What Makes A Rainbow Around The Sun?


By By Steve Pool

SEATTLE - You've all seen rainbows on those days where it's raining and the sun's out at the same time. But what about those times when you see a rainbow-like halo around the sun or moon?

It's the same physics, really. The halos are usually seen when there are high clouds overhead. Those clouds are made of tiny ice crystals, which will refract the sunlight much like a prism will.

Those same high clouds can cause a rainbow halo around the moon as well.

It can be a sign that rain is on the way, as high clouds usually precede a storm front.

Each year since 1998 our family has a tradition of putting up a scarecrow in our front yard during the month of October. We decide as a family what character we are going to do and it's a family secret until he goes up. Most of the time we create the entire outfit from scratch.
