A lunar Rainbow, also known as a moonbow, appears under moonlight over Upper and Lower Yosemite Falls - Yosemite National Park, California
It’s just about that time of year again when the moon makes rainbows in Yosemite valley. Moonbows are particularly magical because they’re almost invisible to the naked eye due to our limited night vision. It’s for this reason that when you review moonbow photos on your camera (assuming you’re shooting with a digital camera) the end result almost appears to be magical.
