In the sky above the Wicken Fen reserve in Cambridgeshire, located in the east of England, there was an amazing “fiery rainbow.
One of the eyewitnesses managed to capture this amazing spectacle in the photo. Pictures quickly gained popularity in social networks.
“Fiery rainbow” is officially called a round-horizontal or okologorizontalnoy arc. This is one of the halo species. For the appearance of a relatively rare optical phenomenon in the atmosphere, certain conditions are necessary: the sun should be above 58 degrees above the horizon, high light clouds must also be observed in the sky, and flat hexagonal ice crystals should be located horizontally in them.
