Today the comet ISON was moving towards it's closest distance to the sun, perihelion. Less then 5MM km from the sun and with a speed of more than 300km/s the comet should pass by and show up as the spectacle of the year. Listening live to NASA hangout and looking at SOHO and SDO pictures it's probably clear the comet evaporated. So no ISON but rather ISOF. It was a nice learning the past months and for that see also my tweets with nice linkages on pictures and websites.
