An aurora (plural: auroras or aurorae) is a natural light display in the sky, particularly in the polar regions, caused by the collision of charged particles directed by the Earth's magnetic field.
The best months to see Auroras in Alaska are March and December when the nights are long with clear skies and milder weather. Fairbanks, Alaska is in a prime location for viewing the Northern Lights if you can get away from light pollution.
Here is a list of tours and resorts specifically for viewing the phenomenon.
