A group of halos, each of which passes through the anthelion.
Four mechanisms have been proposed for producing arcs of various shapes that nevertheless pass through the anthelion. Each of the four predicted shapes has been documented photographically. Each mechanism involves refraction and internal reflection in columnar ice crystals, but they differ in the particular crystal faces involved.
