#RAINBOW AT #NIGHT: Have you ever seen a rainbow after dark? On Aug. 18th, Aaron Watson of Paonia, Colorado, saw two of them:

Rainbows appear when sunlight is reflected from falling raindrops. In this case, the sun was not required. "I woke up to the sound of rain with the nearly full Moon beaming through the window," says Watson. "It was the perfect recipe for a #moonbow."

In fact, it was a double moonbow. Single moonbows are caused by single reflections inside raindrops. Double moonbows like Watson saw are caused by double reflections. "It was vibrant and colorful even to the unaided eye and lasted several more minutes as it slowly faded," says Watson.
