Night rainbow pictured in North Yorkshire

Amazing picture taken by a British from New Yorkshire who managed to "catch" a rainbow at night. As well known, a rainbow is generated when the sunlight is reflected off the water droplets but in this picture it seems that the moonlight created the rainbow phenomenon.
Chris Walker was driving on his way home in Richmond, New Yorkshire when suddenly spotted the rainbow in the rainy dark. Usually the moonlight rainbows are very rare due to some required conditions such as a combination of very dark skies, the moon located at less than 42 degrees in the sky and the rain falling opposite the moon.
