The supposed UFO was caught on camera by an eyewitness travelling at night through the province of Leon in northern Spain. The video was then uploaded to YouTube where the eyewitness said the anomaly was caught on the road between Truchas and Quintanilla de Yuso. The video shows a large, circular cloud with a flat bottom and almost dome-like top.
And although at first glance it appears to be nothing more than a lenticular cloud, some UFO hunters are convinced something extraterrestrial is afoot.
In particular, self-titled UFO expert Scott C Waring of UFO sightings believes this is an alien ship cloaked in clouds for disguise.
Mr Waring is a firm believer aliens are alive and well throughout the solar system and frequently visit our planet.
He even suggested the cloud UFO has a base under the ocean floor.

The UFO hunter said: "What we see here is a huge UFO that has created a cloud around it in order to not frighten the public.
"It probably is moving from a base under the ocean floor to a new location.
"The object also seems to be moving very fast, too fast to be a cloud.
"The disk itself is perfectly balanced and mimics the alien disk shape perfectly. This is an alien ship."
However, this is not the first time Mr Waring has dubbed perfectly innocuous clouds alien UFOs.
