Northern lights in Willow
From Willow the aurora can show up on almost any clear, dark night — low to the north-north-east when activity is quiet, higher and overhead when it picks up. Since 1995 that level (Kp 4.7) was reached during darkness here on 691 nights.

How far ahead can the northern lights be forecast?
- Minutes to an hour: satellites 1.5 million km away measure the solar wind before it reaches Earth. This is the surest warning — the “Right now” box uses it.
- 1–3 days: when the Sun throws out a cloud of particles, it takes one to three days to arrive. NOAA's 3-hourly forecast covers these nights; the timing can still be off by a few hours.
- 4–27 days: the Sun turns once every 27 days, and regions that disturbed Earth's field last time often do it again. NOAA's 27-day outlook gives this rough trend — new eruptions are not in it yet.

The Kp scale in plain words
Kp is a 0–9 score for how strongly the Earth's magnetic field is being shaken by the solar wind. The higher it goes, the further from the poles the northern lights reach. Kp 0–2 is a quiet night; Kp 5 and above is a geomagnetic storm.
- Kp 0–2 Quiet next 24 h eye in Willow camera in Willow Only under the auroral oval: northern Norway, Swedish and Finnish Lapland, Iceland, Alaska, northern Canada.
- Kp 3 Unsettled Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
- Kp 4 Active Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
- Kp 5 Minor storm (G1) Scotland, southern Scandinavia, the Baltic states, the northern US states and southern Canada.
- Kp 6 Moderate storm (G2) Northern England, Denmark, northern Germany and Poland, the US Midwest — often clearer in photos than to the eye.
- Kp 7 Strong storm (G3) Most of the UK, the Netherlands, Germany, Poland, Czechia; red glow in photos from France and the northern Alps.
- Kp 8 Severe storm (G4) Central Europe to the eye; red sky in photos from northern Italy, Spain, the Balkans and Turkey's Black Sea coast.
- Kp 9 Extreme storm (G5) Seen across Europe and the US; in photos as far south as the Mediterranean, Turkey and North Africa (May 2024).
Light pollution
Pristine dark sky. Almost no artificial light: faint aurora and the Milky Way are easy to see.
Estimate from NASA VIIRS night-light data (sky-glow model within 50 km). Check access and private land before you go.
Hills and mountains
The horizon towards the north-north-east is open (terrain below 1.3°), so low aurora is not blocked.
From elevation data (AWS Terrain Tiles) along seven lines of sight up to 30 km.

Darkness through the year
- No full darkness (Sun 12° below the horizon) from 5 May to 8 August — the sky stays too bright for most auroras.
- Next new moon 8 November, next full moon 25 October. The darkest skies are in the week around new moon.

Questions and answers
What Kp do you need to see the aurora in Willow?
From Willow the aurora can show up on almost any clear, dark night — low to the north-north-east when activity is quiet, higher and overhead when it picks up.
Which way should I look for the aurora in Willow?
Face north-north-east (about 20° from true north). At Kp 0.3 the lower edge of the aurora sits roughly 16° above the horizon; stronger activity lifts it higher and further across the sky.

When is the aurora season in Willow?
From 5 May to 8 August the sky in Willow never gets dark enough. Outside that period the aurora can be seen whenever activity and clouds allow.
