A Sundog is called a “PARHELION” in Greek. Meaning “Beside the Sun”!
Sundogs occur in the 9 & 3 clock positions,with the sun being in the centre.
Sundogs occur as a result of flat plate like (hexangle) ice crystals high up in the atmosphere. When these ice crystals (Diamond Dust) are randomly oriented,a halo around the sun occurs. However,if these crystals descend & orientate themselves vertically,the light is refracted horizontally & thus a Sundog is born.
Sundogs tell of a weather change about to occur.
