Cox, a Republican, said in a tweet he heard a loud boom while he was running in Salt Lake City early Saturday morning.
“We have confirmed it was not seismic/earthquake and not related to our military instillations,” his tweet continued.
The agency said the pixels are “not associated with evidence of thunderstorm activity in satellite or radar,” but they are likely a result of the meteor trail and flash.
Utah residents took to social media to share their videos capturing the loud boom heard in the area Saturday morning. One video, recorded by the Snowbasin Ski Resort’s web camera, captured the meteor streaking across the sky.
Residents in Salt Lake City and South Jordan, which is about 20 minutes to the south, told CNN they heard the boom. Doorbell and home cameras recorded the sound from 8:30 a.m. to 8:32 a.m.
