We have rainbows, moonbows, and yes, even fogbows. USFWS writes, "Fogbow centered on South Valley Road in Red Rock Lakes National Wildlife Refuge. Fogbows form in the same way as rainbows. A small fraction of the light entering droplets is internally reflected once and emerges to form a large circle opposite the sun. Fogbows are formed by much smaller cloud and fog droplets than the raindrops that form rainbows."
