I regret to report Comet ISON has expired :( Following cremation, the mortal remains were shipped to Oort's Cloud for burial. You can see the nucleus demise around 1800 UTC : http://herrero-victor.blogspot.com/2013/11/comet-ison-c2012-s1.html May It Rest in Peace Regards Dr. Eng. Victor Herrero-Arrieta Ph.D. M.S. Ing.Ind.
