If you weren't outside around 10:15 p.m. last night, you may want to check your security cameras. If they're facing east, they may have captured footage of a rare fireball soaring — and dramatically exploding — in the sky along the east coast of Florida and the Bahamas. Late Monday evening, witnesses from Jacksonville to Miami reported seeing a fiery explosion illuminating the sky. Some heard a sonic boom. The fireball prompted calls to the National Weather Service and nearly 200 reports to the American Meteor Society. The fireball was likely a piece of an asteroid, technically called a 'bolide' because it blows up at the end, according to Mike Hankey, operations manager for the American Meteor Society.
