There's a name for that though I can not - oh yeah - sun dogs.
Atmospheric ice crystals refracting the sunlight.
As a Canadian I can tell you it is damned cold out in that video, just by the sound his boots are making in the snow.
Cold snow crunches differently from warm snow.
I put that at about minus 30C or colder. Extra crispy cold.
When your nose hairs freeze. Also, you can freeze dry your laundry or go out with wet hair and comb out the ice. Hair is instantly dry.
Perfect weather for ice fishing:)
