Tonight's Moon Ring

I saw a lot of posts on Facebook tonight about a ring around the moon.  Here's the view from Indianola at 9:15pm.  It's sometimes called a winter halo, caused by the refraction of light from ice particles suspended in the atmosphere, in a way similar to the conditions that form a rainbow when sunlight refracts through raindrops.  Folklore holds that moon rings or winter halos warn of approaching winter storms.  It's said that you can count the number of days until the storm by counting the stars inside the ring.  While I'm not sure about counting the stars, I do know that our weather service is calling for a chance of winter weather on Christmas day.
