Aurora Borealis
If you’ve ever been near the North Pole, there are often beautiful light shows in the sky. These lights are called the aurora borealis. The aurora borealis is best seen at night, when it is actually caused by the Sun. The Sun doesn’t send out the same amount of energy all the time. When the magnetosphere is disturbed due to the solar wind, we see the light of the aurora borealis.
Auroras are sometimes seen in latitudes below the auroral zone, when a geomagnetic storm temporarily enlarges the auroral oval. Large geomagnetic storms are most common during the peak of the 11-year sunspot cycle, or three years after the peak.
