My trusty pooch and I observed this alluring fogbow over Sebago Lake, Maine, on the morning of April 15, 2022. Fogbows occur when light (sunlight, moonlight, streetlights, etc.) interacts with cloud droplets that are approximately 10 to more than 100 times smaller than a raindrop. Because these droplets are tiny, any coloration is wan. As with rainbows, in order to see these inconspicuous bows, the Sun must be at the observers back (180 degrees from the fogbow itself) even if it's hidden from view.
