When the clouds of solar particles reach Earth, they are deflected back by the planet's magnetic field. The collision sends electrons trapped inside the field spiraling down to the North and South Poles. The electrons fall to Earth and slam into atoms in the atmosphere, producing X-rays and the shimmering waves of auroras visible across the night sky. Auroras seen in the Northern Hemisphere are called "aurora borealis," while those observed in the Southern Hemisphere are known as "aurora australis." Northern Lights...Anyone ever really seen them?AB?</blockquote>
