Heads up! The Perseid meteor shower is peaking.

If you see a shooting star on Friday the 13th, does the day cancel out the wish?

Superstitions aside, the bigger complication for wishing upon stars may be cloudy skies as the Perseid meteor shower reaches its peak.

The Perseid showers are among the strongest meteor showers of the year in the Northern Hemisphere and among the easiest for families to view. The celestial show starts in late July when kids are out of school and family schedules can better accommodate late night or early morning viewing. This year's Perseid activity should continue through Aug. 18, according to space.com, with peak nights Aug. 11-13.

Longtime skywatcher Bill Haley said it might be best to temper expectations as the "wildly optimistic predictions of 50 to 100 meteors per hour that you see on the internet" have not happened while he's been watching.
