前几天查了一下星图，最亮时也就不到-5等吧，也就是说当初亮度高估了。
那个预报是以天为单位，而不是小时，分钟，秒，所以最亮亮度仍然可能超过-5

是真的，如果彗星中途不瓦解，明年就有大戏看了
ISON彗星瓦解的可能性很大。
但愿彗星能结实点。。。
但愿天气好一点
现在到哪里了，亮度超过98年的海尔波普有戏么？
现在有没有最新的情报？数据繁杂看得眼花缭乱

这些数据哪里来的？靠得住吗？
这段文字来自NASA网站11日的新闻，提到8日的图片，亮度1.5--1度。
Comet ISON shines in this five-minute exposure taken at NASA's Marshall Space Flight Center on Nov. 8 at 5:40 a.m. EST. The image has a field of view of roughly 1.5 degrees by 1 degree and was captured using a color CCD camera attached to a 14" telescope located at Marshall. At the time of this picture, Comet ISON was 97 million miles from Earth, heading toward a close encounter with the sun on Nov. 28. Located in the constellation of Virgo, it is now visible in a good pair of binoculars.
呵呵，这些数据来自IAU ：http://scully.cfa.harvard.edu/cgi-bin/returnprepeph.cgi?d=c&o=CK12S010
