What’s A Sun Halo?

What’s A Sun Halo?

Ever seen a ghostly rainbow halo around the Sun?

A Sun halo is caused by the refraction, reflection, and dispersion of light through ice particles suspended within thin, wispy, high altitude cirrus or cirrostratus clouds. As light passes through these hexagon-shaped ice crystals, it is bent at a 22° angle, creating a circular halo around the Sun. The prism effect of light passing through these six-sided ice crystals also separates the light into its various color frequencies, making the halo look like a very pale rainbow, with red on the inside and blue on the outside.

Folklore tells us Sun halos can predict the weather:

A ring around the Sun or Moon
means rain or snow is coming soon.

Sundog?

Occasionally, brighter areas will form along these halos, creating a mock Sun, or “sundog.” Sundogs are known as parhelia (or the singular parhelion) to astronomers, from the Greek words meaning “beside the Sun.”

    Yes, whilst I was in Florida, visiting my sister, at the beach, we were knee deep in water with her a 1yr. old, grand-daughter. We spotted a halo very weird and amazing.. Then out of the blue, we were wash by a riptide. We were able to rescue the baby and my sister to higher ground. It succeed to wash me under again. I am here to tell you, without the help of two strong young men and a female nurse telling them how to help me to safer grounds.

  • If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
