A rare white rainbow has been pictured over a seaside resort in Gwynedd.

The meteorological phenomenon was spotted by people in Tywyn on the Cardigan Bay coast on Thursday morning.

Also known as a fogbow, cloud bow or ghost rainbow, the arc is formed when sunlight interacts with small water droplets contained in fog, mist or cloud.

It differs from a a classical rainbow which is created when sunlight interacts with raindrops.
