Halos around the sun or moon are a sign of high thin cirrus clouds drifting 20,000 feet or more above our heads. They’re pretty common. We see many, many photos of halos, especially in the winter months but also at other times of year. The two in this post are particularly nice, though. They are two solar halos spotted over separate parts of Canada, at different times of day, yesterday.

What makes a halo? Those high thin cirrus clouds 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.

The crystals have to be oriented and positioned just so with respect to your eye, in order for the halo to appear. In that way, you might say that each person sees his or her own personal halo.
