into the sun on the Dec 15th images. Try the animation feature.  
Clear skies,

If it hasn't yet been torn up, we may be able to watch this one enter the SOHO 
LASCO C3 frame ( http://sohowww.nascom.nasa.gov/data/realtime/c3/512/ ). This 
YouTube video shows its path through the frame. It enters from the south on the 
13th, and makes a right turn a couple days later when it makes closest approach.
