PITTSBURGH, PA– Did you see a fireball in the sky Tuesday morning? Some FOX 8 viewers emailed us asking what it was.

Now, NASA is revealing details. It says the bright fireball was seen over portions of Ohio, Pennsylvania and New York at 4:45 a.m.

Three NASA cameras captured it. The video you see above was captured from a NASA camera at Allegheny Observatory near Pittsburgh; NASA said the other two cameras are located at Hiram College and Oberlin College, both in Ohio.

On its Facebook page, NASA Meteor Watch says the fireball was a space rock about two feet in diameter and weighing about 500 pounds. It entered the Earth’s atmosphere above western Pennsylvania. NASA said it moved at a speed of 45,000 miles per hour and flared brighter than the full moon before cameras lost track of it.
