It may look like a rainbow against a stormy sky but this photograph shows an elusive midnight MOONBOW.
The rare natural phenomenon was captured by fisherman Johnny Simpson as he scanned the night sky for auroras in the Shetland Isles.
The arc appeared to rise out of the sea, rise over the tiny island of Whalsay, and end in the garden of a house.
Johnny, 55, said: “It was midnight and I was looking for auroras as they were supposed to be about in the sky but it was the moonbow that caught my attention.
“It was a surprise to actually see one. It was beautiful, even though it was very faint to see.”
Unlike a rainbow which forms when sunlight refracts off water particles, moonbows are created by reflected moonlight and have a fainter and more diffused colour.
