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.

  1. Kp 0–2 Quiet Only under the auroral oval: northern Norway, Swedish and Finnish Lapland, Iceland, Alaska, northern Canada.
  2. Kp 3 Unsettled camera in Viborg Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
  3. Kp 4 Active next 24 h Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
  4. Kp 5 Minor storm (G1) eye in Viborg Scotland, southern Scandinavia, the Baltic states, the northern US states and southern Canada.
  5. Kp 6 Moderate storm (G2) Northern England, Denmark, northern Germany and Poland, the US Midwest — often clearer in photos than to the eye.
  6. Kp 7 Strong storm (G3) Most of the UK, the Netherlands, Germany, Poland, Czechia; red glow in photos from France and the northern Alps.
  7. 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.
  8. 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

City sky. City lights hide all but the brightest displays. Plan to leave the urban area.

A noticeably darker area starts about 5 km to the west-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 0.0°), so low aurora is not blocked.

From elevation data (AWS Terrain Tiles) along seven lines of sight up to 30 km.

Over 2005–2025, September gave the best odds in Viborg (6% of nights dark, active enough and mostly clear), followed by March (5%).

When is the aurora season in Viborg?

From 26 May to 18 July the sky in Viborg never gets dark enough. Outside that period the aurora can be seen whenever activity and clouds allow.
