Starting at around 7:30 tonight a loud noise could be heard coming from East Superior. Here is what it was.

The noise lasted about an hour and while some people posted on social media wondering where the sound was coming from and what it was, others called Superior Police.

Superior Police posted an update on Facebook after investigating the noise. It appears that the sound was created by a faulty air horn on the American Spirit that was docked behind the McDonald's at E. 2nd St. at 21st Ave. in Superior.

Thankfully everyone can sleep in peace and hopefully they got the problem fixed. Here is some video of the ship and the sound.
