HAL is a StarChild
Abisko National Park, northern Sweden... The two bright spots on either side of the Sun are parhelia (singular parhelion), also known as mock suns or sun dogs. The parhelia are caused by hexagonal ice crystals suspended in the hazy atmosphere that reflect and refract sunlight. Commonly seen in winter and at high latitudes, the bright parhelia lie along the visible 22 degree ice halo of the Sun.
