Comet ISON has been closely monitored at the IRAM millimeter telescope inSpain by Israel Hermelo (IRAM Granada) and myself (Caltech/NRAO) for thelast 6 days. We observe consistent, rapid fading of the molecular emissionlines between Nov. 21 and Nov. 25 by at least a factor of 20 (likelymore). This may indicate that the nucleus is now at best marginally activeor it no longer exists.
