The right place at the right time with the right equipment is the only reason I was lucky enough to capture the image above. I was in my car yesterday with my trusty camera by my side when I noticed a Solar halo forming, pulled over to the side of the road, got out and was starting to take the picture of the halo. As I was imaging the Solar Halo, image below, with an Upper Tangent Arc, a Second halo with a Circumzenithal Arc started to form before my very eyes, zoomed out to get the whole picture in the same frame, what a sight!!! I had decided to start carrying my camera equipped with a fisheye lens around with me 24/7 just in case something like the above were to happen, and it did.
Circumzenithal Arc, aka "A Smile in the Sky" the most beautiful of all the ice halos, sits on top the 46 degree halo/arcs. Formed by the Sunlight refracting off horizontally orientated ice crystals in the high wispy Cirrus clouds. They go unnoticed a lot of the time simply because they hang high around the Zenith, plus again, they come and go real fast, the one I imaged above lasted 10 minutes tops.
Saskatoon in the winter, this -25c weather is good for something. As I was heading for work in the morning, I noticed the lights from the city reflecting off some low clouds and a Lunar Halo, made for a pretty picture, so having my 24/7 camera with me I took the pic. I liken the Solar/Lunar Halos in the winter to the Milky Way in the Summer, both the best all encompassing celestial sky shows going.
I'll leave you now with an animation of my Double Halo.
