The American Meteor Society has verified over 300 witness sightings of a meteor in at least 13 US states.
Stretching from Ontario down to the southern state of North Carolina, there are still over 100 reports yet to be reviewed, said Mike Hankey, an observer for the American Meteor Society.
"This was most certainly a fireball seen over a good portion of the eastern states," said Robert Lunsford, the society's fireball coordinator.
"It happened at a good time, around 8 o'clock on a Friday night, when a lot of people were out to see it," Lunsford said.
