February 3 - Scattered Halo

Scattered Halo - Unlike sundogs, sun halos are created when sunlight passes through ice crystals that are oriented at different angles. This scatters the light in many directions and produces a halo. Frequently seen around the Sun, they occasionally form around the Moon as well.

Sundogs - an atmospheric phenomenon that creates bright spots of light in the sky (aka Mock Suns), often on a luminous ring or on either side of the Sun. Sundogs occur when the Sun is at a 45 degree angle and at its lowest point on the horizon. As the sun rises higher the rays passing through the crystals are increasingly skewed from the horizontal plane. Their angle of deviation increases, and the sundogs move further from the sun.
