Got some spare time tonight? From about 9 or 10pm in your local timezone, peaking just before dawn, the Great Perseid meteor shower will be going on. I witnessed this a few years back and it was spectacular — maybe 50-100 meteors an hour.
As the night unfolds, Perseus climbs higher and the meteor rate will increase many-fold. “By 2 am on Monday morning, August 13th, dozens of Perseids may be flitting across the sky every hour.” The crescendo comes before dawn when rates could exceed a meteor a minute.
