Typical-year figures: a 1996–2026 planetary Kp record crossed with a 2001–2020 cloud normal. They describe a normal year, not tonight — the live Ny-Ålesund forecast shows the actual cloud, moon and darkness right now. Check tonight's forecast for Ny-Ålesund →

April, May, June, July, August and September never reach astronomical darkness at Ny-Ålesund, so no Kp value makes them viewing months and they are excluded rather than scored.
Opportunity nights are the whole 1996–2026 record. In the current solar cycle alone (since 2023), January has averaged 32.03 rather than 28.48.
- January: 13.56h of astronomical darkness a night
- January: 28.48 nights reach the Kp threshold inside that darkness
- January: 84.7% mean cloud leaves 4.36 of them clear
- January: 53.4% of those nights are moon-free

How these numbers were made
- Evaluated at
- Ny-Ålesund, 78.9249° N 11.9308° E — darkness and cloud are properties of that point, not of a region.
- Darkness
- Sun at or below 18° under the horizon (astronomical twilight), sampled every 10 minutes across every year of the Kp record and averaged per night of each month rather than on one representative day.
- Geomagnetic record
- GFZ Potsdam planetary Kp index, 3-hourly, 1996–2026 — 89,662 intervals, licensed CC BY 4.0.
- Cloud
- NASA POWER 20-year monthly climatology (2001–2020), parameter CLOUD_AMT. A monthly mean, not a forecast.
- Moon
- A night counts as moon-free below 35% lunar illumination while the moon is up.
- Auroral oval
- NOAA auroral-oval model, equatorward boundary near magnetic latitude 67 − 2 × Kp. A model estimate shown beside the measured record; it never replaces it.
- Clear opportunity nights
- Nights on which at least one 3-hour Kp interval falls inside local astronomical darkness and reaches the count threshold, scaled by one minus the monthly mean cloud amount.
- Kp threshold
- Nights were counted at Kp 1 or higher, the same threshold the live forecast serves.

Frequently Asked Questions
When can you see the northern lights in Ny-Ålesund?
January is the best month, with 4.36 clear nights in a typical year out of 19 across the whole year. The months with any chance at all are January, February, March, October, November and December. April, May, June, July, August and September never reach astronomical darkness, so no Kp value makes them viewing months.
What Kp is needed to see the aurora from Ny-Ålesund?
Ny-Ålesund needs Kp 1 or higher for aurora, Kp 2 for a noticeable display and Kp 3 for a bright one. The NOAA auroral-oval model places the oval overhead at Ny-Ålesund once the planetary index reaches Kp 1. That is a model estimate; the dates on this page come from the measured Kp record instead.
Has the aurora ever been visible from Ny-Ålesund?
Yes. In the 1996–2026 planetary Kp record the index reached Kp 1, the threshold these nights were counted at for Ny-Ålesund, most recently on 1 March 2026. The Kp 2 needed for a noticeable display was last reached on 28 February 2026. Whether anyone saw it also depended on the cloud, moonlight and darkness of that night, which the Kp record does not carry.
