From NASA & JPL website:
According to NASA meteor expert Bill Cooke, the Perseids are perhaps the most popular meteor shower of the year. They will be in "outburst" in 2016, which means they'll appear at double the usual rates.
"This year, instead of seeing about 80 Perseids per hour, the rate could top 150 and even approach 200 meteors per hour," Cooke said. It's the first such outburst since 2009.
Earth will pass through the path of Comet Swift-Tuttle from July 17 to Aug. 24, with the shower's peak — when Earth passes through the densest, dustiest area — occurring on Aug. 12. That means you'll see the most meteors in the shortest amount of time near that peak, but you can still catch some action from the famed meteor shower before or after that point.....
