A 46° halo is a rare atmospheric optical phenomenon that consists of a halo with an apparent radius of approximately 46° around the Sun. At solar elevations of 15–27°, 46° halos are often confused wit
Sun dogs with a larger and fainter 46° halo and a 22° halo with an upper tangent arc
The 46° halo is often confused with the supralateral arc (seen here with a circumzenithal arc, surrounding a 22° halo with a tangent arc and a Parry arc).
