I know many people have called and e-mailed about the ring around the moon. It was a glorious sight, with a fairly easy explanation.

Typically you see these optical displays when high cirrus clouds precede a storm system from the west. High cirrus clouds are composed of ice crystals, and they help refract the moon's light. This refraction causes the halo look around the moon. Since the ice crystals have a fairly uniform hexagonal shape, the moon ring is usually the same size.

Once a moon ring is spotted, weather folklore says that rain will be possible over the next few days. We'll have to see if this folklore is fact or fiction............
