Fireball Across the Northeastern United States

With over 1500 reports of a fireball seen from Maine to Maryland, the American Meteor Society derived a geometric impact point of the incoming object to an area  south west of Carlisle, New York.  The fireball was seen at around 6:35 EST the evening of December 29th.  Many reports described the fireball as being greenish on color as it streak across the sky with a tail.  Others describe the fireball as being whitish in color.
