Every August, when many people are vacationing in the country where skies are dark, the best-known meteor shower makes its appearance. The annual Perseid meteor shower, as it is called, promised to put on an above average display this year.
A very good shower will produce about one meteor per minute for a given observer under a dark country sky. Any light pollution or moonlight considerably reduces the count.
The August Perseids are among the strongest of the readily observed annual meteor showers, and at maximum activity nominally yield 50 or 60 meteors per hour. However, observers with exceptional skies often record even larger numbers. Typically during an overnight watch, the Perseids are capable of producing several bright, flaring and fragmenting meteors, which leave fine trains in their wake.
The time of the closest approach should be 4:50 p.m. ET (20:50 GMT) on Aug. 11 and could last about 40 minutes, favoring observers in Eastern Europe, eastern North Africa eastward to central Russia, India, and western China.
