Halos are a sign of high thin cirrus clouds drifting high above our heads. The clouds contain millions of tiny ice crystals, which both refract (split) and also reflect sunlight.

Göran Strand in Sweden posted this photo of a wonderful solar halo to EarthSky Facebook this week (July 26, 2015). He wrote:

Yesterday while I was documenting the ongoing Storsjöyran [a music festival], I saw a faint solar halo that was slowly growing in strength. This statue placed in Badhusparken, Östersund, and is called the Father and Son.
