Fog bow sightings were seen early Sunday morning. (1/25/20) Fog bows are different from rainbows in the sense that they have more of a whiter color appearance. The reason for this lies in the size of the water droplets. Fog has smaller suspended droplets of water than the larger rain droplets associated with normal rainbows. Because fog droplets are smaller, the rays from the sunlight are diffracted more. More diffraction equals less pretty colors.
