16th. NASA's Solar Dynamics Observatory caught the comet emerging from perihelion (closest approach).

Movie formats: 25 MB Quicktime, 800 kB m4vComet Lovejoy began the week as a chunk of dusty, rocky ice some 200 meters in diameter. No one can say how much of the comet's core remains intact or how long it will hang together after the searing heat of perihelion. Another movie from SDO hints at the rough treatment this comet has endured.Stay tuned for more movies!

Lovejoy 彗星高速衝過近日點時，雖然被太陽的高溫蒸發大部份物質，但仍然能夠成功逃離太陽，避免完全消失

因受太陽蒸發彗星物質，掠日後 Lovejoy 彗星光度應該較原來預測暗，實際情況要觀測核實。
lz辛苦了！
真诚的谢谢！

啥时候能出现个肉眼可见的彗星
2013年泛星彗星亮度达0.72等 (目前数据）

This one is a short animation of four frames from the STEREO-B EUVI instrument at the 171-angstrom wavelength (corresponding to about 1.5million degrees, I believe). The comet is clearly visible racing away from the Sun, leaving a wiggly-tail in its wake! Why the wiggles? We're not sure -- we need to start studying that when we get all of the spacecraft data from STEREO-B this weekend. However, we think there may some kind of helical motion going on, or perhaps there's a projection affect and we're seeing tail material magnetically "clinging" to coronal loops and moving with them. There are other possibilities too, though, and we will certainly investigate those! We should have equivalent images from the STEREO-A spacecraft which we will also get this weekend. When we pair these together, and throw in the SDO images too, we should be able to get an incredibly unique 3-D picture of how this comet is reacting the the intense coronal heat and magnetic loops. We really are going to learn a lot here.
I won't post much here over the weekend (I've already been doing 18-hr days on this) but I will try to get the word out if/when we hear from Hinode. On Monday I will certainly be back with more movies and over-the-weekend updates. I enormously appreciate all the traffic and interest that has been directed at this page and this project. I've tried to keep things fresh and informative, yet informal too. Hope I managed to convey all that (without too many typos, which I do keep finding...)!

彗星由太阳的东南运行到太阳的西北，黄昏时彗星最有可能出现在太阳的右边

啥时候能出现个肉眼可见的彗星
W3 就是肉眼可见。不过一般实在南半球。
目前W3的亮度预测，基本没法用了，世界上彗星界大牛们的预测都全军覆没了。请大家注意最新的实时情况吧，过近日点w3一直在增亮，目前亮度-4等上下。

这些数据仅作参考，要用事实说话。
如果你会看SOHO图的话，可以看看。你就会知道，W3已经完全超出人们的想象了，即便是最新的MPC预报，跟实际情况比起来，也只能算的上是扯淡，更新赶不上变化。
C/2011 W3 不仅成为一个传奇，它也成了一个迷，他的周期，他的大小，近日距，现在都有很大的争论。最让人疑惑的是，过了近日点他竟然在不断的增量，mpc预报显示是不断的减弱，并且已经超过了W3的近日亮度。
所以说你以后转发信息，最好能自己也要考证下，发那么多错误信息，是会误导大众的。
