Several WHNT News 19 viewers, including Ramona Edwards and Tressi Downs, shared pictures with us of a large ring around the sun.
This optical feature is called a 22-degree sun halo.
Earthsky.org explains it very simply:
Halos are a sign of high thin cirrus clouds drifting 20,000 feet or more above our heads. These clouds contain millions of tiny ice crystals. 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.
