Naked-Eye Comet Pan-STARRS Climbing into Northern Skies | Observations, Scientific American Blog Network:
"This year is shaping up to be a great one for amateur sky-watchers. Toward the end of 2013, astronomers expect the recently discovered Comet ISON (officially designated C/2012 S1) to shine mightily as it approaches the sun—possibly glowing as bright as the full moon. (Comets are unpredictable beasts, though, and often fail to meet the most optimistic predictions for their visibility.)"
