Particles on the solar wind are captured by the earth's magnetic field and carried to the polar regions, where they form an "auroral oval" around each pole.
Your chances of seeing the greatest displays of the northern lights are increased if you find yourself above 40° north latitude and away from city lights.

Though auroral displays may occur at any hour, the best time to see one is the middle of the night.

Though the earth's magnetic field is unpredictable, with a little desire and a little luck, people all over the country may get a chance to see the sky's greatest display.
