This was one of the most intense sun halos that I have ever seen. The desert mid-winter day was pleasantly warm, but high in the atmosphere were sufficient ice crystals to form a ring of refracted light. A steep foreground ridge blocked the direct light of the sun, making the half-circle vivid against the wispy cirrus clouds and deep blue sky. The colors of a sun halo are not nearly as intense as those of a rainbow, but they can be faintly discerned in this photo.
This photograph was published on the back cover of the music CD Ring Around the Sun by Tim Flannery in February 2005.
