Field notes & historical context
The most accessible southern-lights base. Storms are required more often than in Tromsø.
Auroral ovals sit near 65°–70° geomagnetic latitude on quiet nights (Kp 2–3) and expand equatorward during geomagnetic storms (Kp 5+). Nautical darkness and clear skies are required.

Safety & responsible visiting
Sub-arctic and polar night viewing involves extreme cold, icy roads, and limited cell coverage. Never stop on unlit highway shoulders; use designated dark-sky pullouts and carry winter emergency gear.
Natural phenomena depend on live weather, local access rules, and habitat conditions. Verify local advisories before travelling.
