A HYPERACTIVE COMET APPROACHES EARTH: A small but hyperactive comet
named "46P/Wirtanen" is nearing Earth for one of the 10 closest
approaches by any comet of the Space Age. Wirtanen's emerald green
atmosphere is now larger than the full Moon, and it is an increasingly
easy target for binoculars and small telescopes. Naked-eye viewing
could be just around the corner. Visit Spaceweather.com (http://spaceweather.com) for the full story.
