This week, the sky has shared some phenomena of light refraction and dispersion. Earlier this week, we had a band of heavy rain come through as the sun was low in the western sky which gave us some double-arching rainbows. This morning, while drinking my morning coffee, I see a bright sun-dog out of the corner of my eye. Popped out in the back yard and there was a rather bright halo around the sun. The clouds extending off the halo gave a nice effect. They say, 'ring around the sun or moon; rain or snow are coming soon'. This time, our forecast indicates sunny and warm temps for the next several days.
