Chasing a Fog Bow

Fog bows are said to be "incredibly rare". I put a photo of one on this blog yesterday. Here's how I saw that I might capture one. In this photo, one sees a fine mist approaching in the distance, towards me and towards the sun. Also, on the right in the middle of the photo, one sees a white glow which is, so to speak, unnatural. That is the beginnings of a fog bow. Rainbows turn white where there are very fine water droplets in the air -- less than 0.05 mm. They are also called white rainbows, or ghost rainbows.
