A nature lover taking photographs of clouds during a storm in the province of Groningen in the Netherlands noticed a flash while taking a picture. He knew it wasn’t the flash of his camera so assumed it was lightning. When he developed the shot, the flash appeared as a green jellyfish UFO.

Harry Clipperton blogs nature photos and that’s what he was planning to do with the storm shots he took while walking on May 19th in the town of in Onlanden. Instead, he posted it as a UFO sighting and it was picked up by a local news site and distributed around the Internet. While some describe it as a flying saucer, the green tail make it look more like a jellyfish UFO.

Norway had a similar sighting in 2010 of a UFO near the Northern Lights
