KITTANNING — Fireball!

A meteor moving at 45,000 mph lit up the sky over Western Pennsylvania early Tuesday.

Its bright flare would have been visible in Butler County as it crossed the southern part of the county.

NASA’s Meteoroid Environment Office said the space rock measuring two feet in diameter and weighing roughly 500 pounds entered Earth’s atmosphere above Pittsburgh’s suburbs about 4:50 a.m.

NASA meteor cameras detected the rock at an altitude of 60 miles above Beaver Falls and captured it flaring brighter than a full moon as it moved to an altitude of 13 miles above Kittanning.

The agency says the meteor’s orbit indicated it came from the main asteroid belt between Mars and Jupiter.

NASA says meteorite fragments may be scattered on the ground east of Kittanning in Armstrong County.
