Colin Chatfield, who has posted many beautiful photos on our pages, wrote, “Sun halo from this afternoon [April 15, 2013] in Saskatoon, SK, Canada.”

Our friend Virginia Zepeda Vidal posted this sun halo seen April 15, 2013. She said, “This was the sun this morning on highway 43, near Meyerthotpe, AB, Canada.”
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.
