Camera phone footage of mysterious lights hovering off the coast at Land's End has appeared on video-sharing website YouTube
The four minute clip, shot by an unknown UFO spotter, feature two lights - one small and circular, the other larger and dish-shaped.
Towards the end of the video, the smaller light appears to move towards the dish shape before disappearing beneath its glow.
Viewers have compared the lights to those seen during the "Gulf Breeze UFO incident," when a wave of UFO sightings were reported in Florida 25 years ago.
Others, such as commenter Jack Scholze, were more sceptical - "Its a balloon, and of course it is fuzzy, nobody ever seems to have a good camera handy when the unknown manifests," he said.
