Moonlight (and possibly clouds) will interfere with early morning viewing of the 2009 Perseid meteor shower.

The annual Perseid meteor shower peaks this Wednesday (August 12).

Last year I recommended going out to view the Perseids at the ridiculous hour of 4 a.m. I vividly remember both the many meteors I saw between 4 and 5 a.m., as well as the effort involved in staying awake at work in the hours that followed.

This year, you and I can justify not trying so hard for two reasons:

(1) The weather. The forecast doesn’t look terribly clear for the Triangle.

(2) The Moon. After about 11 p.m., moonlight will wash out the dimmer meteors from view. The almost last quarter Moon rises within a few hours after sunset and stays up the rest of the night.

Meteors are also known as “shooting stars,” but they’re not related to stars. Meteors are caused when Earth travels through space debris (that left by Comet Swift-Tuttle in the case of the Perseids). When the debris interacts with the Earth’s atmosphere, a flash of light is created.

Perseid meteors appear to radiate away from the constellation Perseus, but you don’t need to know how to find Perseus to see the meteors. Take a lawn chair or sleeping bag to a spot away from city lights, and look about halfway up the sky. Choose a direction that’s dark.

If skies are clear, the best times to look for Perseid meteors include Tuesday evening to Wednesday before dawn, and Wednesday evening to Thursday before dawn. The most activity will be between midnight and dawn. If you’re watching after the Moon has risen, look away from it to a darker part of the sky. After giving your eyes 15 minutes or more to adjust to the darkness, you may see a Perseid meteor every few minutes.

If the weather permits, Morehead will hold a special Perseids skywatching session from 9 to 11 p.m. this Wednesday, Aug. 12, at Jordan Lake (Ebenezer Church Recreation Area).
