A.K.A. Northern Lights
Basics Information on Aurora Borealis
The best time to view the Aurora Borealis is in Spring or fall, late at night or early in the morning. Between the months of Deecmber and March, Alaskan nights are longest and the sky is the darkest. Usually when the sky is clear and the air is chilly, you can see the best light show.
In addition to the Aurora Borealis light show above the Northern Hemisphere, there is the Aurora Australis. It can be seen above the magnetic pole of the Southern Hemisphere.
By tracking the solar wind data and using magnometers people can forecast how the lights will be up to an hour ahead of time.
