Encyclopedia > Fog bow
A fog bow, solar glory and Brocken spectre observed at the Golden Gate Bridge in San Francisco.
A fog bow and solar glory observed in San Francisco.

A fog bow is similar to a rainbow, but because of the very small size of water droplets that cause fog, smaller than 0.05 mm, the fog bow has no colors and appears white. Fogbows are sometimes called "white rainbows" or "cloudbows". Mariners sometimes call them "sea-dogs."
