Hello all:
Calculated the photometricals parameters 2004 Q2 MACHHOLZ , curve reduced light
of the comet ( 130 visuals observations ) , and for the 10 of January I obtain a
maximum visual magnitude of +3.4.
obtained photometrical equation : m1=4.6+5*log(del)+2.5*4.8*log(R)
m0=4.6 n=4.8
m1(10-01-2005)= + 3.4

(注：亮度预报是老的，实际亮度要高0.5等左右） 好啊!看来Q2离我们越来越近了!兄弟们赶快做好准备啊!最佳观测时间应该是1.10日左右,希望到时候有好天气! 高半等啊！那极大3.5等了？好家伙！ 那个经天图有没有近期的？ 美国航天局最新的天文报告说，从现在起直至明年1月上旬，生活在北半球的人们甚至不需要借助望远镜，也能够看见在今年8月新发现的一颗较明亮的彗星。它现在所处的位置距北半球东南方向的地平线很近。然后每天它在天空中越升越高。
这颗彗星是由道格拉斯·马可霍尔兹第一个发现的，所以用他的名字命名，而科学家给它起的“学名”是c/204Q2.它是一颗由岩石和冰组成的天体，在太阳的作用下，升华的水汽等被推到背向太阳的一侧，形成彗尾。明年1月5日和6日，这颗彗星距地球最近，只有3200万英里。
现在，还只是很有经验的人能在无月而且黑暗的天空背景下用肉眼观测到它，而到12月11日以后，在新月较小，或月亮距彗星较远的晴天夜晚，将是观察的较好时机。在黑暗的旷野处，一般天文爱好者也可以看到它。 我们这里好像已经有人观测到了！
现在知道没有望远镜的难处了！

参考一下吧 :) ^^ 希望大家都观测下。 我昨晚上在阳台上用双筒看到了。 :twisted: :twisted: :twisted: 我昨晚上在阳台上用双筒看到了。 :twisted: :twisted: :twisted:您住在哪里？ 国外9－10号的观测

百武彗星当年有1等那么亮，当时在我家阳台上都肉眼可见，这次的Q2最多才3等多。。 看到。
真不错。 最近天气不错，就是忙着考试。估计怎么也得1月底才能观测上
