Just yesterday Comet LINEAR (C/2001 A2) was fading from view as it receded from Earth. But now the volatile comet is again a naked-eye object. It's glowing at about 4th magnitude in the pre-dawn sky with a pair of tails you see through binoculars or a modest telescope. Comet LINEAR has a history of crumbling then flaring as freshly exposed ice is vaporized by sunlight. What will the comet do in the days ahead? See for yourself! Visit SpaceWeather.com for details.
