Here is my weekly weather quiz question for the last time. What is a “Halo?” Here is the correct answer. A Halo of is any of a variety of bright circles or arcs centered on the sun or moon, caused by the refraction or reflection of light by ice crystals suspended in the earth’s atmosphere and exhibiting prismatic coloration ranging from red inside to blue outside. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.
