"A streak of silver and then a flash with crazy colors." That's how one person on Twitter described the celestial phenomenon seen by thousands of people across five states.
Around 12:30 p.m. Monday a fireball appeared in the sky over Pennsylvania, traveling east for hundreds of miles.
The Internet lit up with reports of sightings from people in Connecticut, New York, New Jersey, Pennsylvania and Maryland.
Scientists say it most certainly was a large meteor, a piece of an asteroid or a comet that falls through the earth's atmosphere.
This latest meteor, one scientist says, was probably the size of a car and from its trajectory likely landed somewhere in the Atlantic Ocean.
Professor Jon Friedrich says while meteors fall to earth on a daily basis, "It is unusual to see one so bright in the middle of the day."
