The Perseids will peak again Tuesday with mostly clear skies on tap. But will haze and a somewhat full moon play spoiler?

Skywatchers are in for a rare treat tonight, as the Perseid meteor shower coincides with a potential display of the Northern Lights

The Perseids are known for being especially swift and bright, and in a good year viewers can expect to spot between 50 and 100 meteors in an hour. This year, with moonlight hampering dark skies, fewer than half the usual number of meteors could be visible. Still, 25 shooting stars an hour is worth waking up early for.
