\n\t\t\t\t\t\tIf you were in Western Pennsylvania, you may have seen what has been described as a fireball across the sky. In parts of Ohio, people reported hearing a boom and felt shaking.

NASA’s website describes a Geostationary Lightning Mapper, or commonly called a GLM, as “a single-channel, near-infrared optical transient detector that can detect the momentary changes in an optical scene, indicating the presence of lightning.”GLM measurements also help officials improve their tornado and thunderstorm lead times and can give an early warning of lightning ground strike hazards.
