Auroras can last anywhere from a few minutes to several hours, with typical displays often in the 15–30 minute range, though longer bursts are possible during strong solar activity or substorms. The exact duration depends on solar wind intensity, geomagnetic conditions, and local viewing factors like cloud cover and light pollution. A single display can be short and flickering, or it can persist with intermittent intensifications for hours if the solar input remains strong. For the best chance of a longer show, look for periods of heightened geomagnetic activity and clear, dark skies around your local peak aurora season.
