Did you know that rainbows can occur at night? These phenomena are called moonbows, or spray moonbows if they form around falling water. Spray moonbows are the easiest kinds of moonbows to spot and photograph, and they reliably occur at the waterfalls in Yosemite National Park. The moonlight that creates moonbows is reflected sunlight, not direct sunlight, which explains why they are dimmer than regular rainbows.
