There is a gigantic rainbow ring around the full moon tonight.
The farmer's almanac calls this a lunar halo. It is caused by the refraction, reflection and dispersion of light through ice particles. The rainbow is red on the inside of the ring and blue on the outside. According the the almanac a halo foretells stormy winter weather.
I guess we shall see.
But right now I better get the non-sleeping kids to take a peek. It is too pretty not to share.
