Met Office mystery over rare ice circle formed in Devon
.
An unusual rotating ice circle, normally found in the cooler rivers of Scandinavia or North America, has formed in the UK waterways.
.
The cause of the rare phenomenon is unclear, with very little scientific evidence available to explain the formation of the discs. UFO-enthusiasts claim that, like crop circles, the perfect discs are created by visiting aliens, but scientists believe the extreme cold weather combined with an unusual current is the more likely reason.
.
The 10ft disc was seen by a rambler on the River Otter in Devon, who estimated that it was spinning through 360 degrees every four minutes.
.
The Meteorological Office said today that they could not explain why the ice circle appeared last week.
