These stunning pictures show a rare ‘flying saucer’ cloud hovering over an estuary.
The enormous cloud – which has been likened to the Starship Enterprise – was captured floating above the River Exe.
Known as a Lenticular cloud, it is an extremely rare sight in Britain but is believed to be one of the most common explanations for UFO sightings.
The images were taken by Stuart Woolger who noticed a “strange cloud formation” while cycling between Exmouth and Lympstone in Devon.
Stuart, 53, said: “I knew it was a Lenticular cloud because I had seen one many years ago in New Zealand, but had never seen one in the UK.
“Being a keen photographer I didn’t want to miss a chance of getting a shot of this amazing sight.
“I cycled toward the estuary taking a few shots on route, but wasn’t 100 per cent happy with them and carried on pedalling to find a spot where I could get a nicer photo.
“As I arrived in my home village of Lympstone the cloud came into full view. It looked so surreal sat stationery over the estuary towards Powderham Castle.
“It slowly decayed over the following few hours, but I felt lucky to see such a rare sight.”
The clouds form when the air is stable and the wind blows across the hills from the same or similar direction, at different heights of the troposphere.
They are a visible sign of mountain waves in the air and appear stationary, even when it’s windy.
