Look what Rick, brother Bob, friend Cathy and I saw today as we walked the beach on Isle of Palms!
Thank you Cathy for catching this on your iPhone! It's called a fog bow and is just like a rainbow, except that because the particles are so uniformly small they make a white bow rather than colored. It, like others of its kind, does have a little pink and blue in it. They are relatively rare, but happen more often near or on the ocean, and in the Arctic.
