I used "Live View" and not through the view finder.

From Wikipedia:
"A 22° halo is a halo, one type of optical phenomenon, forming a circle with a radius of approximately 22° around the Sun, or occasionally the Moon (also called a moon ring or winter halo). It forms as sunlight is refracted in millions of randomly oriented hexagonal ice crystals suspended in the atmosphere."

Seen during yesterday's Rocket Day shooting.
