On New Year's Day, people in southwestern Pennsylvania heard an explosion around 11:20 a.m. EST.
People all over Pittsburgh took to social media, saying the boom was incredibly loud and shook their house. Others posted footage capturing the crackling sounds of the explosion.
The National Weather Service Pittsburgh noticed a flash captured by its satellite's Geostationary Lightning Mapper in neighboring Washington County.
"This flash does not appear to be connected to any lightning activity in the area. One possible explanation is that a meteor exploded at some level above the ground," the weather service said in a post on Facebook.
