The aurora borealis is actually a very common occurrence on Earth; it is said that auroras occur almost every day. However, their light is so faint that they are outshined by the sun when they happen in the day. Therefore, the best times to see auroras occur in the winter, when nights are longest. Auroras also become more frequent when the sun is most active during its 11-year cycle.
The aurora borealis can also phase, so the effect is stronger in different parts of the world depending on the year. The “auroral oval” is centered around the northern geomagnetic pole. When the sun is highly active, the oval spreads south down to Canada and the 48 states.
The second link below actually shows where the auroral oval is currently. Pretty cool to see!
