Can you see the northern lights in Stockton Springs?
From Stockton Springs the aurora is seen only during geomagnetic storms (about Kp 5.3 or more), usually as a glow low in the north-north-west. Cameras often pick it up before the eye does. Since 1995 that level (Kp 5.3) was reached during darkness here on 476 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 Only under the auroral oval: northern Norway, Swedish and Finnish Lapland, Iceland, Alaska, northern Canada.
- Kp 3 Unsettled next 24 h Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
- Kp 4 Active camera in Stockton Springs Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
- Kp 5 Minor storm (G1) eye in Stockton Springs 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 terrain rises to about 4° above the horizon towards the north-north-west. That hides low aurora: here you need about Kp 5.3 instead of Kp 5.3. A hilltop, shore or open field with a clear view to the north-north-west helps.
