They are formed when sunlight refracts through horizontal ice crystals at such an angle that the light enters the crystal through its flat top face and exits through a side prism face causing the distinctive upside-down rainbow effect. Circumzenithal arcs are relatively common, though a special set of circumstances are required. The sun needs to be more than five, and less than 32 degrees above the horizon, in order that the sunlight can refract in the correct way through the ice crystals to form the smiling, rather than frowning, halo
