Circumzenithal arcs, are considered the most beautiful of the haloes. The CZA is never a complete circle; the centre of the bow is always sunwards and red is on the outside. The zenith is a circle around the point in the sky directly above the viewer.     Downcoming sunrays enter the uppermost horizontal face and then leave through a vertical side face. The result is the refraction of rays that produce very pure and well-separated prismatic colours.

The circumzenithal arc or circumzenith arc (CZA), also called the Bravais' arc, is an optical phenomenon similar in appearance to a rainbow. It forms no more than one-quarter of a circle centered on the zenith and on the same side as the sun. Its colors are from blue on the inside to red on the outside of the arc. The first impression is that of an upside-down rainbow.
