I caught this Moonbow on camera near the small town of Stykkisholmur, Iceland on Sunday evening. I was driving in heavy rain and so much wind and I just stopped the car because I could not believe what I was seeing. First, I thought I was just seeing some reflection from the window of my car, but then me and my friend who was driving decided to stop and try to get a picture of it. I didn't have a tripod or any gear so I put my camera on the road and tried to hold it still in this crazy weather and this picture is the outcome.
Lunar rainbows are formed when moonlight, rather than direct sunlight, is refracted by moisture in the atmosphere. They are much harder to see than the daytime versions because moonlight is so much fainter, meaning they often look white to the naked eye, although the colors emerge in long-exposure photographs. Just wanted to share this because I have never heard of this until now.
