A rare weather phenomenon was spotted over Northumberland at the weekend.
Just before 8pm on Saturday January 7, a moonbow was spotted in the county's dark skies park close to Kielder Observatory. Moonbows, also known as lunar rainbows, occur when the light from the moon is reflected and refracted by water droplets at a certain angle to create a rainbow.
However, since the amount of light available even from a bright full moon is far less than the sun, moonbows are often incredibly faint and rarely seen - often appearing white to the human eye. Dan Monk, Kielder Observatory's astrophotographer, captured an image of the unusual sight on his iPhone.
