This morning’s 5 a.m. walk featured a cool phenomenon: a ring around the moon. A china white half moon was high in the sky, and the ghostly, translucent, but clearly visible ring was a considerable distance out from the moon itself. The effect was liked a giant, lidded eye in the sky.
According to this website, moon rings are caused by refraction of moonlight from ice crystals in the upper atmosphere. They are associated with high altitude, cirrus clouds, which may explain why the stars looked somewhat indistinct this morning.
Folklore holds that a moon ring means that storms will be coming, and that the number of stars within the moon ring equal the number of days until the storm will arrive. I didn’t count the stars within the ring, however, so I won’t be able to put that folklore to the test.
