Hi All,
Comet ISON has been closely monitored at the IRAM millimeter telescope in
Spain by Israel Hermelo (IRAM Granada) and myself (Caltech/NRAO) for the
last 6 days. We observe consistent, rapid fading of the molecular emission
lines between Nov. 21 and Nov. 25 by at least a factor of 20 (likely
more). This may indicate that the nucleus is now at best marginally active
or that... it no longer exists.
Regards,
Michal
大意是IRAM毫米望远镜观测到观察到分子发射迅速衰落,可能说明彗核核活动微弱或者说...它不再存在。
