"Comet ISON dies...again. Comet ISON is fading fast as it recedes from 
the sun. Whatever piece of the comet briefly survived its Thanksgiving 
Day brush with solar fire is now dissipating in a cloud of dust. Click 
to view a 3-day movie centered on perihelion (closest approach to the 
sun):

"This development makes it unlikely that Comet ISON will put on a good 
show after it exits the glare of the sun in early December. 
Experienced astrophotographers might be able to capture the comet's 
fading "ghost" in the pre-dawn sky, but a naked-eye spectacle is out 
of the question.
"On Nov. 29th, pilot Brian Whittaker tried to catch a first glimpse of 
Comet ISON from Earth, post-perihelion, from a plane flying 36,000 
feet over the Arctic Circle in northern Canada. No luck:

"Ideal viewing conditions from the Arctic revealed no Comet ISON," 
reports Whittaker. "This negative report is to quench the thirst of 
other fellow dreamers under cloudy skies or further south. Later I 
could see that SOHO showed the comet dimming further."

"Despite Whittaker's negative result, it is too soon to rule out 
observations from Earth as the twice-dead comet moves away from the 
glare of the sun. Meanwhile, NASA's fleet of solar observatory will be 
tracking the remains. Stay tuned for more images.
