Details:
By afternoon conditions were producing a sky full of ice crystals and our high for the day was -6F. A beautiful 22 degree halo and sundogs started developing just after 12:30PM ADT. But the best showed up starting around 4:00PM and lasted for an hour as a 360 degree Parhelic Circle developed and added two 120 degree Parhelia as well as a bright Circumzenithal Arc and what I think is a 46 degree halo. Elevation of the sun in the two photos is about 19degrees.
Camera Canon 5D Mk3 lens Canon fisheye 8-15mm zoom. All sky photo was taken at 8mm 1/350sec. f/13 ISO200, close up 15mm 1/500 sec. f/16 iso200.
