Officials at the Marshall Space Flight Center in Huntsville, Ala., said a baseball-size fragment of a comet entered Earth's atmosphere above Alabama at 8:18 p.m. CDT Monday.
NASA officials said the meteor traveled at a speed of 76,000 mph. They say just three seconds after hitting the atmosphere, it disintegrated 25 miles above the central Alabama town of Woodstock, producing a flash of light.
NASA spokeswoman Janet Anderson said that because it penetrated so deep into Earth's atmosphere, eyewitnesses heard sonic booms.
Music fans at a Mumford & Sons concert in Pelham, Ala., Monday night also reported seeing a flash of light.
