Last night's Harvest Moon was so bright, it did something normally reserved for the sun. It made a rainbow:

"I was surprised to see a rainbow at night," says Marsha Adams of Sedona, Arizona, who took the picture nearly 2 hours before sunrise. "The rainbow was apparently caused by the Harvest Moon beaming through the rain clouds."

Indeed, moonlight reflected by raindrops breaks into the colors of a rainbow just like sunlight does. It takes an especially bright Moon, however, to make the phenomenon visible to the human eye. Did anyone else spot a Harvest Moonbow? Submit your images here.
