A video of a mysterious flash and a sonic boom spotted in the sky has caused a stir amongst experts.

Minnesota residents took to social media to express their concern at seeing the bright light and hearing the deafening ‘sonic boom’ over the sky in Beltrami County on Monday night (November 13).

Residents across a 50-mile radius also reported the incident to authorities.

While many people have come up with their own theories for what it is, from aliens to missiles, some experts have admitted they are not quite sure what the phenomenon was.

The public safety office, Beltrami County Emergency Management, shared two separate videos of the incident being caught on security cameras.

Two of the clips have begun circulating on X, formerly known as Twitter, and have been viewed more than 40,000 times since being posted on November 15.

The first snippet came from the Bemidji Regional Airport, four miles to northwest of Nymore, appears to show a white streak moving rapidly across the screen, past the airport.

The second clip was a security video from a private residence in Nymore, south of Lake Bemidji, and shows a bright streak of light followed by a loud bang, thought to be the sonic boom.

Local physicist Juan Cabanela, weighed in on the videos and told the Mail Online it is unlikely to be a meteor in the footage.

“I still don’t know what it was, but I was fairly confident it couldn’t be a meteor,” she said.

Chris Muller, director of Beltrami County Emergency Management, spoke to the Mail Online about the incident and came to a similar conclusion as Cabanela.

Muller said: “This video was provided to an astronomer and a scientist from NASA.

“They analyzed the video frame by frame and determined the object is too horizontal to indicate it was a meteor,” he said. “It is undetermined if the two videos are related.”

Muller also said the public safety office is considering the possibility that the airport footage doesn’t capture anything in the sky and has a rather boring explanation.

“There’s nothing that would have been interfering with the video camera, such as a wire or something like that reflecting light,” he continued.

“But one obvious thing is that bugs were flying around. And there were other bugs before that one. And it just so coincided that the timestamp on that was the exact same time as the other reports

“You’ll notice it does not go past the pole. So it’s probable that that bug just landed on that pole.”

However, Muller’s bug explanation doesn’t account for the multiple reports of residents who claimed to see something streak across the sky at a rapid speed or the thunderous boom hear
