Fireballs & Meteors

Space Weather News for Nov. 18, 2009

FIREBALLS AND METEORS: As forecasters predicted, the Leonid meteor shower peaked during the late hours of Nov. 17th, favoring sky watchers in Asia with an outburst of 100+ meteors per hour. Just as the outburst was dying down, an even bigger event took place over the western USA. Something hit Earth's atmosphere and exploded with an energy equivalent of 0.5 to 1 kiloton of TNT. Witnesses in Colorado, Utah, Idaho and elsewhere say the fireball "turned night into day" and "shook the ground" when it exploded just after midnight Mountain Standard Time. Researchers who are analyzing infrasound recordings of the blast say the fireball was not a Leonid. It was probably a small asteroid, now scattered in fragments across the countryside. Efforts are underway to measure the trajectory of the asteroid and guide meteorite recovery efforts.

Leonid Meteor Shower Nov 17th

Space Weather News for Nov. 16, 2009

LEONID METEOR SHOWER: The Leonid meteor shower peaks on Tuesday, Nov. 17th, with a new Moon providing ideally-dark viewing conditions. Forecasters expect a relatively mild display (20 to 30 meteors per hour) over North America followed by a much stronger outburst (100 to 300 per hour) over Asia. No matter where you live, the best time to look is during the dark hours before sunrise on Tuesday morning.
