NASA confirms the bright flash over the east coast Friday was likely a single meteor event. Reports say a fireball moved toward the southeast. Bill Cooke of NASA'S Meteoroid Environmental Office say that size of the meteor was roughly a yard across. The rock could have been the size of a boulder at initial impact with the atmosphere. More than 300 people reported the fireball sighting to the American Meteor Society. Reports described a flash of light visible for 7-10 seconds, crossing much of the sky.
