Fogbows form opposite the sun in a manner similar to rainbows, except the water droplets that create a fogbow are much smaller than raindrops. Because a fog droplet is so small, the physics of the interaction is different. The result is often a diffuse, primarily white bow.

The photograph of the fogbow was taken Sunday morning on an out and back run from Wendy Drive to Mugu Peak. The sun was about 14 degrees above the horizon. More about fogbows and other atmospheric phenomena can be found on Les Cowley’s Atmospheric Optics website.
