艾森彗星：某彗星族的成员？Sep 28th

http://y234.cn/wp-content/uploads/2012/09/comet-of-1680-600x607.jpg 1680年大彗星的版画，来自The Settlement of Germantown, p.126
刚刚宣布发现的艾森彗星ISON)]惊喜不断：著名业余天文学家J. Bortle（就是提夜空分类法的那位）指出，艾森彗星和1680年大彗星的轨道惊人地相似，暗示两者之间可能有同一起源（原帖）。著名彗星猎手M. Meyer（梅耶彗星族的发现者）进一步指出C/2007 C7 (SOHO)也和两者有相近的轨道（原帖）。近日距如此小的天体有如此相近的轨道，纯属巧合的概率并不大。另外，艾森彗星的轨道距离地球最近只有0.02天文单位。如果它和1680年大彗星的确来源于较早碎裂的母彗星，那不能排除其轨道上有流星体存在且已经有所扩散。这一可能的流星群活动时段是12月28日前后，辐射点位于巨蟹座附近。 1680年大彗星被认为是人类首颗用望远镜发现的彗星，发现者是德国天文学家Gottfried Kirch。但这颗彗星有时也被称为“牛顿彗星”，因为牛顿利用这颗彗星来验证了开普勒行星定律的正确性。

值得期待！

有可能2012S1的近日距还不够精确，如果近日距更小，可能会有更惊讶的表现。
ISON彗星有可能带来新的流星雨吗？
Sorry for the bad English
The orbital elements of this new comet can to do a meteor shower,
this it's not sure, too for non definitive orbital data,
the actual data give the following meteor shower:
maximum 15,9 January (solar longitude 295?
geocentric speed 50,9 km/s
radiant around 152,4? +16,4?(10 H 10 M, + 16,4?, very near to the star
Eta Leonis.
The radiant should be very well visible from Northern emisphere from 22.00
local time for 45?North
Naturally each future change in orbital elements shall change
the data of the shower as too its existence or not.
Best greetings.
Roberto Gorelli
期待。九七那次的彗星没看到，挺遗憾的。

C/2012 S1这个彗星的轨道平面与黄道交角很大，而且是黄道穿越型的彗星，
所以低纬度地区应该是最佳观测区 ...
哦，悲剧了，我北纬23°啊！
104日照片，彗星发育良好::070821_18.jpg::
希望撞到金星上
看来今年只是虚岁2011，明年才是2012，HUMAN系时作未日准备了
哥看这不是彗星，而是“上帝归来”

瓦解的话，就是狮子座级的暴雨了吧
错，不幸运的话应该就是地球未日
发现C/2012 S1 ISON的大佬和设备，这个要留存::070821_18.jpg::

73和74楼是从2012吧串过来的吗？回去吧，天文论坛不适合你。
