来自西安工业大学的刘亮同学于北京时间2012年7月15日11时13分在SOHO(Solar & Heliospheric Observatory,太阳和太阳风层探测器)LASCO设备所拍摄的C2图片中发现一颗较暗的迈耶族彗星!成为中国第二十位成功发现SOHO彗星的天文爱好者!这也是世界第三位首颗彗星以非克族开局的发现者!随后Prafull Sharma也在相同时间的图片上发现了一颗亮度更暗的迈耶族彗星!这也是Prafull Sharma的首颗发现!初步判断这两颗彗星很有可能都是96P/Machholz彗星的碎片!能与96P/Machholz彗星同辉实在是让人羡慕!
目前已得到专家认可,目前正在等待彗星临时编号~
以下是彗星报告:

Dear All,
It looks very much to me like the two recent C2 non-group comets are absolutely
fragments of 96P/Machholz! In some ways I am amazed, but in others perhaps not.
You may have seen the new article I posted to the Sungrazer site last week (see link
on the home page) discussing the very complex "Machholz family". The only way this
group could get so large and so varied is by it having a habit of losing chunks of itself.
So, while I am truly surprised that we are seeing fragments of Machholz, it is also *not*
surprising given that this comet (or this "family", I should say) has a tendency to do
just that.
What is also very interesting to me is that this fragmentation event must have occurred
at the previous perihelion passage, given the separation that they all have.
For those of you wondering, these objects will be given "SOHO" designations, and the
credit for detections will be given to Liang Liu and Prafull Sharma. Many
congratulations to both!
Regards,
Karl
PS: I suppose there is still a chance that these are unrelated non-group objects, and not
fragments of 96P... but I really don't imagine that to be the case.
