- The best chance to see the lights is in northern U.S. states such as Alaska, Washington, Idaho, Montana, and Minnesota.
- If the storm gets stronger, the aurora may be visible as far south as Oregon, Nebraska, Illinois, and New York.
- The colors of the northern lights depend on the gases and height in the atmosphere where the particles collide.
- Viewing is best late at night, especially between 10 p.m. and 2 a.m., away from city lights and with clear skies.
