Green & red
Oxygen produces familiar green and red auroral light. The colour depends on the emission and the conditions high above us.
SWEDISHAURORA03 / Your pocket field guide
Simple explanations and practical starting points, from your first glimpse of an arc to your first photograph of the lights.
Choose your season
Plan for dark nights and allow several evenings if you can. No month can guarantee a sighting; local weather can decide the whole trip.
Autumn can offer open-water reflections before the freeze and less severe cold than deep winter. Rain, cloud and slippery ground still matter. Check how late full darkness begins for your exact dates.
The wonder, explained
Energetic particles guided by Earth’s magnetic field collide with gases high in the atmosphere. Those gases release energy as light.
Oxygen produces familiar green and red auroral light. The colour depends on the emission and the conditions high above us.
Nitrogen contributes blue and purple light. Mixed emissions can give the lower edge of a bright curtain a pink appearance.
A faint display may look pale or grey. A camera can record more colour by collecting light over a longer exposure. Photographs and eyesight are different experiences.
An arc looks like a band across the sky. Folded rays can resemble a curtain. A corona appears to radiate from a point overhead: perspective makes the roughly parallel rays seem to converge.
Moonlight can reduce the contrast of faint aurora, but bright displays can still be visible. It can also illuminate the foreground in photographs. Cloud and local light pollution deserve attention too.
No. This far north, aurora can be visible without a major storm. Activity forecasts describe possibilities across a large region, not a guaranteed show at a particular time and place.
Bring home more than a memory
Use Night mode if your phone offers it. Turn off flash, support the phone on a tripod or stable surface, and use a timer. Tap a distant bright detail to focus; focus controls vary by phone.
These are starting points, not universal settings. Take a test photo, zoom in and adjust.
Comfort buys you time
Aurora watching is colder than an active walk. Keep a warm retreat close and return before anyone gets too cold.
Use this checklist for the current visit. Your selections are not saved.
The night is bigger than the aurora
Watch the stars and the northern horizon. Put the bright screen away for a while. Quiet spells are normal; keep checking without sacrificing warmth.
Try a night photograph of a familiar landscape from a maintained path. Avoid adding an unfamiliar gorge, icy shore or long drive just to rescue the evening.
Leave time for another chance at the lights. Make the daylight part of the adventure, too: a winter husky journey, or snowshoeing and ice fishing with Snow Dog Arctic Adventures.
