Dashcam footage showing a bright white and blue flash over the city of Stavropol has gone viral.
The peculiar spectacle lit up the whole region on Monday night and was so powerful that it even knocked out some of the street lights. The event was captured on film from the dashcam of a car that had been approaching the city at the time of the incident.
Since appearing online the video has generated several hundred thousand views with Internet users debating over what might have been the cause of the phenomenon.
Some have suggested that it could have been something to do with military exercises being carried out in the region while others put forward the idea that a light show at a nearby concert that was happening on the same night may have been responsible.
"It wasn't a meteorological event, there wasn't a storm," said Natalya Klimenko, an analyst at the Stavropol Meteorological center. "More likely it is something made by a human being."
