Przewiduje się, że możemy mieć dodatkowe, wcześniejsze maksimum roju między 0800 i 0900 UT, 12 AUG - kilka godzin wcześniej niż to przewidywane na 1700-2000 UT, 12 AUG. Intensywność zjawisk może się nawet podwoić. To dobra wiadomość - dla amerykanów

This year's Perseid meteor shower could be even better than usual. "A filament of comet dust has drifted across Earth's path and when Earth passes through it, sometime between 0800 and 0900 UT (1 - 2 am PDT) on August 12th, the Perseid meteor rate could surge to twice its normal value," says Bill Cooke of NASA's Meteoroid Environment Office. The following profile is based on the debris stream models of veteran forecasters Jeremie Vaubaillon and Mikhail Maslov:
The filament was shed by Perseid parent comet Swift-Tuttle in the year 1610, and this is one of Earth's first encounters with it. "In addition," notes Cooke, "the main Perseid debris stream, which we run into every year, may be denser than normal due to a gravitational enhancement by Saturn. The total combination of these effects could result in as many as 200 meteors per hour (ZHR)."
