A Great Year for the Perseids
This famous shower, rich in bright meteors with long-lasting trains, calls for some offbeat observing projects.
By Roger W. Sinnott
The thin crescent Moon sets early on the evening of August 12th, leaving the sky fully dark for this year’s Perseid meteor shower. The display should peak later that night for observers throughout the Northern Hemisphere, especially as morning twilight begins. That’s when the radiant (the patch of sky between Perseus and Cassiopeia from which the Perseids appear to come) is highest in midnorthern latitudes. Skywatchers can expect to see 60 or more Perseids per hour, provided the sky is very clear and dark.
If you miss the Perseids that night, all is not lost. The shower lasts for two weeks or so, with excellent rates in the predawn hours of August 10th through 15th. Far fewer meteors will appear before midnight, even on the night of the shower’s maximum, because the radiant is then quite low in the sky. The radiant is always low or below the horizon for countries like Australia, New Zealand, and South Africa, where few, if any, Perseids can be seen.
