Everything you need to know: Perseid meteor shower | Astronomy Essentials | EarthSky

Everything you need to know: Perseid meteor shower | Astronomy Essentials | EarthSky: "Everything you need to know: Perseid meteor shower"

No matter where you live worldwide, the 2014 Perseid meteor shower will probably peak on the mornings of August 11, 12 and 13. On a dark, moonless night, you can often see 50 or more meteors per hour from northerly latitudes, and from southerly latitudes in the Southern Hemisphere, perhaps about one-third that many meteors. Unfortunately, in 2014, full moon comes on August 10. And not just any full moon, but the closest supermoon of this year. Thus, on the Perseids’ peak mornings, a big and bright waning gibbous moon will obscure all but the brightest meteors. But all is not lost! It just means you need to start observing before the shower’s peak this year.
