This
annual shower has it all! It offers a consistently high rate of meteors year
after year as it produces a higher percentage of bright ones than most other
showers. It occurs in August when the earth’s orbit passes thru the debris left
behind from Comet Swift-Tuttle. Many people take summer vacation now and the
weather has favorable night time temperatures.
The shower not only
produces lots of “shooting stars”, up to 100 per hour at the peak under optimal
circumstances, but it does so this year with the Moon out of the sky. The best
views will come in the predawn hours of Thursday morning when the shower’s
radiant climbs the highest. It is more typical to see a meteor every couple of
minutes or 25-30 shooting stars per hour. That may include some particularly
bright ones known as Fireballs that the Perseids are known for. Well worth the
wait!
You want to take in as
much sky as possible. And best of all, you can observe the spectacle while
lying down in a rural area away from town or city light pollution. The darker
the sky, the more you will see. Who could ask for more?
Just look. No binoculars or telescope. Try leaving the shutter open on your camera with a wide angle lens mounted on a tripod with a cable or electronic shutter release. Exposure for a few minutes at a time and you may catch several in a single exposure.

The meteor shower is expected to peak
at 4 a.m. on Aug. 13, although there should be an above average number of them
right thru to August 20th or so. That's because the meteor shower is
caused by the Earth passing through a trail of dust and debris left behind by
the Comet Swift-Tuttle, which can be thicker in some places than others. Whether
it's the peak night or not, you'll see more meteors in the early morning than
the late evening. Here’s why! The geometry of the earth and the debris itself
means you'll see more meteors, just as when you drive in a blizzard, you’ll see
more snow hitting the front windshield of the car than the back window. Later
in the night, the part of the sky where the meteors originate will also be
higher overhead, giving you a better view.
Look
toward Perseus and Casseiopeia
The meteors will streak across the sky
at about 60 kilometres per second from near the constellation Perseus that the
meteor shower is named for. For the best views of this shower, look about two-thirds of the
way up from the horizon toward the northeast. Don't get tunnel vision staring
at one location. Let your eyes wander so your peripheral vision can pick up
faint or bright meteors that you otherwise might not see. Enjoy!
