Details:
Afternoon fog moving through Calgary, Canada at a ground temperature of -5.5C provided ice crystals at the fog boundary, giving us a spectacular atmospheric optics display for such "warm" temperatures. With a 22° Halo, Upper Tangent Arc, Parhelic Circle, Infralateral Arc and a suspect 46° Halo.
