A mysterious boom that could be heard across northern Utah and southern Idaho on Saturday was likely a meteor, the National Weather Service said. There was no seismic activity recorded at the time of the sound, but a Utah woman captured on video a bluish streak of light across the sky, and a satellite lightning detector also picked up on the activity. Utah Gov. Spencer Cox said he heard the boom while out running and checked to ensure it was not military activity. He agreed it was probably a high-altitude meteor hitting earth’s atmosphere.
