An incredible "fogbow" was spotted over Biddulph this week.

The fog rainbow, which is also sometimes called a white rainbow, was photographed over Church Road playing fields by local resident Tina Beckett on Monday morning (20th September).

This kind of rainbow sometimes appears when light reflects off fog rather than rain, and is a rare sight, with several residents commenting that they had never seen a rainbow of this kind before.

Because of the very small size of water droplets that cause fog, the fogbow has only very weak colours, and can often appear as a white arc in the sky, like a colourless rainbow.

The Met Office explains on its website: "A fogbow is similar in some respects to a traditional rainbow forming from sunlight interacting with water droplets contained in fog, mist or cloud rather than interacting with raindrops as it does in a classical rainbow.

"These water droplets are much smaller than raindrops, nearly always less than 0.1 mm in diameter.

"These tiny droplets cause the light to undergo different physical processes, most notably diffraction, which leads to fogbows appearing to be devoid of colour. It is for this reason that fogbows are sometimes known as white rainbows."
