A travel photographer captured this spectacular fire rainbow - a 'circumzenithal arc' - a phenomenon so rare he had to ask other experts what it was.

The unusual sighting of the horizontal rainbow was captured by Ukranian snapper Anton Jankovoy - using a camera set up with a large aperture to 'soak up' as much light as possible. The rare phenomenon is created by light reflected from ice crystals in high-up cirrus clouds.

'You do see circumzenithal arcs in the UK but not to this strength of colour, ' says a Met Office spokesperson. 'Several have been seen this year in the UK. They are produced when either light from the sun or sunlight reflected by the moon passes through ice crystals in the atmosphere.'
