ノルウェーでオーロラを観測する最高の時期
太陽活動周期25期オーロラ観測完全ガイド
太陽活動周期25期は2025年〜2026年にピークを迎え、この20年間で最も強力なオーロラ活動が期待されます。ノルウェーで最高のオーロラ体験をするため、いつ、どこで観測すべきか、その全てをご紹介します。
Why 2025-2026 is the best time in years
Solar Cycle 25 reached its solar maximum in late 2024, producing G3 and G4-class geomagnetic storms visible as far south as Scotland. In northern Norway, Kp-index 3 storms are sufficient for strong aurora displays — and we are seeing Kp 5-7 events multiple times per month.
The aurora season: September to March
The Northern Lights require two conditions: solar activity and a dark sky. Norway's aurora season runs from late September through late March, when nights are long enough for proper darkness. December and January offer the longest nights, but October and February often deliver clearer skies with less precipitation.
Best destinations in Norway
Tromsø at 70°N sits directly under the auroral oval — the ring of maximum aurora activity circling the magnetic pole. Svalbard offers unique opportunities for 24-hour darkness in winter. The Lofoten Islands combine dramatic scenery with excellent aurora viewing.
What to book
A guided Northern Lights chase from Tromsø costs €90-€180 per person and includes transport to clear-sky locations away from city light pollution. Private tours for groups of 4 run €350-€500 and are worth every krone for serious photographers.
