I'm lucky, because the fogbow is still visible when I leave the highway. I stop by a small road. Notice my shadow at the center of the gofbow, as for a rainbow.
Origin of the fogbow: A fogbow is form like a rainbow. The sunlight reflect in the fog droplets, but thoses droplets are much more smaller than the raindrops: about hundredths millimeters for the fog instead of about one millimeter for the rain. Thus, the diffraction in the fog droplets is leading, then the colors are refracted under angles between 30 and 45° around the antisolar point (at the opposite of the Sun). Then the colors mixe and one can see a white light bow, with sometime blue in the interior and red in the exterior, larger than a rainbow.
