Meteor triggers sonic boom and "astonishing" flash of light across multiple states and Ontario - CBS News — A noontime boom that was heard and felt from southern Ontario to Virginia was likely caused by a disintegrating meteor, according to an organization in western New York that keeps track of such phenomena. Witnesses across the area reported hearing the boom or seeing a fireball in the sky shortly after noon on Wednesday, said Robert Lunsford of the American Meteor Society in Geneseo.
