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 Farmers Loop 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
Dark rural sky. Little artificial light. Faint displays are visible once your eyes have adapted.
A noticeably darker area starts about 15 km to the north. Open in OpenStreetMap
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 terrain rises to about 7° above the horizon towards the north-north-east. That hides low aurora: here you need about Kp 0 instead of Kp 0. A hilltop, shore or open field with a clear view to the north-north-east helps.

Questions and answers
What Kp do you need to see the aurora in Farmers Loop?
Farmers Loop sits right under the auroral oval: on clear, dark nights the aurora is often overhead, even when activity is quiet. Clouds matter far more than the Kp number here.
Which way should I look for the aurora in Farmers Loop?
Face north-north-east (about 20° from true north). At Kp 0 the lower edge of the aurora sits roughly 35° above the horizon; stronger activity lifts it higher and further across the sky.
What is the best month to see the aurora in Farmers Loop?
Over 2005–2025, March gave the best odds in Farmers Loop (72% of nights dark, active enough and mostly clear), followed by January (71%).
