I was in the studio this afternoon working on wedding album designs when I decided to take a break and head outside to enjoy the beautiful spring day here on the Cape. I looked up and saw this amazing 22° solar halo surrounding the Sun..... I just had to run back inside and grab the camera! :-) To capture the wide field of view you see in the image, I used a 15mm fisheye on the Canon 5D which covers 180°.
A 22° solar halo is an optical phenomenon forming a circle 22° around the sun. It forms as sunlight is refracted in hexagonal ice crystals suspended in the atmosphere... usually from high altitude cirrus clouds.

Enjoy the view!
