Looking not unlike a smiley face, this upside rainbow made a rare appearance in the skies above Market Deeping, in Lincolnshire on Wednesday.
Known as a circumzenithal arc, the phenomena is similar in appearance to rainbows, but different in its formation.
The Met Office explains: “These are not rainbows but are examples of halos, formed by ice crystals high in the atmosphere.”
