A rare weather event known as a fogbow stunned Brits as they formed over UK skies at the weekend.
Thrilled visitors to the east coast of England were treated to crystal clear skies split by a see-through plume of colourless smoke arching overhead.
"On Saturday, the low cloud and fog thinned along parts of our coast, allowing the sun to break through, while fog persisted inland," BBC weather forecaster Dan Holley told the broadcaster.
"This created ideal conditions for fogbows."
Stunned Brits shared images on social media of the unusual sight, which was seen off the coast of Norfolk, Suffolk and Essex.
A fogbow is similar to a rainbow, except it appears as a bow in fog rather than rain.
It is created by the same process of refraction and reflection that creates rainbows, but formed instead by the water droplets in fog, mist or cloud, rather than raindrops.
These water droplets are much smaller than raindrops, nearly always less than 0.1mm in diameter.
Due to the small water droplets, fogbows appear mostly white, with a red outer edge and blue inner edge.
A similar spate of fogbow sightings took place in 2017, when the phenomenon was spotted over the skies of the Scottish Highlands.
A man initially thought he had seen a ghost when he was climbing a mountain and saw a figure looming out of the clouds.
Thomas Swallow, 39, was hiking with his friends but he'd got a bit ahead so was completely alone when he turned and came face-to-face with a ghostly apparition.
He said he was completely taken aback, but then realised his eyes were playing tricks on him - and what he was seeing was his own reflection mirrored back to himself.
What Thomas had seen, while climbing Great End in the Lake District, was a rare optical illusion known as a brocken spectre - where a large shadow of an observer is cast onto cloud or mist.
It comes as the Met Office predicts unsettled weather and a biting "snowbomb" that will give some parts of the UK a white Christmas this year.
Forecasters have said that some northern parts of the UK could see snow fall on December 25 while much of the country will be "cold and bright".
Unsettled weather in the build-up to Christmas is predicted to give way to colder, clearer conditions on Christmas Day.
A "snowbomb" is then forecast to strike the nation in the week before New Years Eve, some experts predict.
