From Spaceweather.com:
Last week, a powerful blizzard paralyzed parts of the US midwest. Mike Hollingshead of Blair, Nebraska, walked outside after the storm and this is what he saw:
Sunlight shining through ice crystals had produced a bright pair of sundogs and a vivid circumzenithal arc. “These tend to appear on the backside of a storm’s clearing line as ice crystals blow through the air,” notes Hollingshead. “It’s a beautiful sight but not a ton of fun to photograph at 5o F with winds blowing 40 mph.”
