After Terrace in BC, strange sounds were heard, back in November 2013 in Saskatoon, Canada. And their source remain a mystery!

This is only the latest in a series of videos that have hit the web since early 2012 that capture strange but similar sounds around Saskatchewan. On the 9th of November 2013, thundering noises were reported and recorded by Ernie Werezak at around 5 a.m. in Saskatoon, Canada. They resemble the sound of the mothership in Close Encounters of the Third Kind, or the snarl of a long-dead dinosaur crawling back out of the Earth’s crust, or simply the wailing of the coming apocalypse.
Whatever it was – even if completely benign – the thundering sounds over Saskatoon recently were alarming enough, and loud enough, to stir Ernie Werezak awake and compel him to grab his camera and start recording. According to Werezak, who posted the footage on YouTube, he was jolted out of bed by the sounds, which he says seem to be ‘in the air,’ around 5 a.m. last Saturday.
Other youtube users also confirmed hearing the sounds.
What are the causes of this noise?
University of Saskatchewan physics professor Jean-Pierre St. Maurice told CTV News the cameras were likely picking up noise from an electrical antennae. The sounds could also be caused by electromagnetic noise in the ionosphere. It’s not actually noise! It’s like the electromagnetic waves emitted from the aurora above our heads or emitted by the radiation belt a little bit more to the south.
But for me it makes some noise! What about you?
