Sun Dog & Halo

While leaving the CAF hangar yesterday I noticed a “sun dog” near the setting sun as it shone through a layer of high clouds that had moved in. I was in bright sunlight but could still see the little rainbow-colored patch, so I moved into the shadow of one of the new hangars to take a photo.

Once in the shadow, my eyes adjusted a bit to the lower light, and I noticed the full 22° halo around the sun.

Caused by the sunlight passing through high-altitude ice crystals, I could see an identical (but dimmer) ring around the moon later in the evening. But it was too dim for me to get a good picture.
