Comet ISON is now viewable on SOHO's LASCO C3 camera as it heads towards the Sun. Read more here. Passing within 1.3million kilometers of the Sun's surface, it's top speed will be around 1.3million kph (the numbers are coincidence)! With luck, the SOHO (and other) cameras zoned in on it will show a reappearance early Friday. If not, then we know that ISON has met a fiery end!
ISON, discovered in September 2012, was showing signs of petering out since November 23rd despite a series of outbursts from November 18th brining it up to naked eye visibility. Now we wait to see if it will survive the trip round the Sun (and not into it) and reappear in our skies.
Don't forget Comet 2013 R1 "Lovejoy" is one of the most recent comets currently on view since October. IFAS members share their own observations here.
