The annual Perseid meteor shower is lighting up the night sky. Intermittently.
The Earth just now is venturing into the debris field from Comet Swift-Tuttle, so skywatchers likely would see only a few Perseids an hour now.
But on Aug. 12, the planet will plow into the thickest part of the debris, when stargazers could see dozens of meteors an hour.
According to the NASA news service Science@NASA, the best time to watch is after dark on Aug. 11 and before sunrise on Aug. 12. The glare of a gibbous moon may impede some meteor viewing. But NASA says from around 9 to 11 p.m. on Aug. 11, the moon will be lower in the sky, lessening the glare.
Never miss a local story.
The meteors are called Perseids because they appear to originate in the constellation Perseus.
