It looks as if some part of Comet ISON has emerged from its close encounter with the sun. However, it now looks to be a headless comet. The nucleus of the comet has evaporated and the only thing remaining is the coma and dust tail. It's still possible that ISON will be visible in the evening sky over the next several weeks, but disappointingly it will not be the Comet of the Century we had all hoped for. It will most likely only be visible through telescopes. But that will remain to be seen. In the image to the left, Comet ISON can be seen emerging from perihelion at the top left. The remains of its tail can be seen at the bottom right prior to perihelion. This image is from the LASCO C2 Solar Observatory. -Scott Griswold

Check out these images from NASA's various solar observatories.
http://stereo-ssc.nascom.nasa.gov/beacon/beacon_secchi.shtml STEREO Behind shows it best. In particular this sequence. http://stereo-ssc.nascom.nasa.gov/browse/2013/11/27/behind/cor2/512/thumbnail.shtml Looks like a coronal mass ejection is headed right for ISON (Comet ISON in the lower left of the image).. Of course it could be headed in front or behind but will be interested to see what affect it has. Latest word is that ISON could be in trouble and may be breaking up. http://www.isoncampaign.org/Present Will be interesting to watch as it gets closer over the next 24 to 48 hours and reaches perihelion on Thanksgiving Day, if it makes it that far. Let's hope it emerges from its close brush with death and emerges in all its splendid glory. Scott Griswold Hello Horizons Supporters! A clear moonless sky is forecast for tomorrow night - Sunday, November 3rd - so the Horizons Observatory will be open to the public for stargazing from 5:30-6:30 pm. If the forecast holds and it is clear, it will also be very cold (below 20 degrees). Please dress VERY warmly! Please note that the large telescope in the dome will open to the public from 5:30-6:15. At 6:15, the large scope will be used by The Pomfret School sixth grade students to photograph the Great Andromeda Galaxy, so it will not be available for public viewing. The event will be canceled in the event of cloudy skies. Rob Hanson Scott Holson |
