A YouTube user ('Finn Enoksen') shared video clip of strange sounds he recorded that seemed to come from the skies over Greenland on January 4th: "I hear that strange sound like for 1hour but sometimes it silence for 5 or 10 minute, it little bit hard to heard because that strange sound is not loud."
