Northern lights in Huron
Huron 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 924 nights.
Right now
It is still light here. Darkness starts at 19:49.
Latest measured half-hour activity worldwide: Hp30 1.3.

Tonight in one minute
Only in photos, if at all
- Solar activity Enough for a camera: Kp 4 expected, 3 needed for photos, 4.7 for the eye.
- Sky Mostly clear (0% cloud).
- Darkness Dark from 19:49 to 06:47.
What to do: Point a phone in night mode north (3–10 s exposure). A red or green glow often shows on the screen before you can see it.

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 Huron Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
- Kp 4 Active next 24 h Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
- Kp 5 Minor storm (G1) eye in Huron 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
Bright suburban sky. Strong sky glow washes out faint aurora. Head out of town for anything but a bright display.
A noticeably darker area starts about 5 km to the north-west. 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.

Questions and answers
What Kp do you need to see the aurora in Huron?
Huron needs an active night: from about Kp 4.7 the aurora appears low over the north horizon, and it rises higher as activity grows.
Which way should I look for the aurora in Huron?
Face north (about 6° from true north). At Kp 4.7 the lower edge of the aurora sits roughly 15° above the horizon; stronger activity lifts it higher and further across the sky.
What is the best month to see the aurora in Huron?
Over 2005–2025, September gave the best odds in Huron (7% of nights dark, active enough and mostly clear), followed by October (5%).
When is the aurora season in Huron?
Huron gets dark enough for the aurora all year round, though the long winter nights give the most hours to watch.
Is there much light pollution in Huron?
Strong sky glow washes out faint aurora. Head out of town for anything but a bright display. A noticeably darker area starts about 5 km to the north-west.
When was the aurora last possible in Huron?
The most recent night in our data when activity reached the level Huron needs, during darkness, was 4 October 2026 (Kp 5.0). It has happened on 924 nights since 1995.
