Bill Cooke of NASA's Meteoroid Environmental Office said the widely-reported flash in the sky was probably "a single meteor event." He told the Associated Press:
[It] looks to be a fireball that moved roughly toward the South East, going on visual reports.
Judging from the brightness, we're dealing with something as bright as the full moon.
The thing is probably a yard across. We basically have [had] a boulder enter the atmosphere over the North East.
