The aurora shimmers across Arctic skies year-round, but Norway’s prime viewing season is from September to March when the nights are dark enough. During this period, the best viewing hours are between 5 p.m. and 2 a.m. Aurora displays can be brief, lasting a few minutes, or stretch out for 15 to 30 minutes, and on lucky nights, even a couple of hours.
There’s a higher chance of vibrant displays near the equinoxes in late September and March. This phenomenon, partly due to the Russell-McPherron effect, involves an alignment of Earth’s and the solar wind’s magnetic fields, creating favorable conditions for geomagnetic storms.
