Check out the latest images at the live aurora webcam page.
The Aurora Borealis , also known as the Northern Lights, is a luminous, radiant emission from the upper atmosphere that is observed in the northern hemisphere in the winter. Most often observed as a pale green-yellow glow (as in the above picture) the Northern Lights can also reach richer shades that include reds.
In the Southern Hemisphere the lights are known as the aurora australis.
According to a publication on the Aurora by NOAA the Eskimos of North America believed that if one were to whistle at the aurora it would sweep down and take them from the world. A clap at the Aurora could cause it to move away. The publication does a very good job of describing what the aurora is and how it works, including why it is most often green with occasional flares of red color and even, on occasion, blue.
