Northern lights in Harbor Beach
Harbor Beach needs an active night: from about Kp 4.7 the aurora appears low over the north horizon, and it rises higher as activity grows. Since 1995 that level (Kp 4.7) was reached during darkness here on 955 nights.
Right now
It is still light here. Darkness starts at 19:39.

Maybe — worth a look
- Solar activity Strong enough: Kp 4.7 expected, 4.7 needed here.
- Sky Mostly clear (26% cloud).
- Darkness Dark from 19:39 to 06:51. A bright moon (80%) washes out faint displays.
What to do: Go somewhere dark around 19:00, give your eyes 15 minutes to adjust and look north, low over the horizon.

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.

Cloud layers and weather
Low cloud blocks the aurora completely. Thin high cloud often still lets a bright aurora shine through, so a sky with only high cloud is worth a look.

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 camera in Harbor Beach 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) next 24 h eye in Harbor Beach 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
Rural to suburban. Some sky glow from nearby lights. Moderate displays are fine; faint ones are easier a few kilometres out.
A noticeably darker area starts about 5 km to the east-south-east. 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 horizon towards the north is open (terrain below 0.1°), so low aurora is not blocked.
From elevation data (AWS Terrain Tiles) along seven lines of sight up to 30 km.
