White rainbow: Fogbow captured in Tywyn, Gwynedd
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.
