Seeing the northern lights from Copenhagen
Copenhagen sits at 55.4° magnetic latitude, just south of the usual auroral oval. A Kp of about 3.2 brings aurora into view low on the northern horizon, and about 5.5 puts it overhead.
Dark hours by month
Hours each night with the sun at least 12° below the horizon, on the 15th of each month.
The dark-sky season runs from August to April. From June the sky never gets fully dark, so aurora is effectively out of sight. Geomagnetic activity also tends to run higher around the March and September equinoxes.
What each storm level means here
The higher the Kp index, the farther the oval spreads toward the equator.
- Kp 9G5 extreme storm: aurora overhead from Copenhagen
- Kp 7G3 strong storm: aurora overhead from Copenhagen
- Kp 5G1 minor storm: aurora on the horizon from Copenhagen
- Kp 3Unsettled: aurora not in view from Copenhagen
