Comet ISON on Final Approach With Sun

The Solar and Heliospheric Observatory (SOHO) captures time-lapse video of Comet ISON approaching the sun.  In less than 2 days the comet will pass by at a distance less than one solar diameter.  It'll heat up to 5000 degrees, and if it survives, depart at a speed of 828,000 miles per hour. 
"Remember: Comet ISON is a dynamically new sungrazing comet, fresh in from the Oort Cloud, and the last time we saw an object like this was never!   Furthermore, a sungrazing comet just three days from perihelion has never been studied in this kind of detail – we're breaking new ground here! When we factor in your standard "comets are unpredictable" disclaimer, what we have is a huge recipe for the unknown."
