If the fireball and explosion witnessed by residents along the mid-Atlantic coast Sunday night was a meteor, it's likely that it survived to hit the ground, an astronomy expert says.
The explosions occurred one to two minutes after the fireball disappeared, which means that a meteor penetrated deep into the atmosphere, said Alan MacRobert, senior editor of
Sky and Telescope magazine. That makes it more likely that meteorites survived to hit the ground, although it is not certain.
MacRobert encouraged eyewitnesses to report what they saw at
American Meteor Society, or at
Spaceweather.com. Scientists can predict where to look for meteorites on the ground "if enough people can accurately reconstruct the flight path that they saw in the sky, or if they can simply say 'It went behind that tree,' " he said.
S. Kent Blackwell, an amateur astronomer, was sky-watching in Pungo when the explosion occurred around 10 p.m. Sunday.
"This brilliant green meteor was probably two or three times brighter than the full moon," Blackwell said. "Then it turned orange with a white core and disappeared."
