Auroras are typically described as slowly shimmering curtains of light illuminating the sky. However, when an explosive aurora known as a breakup occurs, it sometimes leads to a flickering phenomenon. When an aurora flickers, its brightness and motion in some areas change rapidly. This flickering typically oscillates at a .1 second period, which is equivalent to the ion cyclotron frequency of oxygen ions.
