A massive lenticular cloud resembling a UFO was spotted over the city of Bursa in Turkey on Thursday, surprising citizens who captured the rare phenomenon on their phones. The circular cloud, which appeared at sunrise and featured a large hole in the middle, remained intact for about an hour. Lenticular clouds are known for their curved, flying saucer-like appearance, and are usually found at heights of between 6,400ft and 16,500ft.
