Actually, this engine's helpful occultation of the Sun allowed for a crisp, clean view of not only the parhelion but a portion of a 22 degree solar halo and the a parhelic circle (extended tail of the sundog). (epod.usra.edu)

Sometimes, the Sunset is along with two colored luminous apparitions more or less contrasted. Located on the border of the halo located at 22 degrees of the Sun, on the right and on the left of it, they are called "parhelions" or more frequently "sundogs". (pixheaven.net)
