Photographs show different viewpoints, dates and conditions. They do not establish current access to a particular route. Every image is credited below.
The Northern Lights belong to a combination of solar activity, darkness, cloud and a suitable viewpoint. Their changing form matters as much as their brightness. Photographs may show colour differently from the unaided eye, so the experience is best approached with curiosity rather than a promise of a particular image.
Allow several possible observing nights in a practical base. Use current forecasts as one input, alongside cloud, access and the ability to return safely.
