This ice halo, encircling the sun, was observed yesterday while I was walking in St-Laurent looking for migratory birds.
Just a quick note on how ice halos come to be:
Ice halos are caused by both refraction, or splitting of light, and also reflection, or glints of light from ice crystals typically suspended in cirrus or cirrostratus clouds. The crystals have to be oriented and positioned just so, in order for the halo to appear. They can appear around the sun or the moon.
Here is another photo of this atmospheric phenomenon:
