Dozens of skywatchers — including some armed with video cameras — reported seeing a bright fireball streak across the skyline on Monday evening. The American Meteor Society fielded more than 300 reports from across the Midwest and East Coast.
Bill Cooke, head of NASA's Meteoroid Environments Office in Huntsville, Alabama, told ABC News their reports suggest two separate fireball events occurred, one at 6:20 EST over the Southeast and Midatlantic, and another an hour later at 6:20 CST over the Midwest.
The first event appears to have been the most significant, the product of a meteor; it was witnessed from Georgia to Ohio. A large number of the reports mention the fireball possessed a green hue as it burned the in navy sky just above the horizon.
The second event appears to have been smaller and more isolated, lighting up the skies near Chicago.
"The Chicago event appears to be a slow mover; could be a piece of space junk," Cooke explained. "We're checking into that as well."
