ISON

ISON is not looking good. Recent images taken with the SOHO LASCO C2 imager show the coma smearing out with no bright central condensation. ISON has been a comet of many surprises and its death has been reported (incorrectly) many times. But now it is showing the classic appearance of a comet that has completely disrupted. We’ll have a better idea by the end of the day.
