Quote: PACIFIC FIREBALL: On Tuesday morning, Feb. 19th, at approximately 5:30 a.m. Pacific time, people in Washington, Oregon, Idaho and Montana witnessed a spectacular fireball. It exploded not once but twice in midair, casting shadows and rivaling city lights. Many onlookers wondered if spy satellite USA 193 had been shot down. No, it was a small asteroid breaking up in Earth's atmosphere, a surprisingly common event. Reports of meteorites hitting the ground remain unconfirmed; stay tuned for updates
"I did not see the fireball itself, but I did observe two bright flashes over the eastern horizon like transformer explosions," reports climatologist Jan Curtis of Portland, Oregon. "They were as bright as city lights." Much is uncertain about this event. It was probably a small asteroid breaking up in Earth's atmosphere.
