Check out these images from NASA's various solar observatories.
STEREO Behind shows it best.
In particular this sequence.
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.
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.
