Sun halo fragments, clockwise from upper left…

Sun halo fragments, clockwise from upper left: A sundog to the left of the sun, part of a 22° circular halo to the right, and what I think is part of a parhelic circle in the opposite direction. I’ve seen the first two often enough, even here in #losangeles, but this is the first time I’ve seen the latter, which is a white circle that appears at the same altitude as the sun. #Halos like these are caused by reflections inside ice crystals, sometimes near the ground and sometimes in the upper atmosphere. #sky
