I spotted this lunar halo tonight and knew that I would probably have only a few minutes to capture it. And I was right! In just 10 minutes, the clouds started to break up and the ring around the moon disappeared.
According to a most interesting article by EarthSky, "the halos you see are caused by both refraction, or splitting of light, and also by reflection, or glints of light from these ice crystals. The crystals have to be oriented and positioned just so with respect to your eye, in order for the halo to appear.
That’s why, like rainbows, halos around the sun – or moon – are personal. Everyone sees their own particular halo, made by their own particular ice crystals, which are different from the ice crystals making the halo of the person standing next to you."
So, this is my personal view of the lunar halo over my house tonight!
