What are sundogs and why do we keep seeing them?

(Jackson, Wyo.) - Have you seen the cool ground rainbows and bright spots of light around Jackson lately? We were wondering what those were, so we asked Mike Maurer, the secretary treasurer for the Jackson Hole Astronomy Club. "A sundog is like a Rainbow," said Maurer. "Except that the phenomena is between you and the sun. It is Refracted Sunlight. The Refraction is from Ice Crystals instead of Water Droplets. The Ice crystals need to be oriented in the same direction. So calm air is required."

So does the temperature inversion with the super cold air close to the valley floor. Cold, Calm, Sunlight," he added. And when it is cold and calm outside at night, we can see another ice crystal phenomena, light pillars. You can see these reflecting off lights in town at night and creating a beam of light up into the sky. Here are some recent shots of light pillars, thanks to Maurer.
