The annual Perseid Meteor Shower peaks August 11-13 and is the closest thing to a sure thing in when you’re talking meteor showers. The Perseids kick out 10+ meteors per hour at peak, and the darker your setting, the more you will see. EarthSky has detailed tips & diagrams about this summer favorite in Everything you need to know: Perseid meteor shower:
Start watching in the second week of August, when the Delta Aquarid meteor shower is rambling along steadily, reliably producing meteors each night. Then keep watching in the second week of August, when the Perseids are rising to a peak. The Perseid shower is known to rise gradually to a peak, then fall off rapidly afterwards. In early August (and even through the peak nights), you’ll see them combine with meteors from the Delta Aquarid shower. Overall, the meteors will be increasing in number from early August onward, and better yet, the moonlight will diminish until the new moon on August 14, 2015.
Don’t rule out early evenings. As a general rule, the Perseid meteors tend to be few and far between at nightfall and early evening. Yet, if fortune smiles upon you, you could catch an earthgrazer – a looooong, slow, colorful meteor traveling horizontally across the evening sky. Earthgrazer meteors are rare but most exciting and memorable, if you happen to spot one. Perseid earthgrazers can only appear at early to mid-evening, when the radiant point of the shower is close to the horizon.
As evening deepens into late night, and the meteor shower radiant climbs higher in the sky, more and more Perseid meteors streak the nighttime. The meteors don’t really start to pick up steam until after midnight, and usually don’t bombard the sky most abundantly until the wee hours before dawn. You may see 50 or so meteors per hour in a dark sky.
An open sky is essential because these meteors fly across the sky in many different directions and in front of numerous constellations. If you trace the paths of the Perseid meteors backward, you’d find they come from a point in front of the constellation Perseus. But once again, you don’t need to know Perseus or any other constellation to watch this or any meteor shower.
