The fireball that blazed across the Texas sky and sparked numerous weekend calls to law enforcement agencies now can be considered an identified flying object.

The Federal Aviation Administration said Monday the fireball was a natural phenomenon — not flying space junk — and a North Texas astronomer said more specifically that it was probably a pickup truck-sized meteor with the consistency of concrete.

The object was visible Sunday morning from Austin to Dallas and into East Texas.

In Central Texas, the Williamson County sheriff's office received so many emergency calls that it sent a helicopter aloft to look for debris from a plane crash.

The FAA backed off its weekend claim that the fireball was caused by falling debris from colliding satellites plummeting into earth's atmosphere.
