Why, halo there. Halo around the sun
What do you call a rainbow formed by ice? An icebow, of course. Others call the phenomenon a halo, and we'll admit it does have a mystical aura. Halos can occur when ice crystals suspended in the air refract light into a colorful ring around the bright sun. That's what's happening in the cold atmosphere here in the Ore Mountains along the Czech-German border. It's a perfect complement to the snow angels you're yearning to make in this pristine blanket of white.
