Glimpses of a rainbow ring around the sun were an amazing sight as I drove through the Marsh today. The phenomenon lasted several hours.
Thin and wispy cirrus clouds are the culprit. These clouds are higher than 20,000 feet and are composed of ice crystals. Light passes through the crystals and is refracted, like light through a prism. When the light bends at an angle of 22 degrees it causes a sun halo, also aptly called a 22 degree halo.
It was colorful in the clouds and colorful reflected on the water.
