Ancient legends say the Northern Lights appear when the sky-dwellers light torches to guide souls to the heavens. Others say theyre animal or human spirits dancing or playing. Today we know the Aurora Borealis occurs when charged particles emanating from the sun interact with the Earths magnetic field. Still, we remain fascinated by these shimmering curtains of light. The Aurora Borealis The Magnificent Northern Lights square wall calendar captures this breathtaking phenomenon with stunning photos, allowing you a fresh glimpse each month of brilliant displays of colour and movement.
