The photo above, taken by Joshua Thomas, is of a sunrise in Red River, New Mexico. But it's not simply a beautiful photo. A number of optical illusions are captured in the image, namely a 22ยบ halo, a sun pillar, a sun dog, infralateral arc, supralateral arc, helic arcs, sunvex parry arc, upper suncave parry arc and upper tangent arc.
After the photo was posted to Facebook by the National Weather Service in Amarillo, Texas, the National Weather Service in La Crosse, Wisconsin created the graphic below, labeling the phenomena. Visit their post of the graphic here, see this site for additional information, and click on the terms above for definitions.
