The fogbow shown above was captured near Zeriki village on Mount Helicon (Elikónas) in central Greece. This was the first time I ever observed a fogbow. I felt quite fortunate to see it since just a few minutes later, it was lost in the mist. The tiny water droplets that compose fog (about .01 mm in diameter) act to primarily diffract light, so these soft bows don’t have the brighter, well-defined colors characteristic of rainbows, which result when sunlight is refracted in much larger raindrops (about 0.3 mm in diameter).
