Tonight's Forecast

Unlikely

How we calculate the aurora score

Unlikely

We combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for Saariselkä (region: auroral_oval).

With current Kp 1.7 (location needs ≥ 2) and 94% cloud cover, aurora viewing is unlikely at Saariselkä.

Unlikely 0-19

Score 0–19. Conditions strongly limit aurora visibility.

Low 20-44

Score 20–44. A faint aurora is possible only under perfect conditions.

Moderate 45-64

Score 45–64. Aurora may be visible to alert observers in dark, clear skies.

High 65-84

Score 65–84. A good chance of a visible aurora display.

Very High 85-100

Score 85–100. Excellent odds — plan to be outside tonight.

Aurora viewing is unlikely tonight.

Aurora Score 3 /100

Aurora visibility in Saariselkä is unlikely tonight. Current conditions do not strongly support visible Northern Lights.

With current Kp 1.7 (location needs ≥ 2) and 94% cloud cover, aurora viewing is unlikely at Saariselkä.

•

Geomagnetic activity 1.7 / 2

Geomagnetic activity (Kp index)

Near threshold

Kp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Saariselkä needs Kp ≥ 2.

Below threshold

Kp is below the minimum needed at this latitude.

Near threshold

Kp is close to the minimum needed — a faint aurora may appear low on the horizon.

Enough for this location

Kp meets the threshold for visible aurora here.

Strong for this location

Kp is comfortably above the local threshold.

Geomagnetic storm

Storm-level Kp ≥ 5 — aurora can be seen far south of its usual zone.

Near threshold

Geomagnetic activity is only marginal for Saariselkä: expected Kp is 1.7, while this location usually needs around 2.

Cloud cover 97%

Cloud cover

Overcast

Average cloud cover during the best viewing window. Clear skies are essential — even thin overcast hides the aurora.

Clear skies

Up to 25% cloud — excellent visibility.

Partly cloudy

25–50% cloud — aurora may peek through gaps.

Cloudy

50–85% cloud — most of the sky is blocked.

Overcast

Over 85% cloud — aurora effectively hidden.

Overcast

Cloud cover is high tonight, which can block the view even if aurora activity is present.

Darkness Civil twilight

Sky darkness

Civil twilight

Aurora is faint and needs a dark sky. Astronomical darkness (sun more than 18° below horizon) is ideal.

No dark window

Sun stays above 6° below horizon all night — no aurora-friendly darkness.

Civil twilight

Sun 6–12° below horizon — too bright for faint aurora.

Nautical twilight

Sun 12–18° below horizon — sky is dark but not fully astronomical.

Astronomical darkness

Sun more than 18° below the horizon — fully dark sky.

Civil twilight

There is only civil twilight tonight. The sky may still be too bright for faint aurora, although stronger displays could still be visible.

Moonlight 80%

Moon illumination

Bright moon

A bright moon washes out faint aurora colours. New moon is ideal; full moon hides everything but the strongest displays.

Dark moon

Less than 25% illuminated — minimal interference.

Moderate moonlight

25–75% illuminated — faint aurora may be washed out.

Bright moon

Over 75% illuminated — only strong displays will be visible.

Bright moon

Moon is 80% illuminated — expect washed-out faint aurora.

•

Aurora oval probability 5%

Aurora oval probability (OVATION)

Moderate

NOAA's OVATION model estimates the chance of aurora visible overhead within a 250 km radius of you.

Low

Less than 5% probability — aurora unlikely to reach this location.

Moderate

5–20% probability — aurora possible.

Elevated

20–40% probability — aurora likely if skies are clear.

High

Over 40% probability — aurora very likely overhead.

Aurora zone Excellent zone

Aurora zone

Excellent zone

How favourable Saariselkä's latitude is for aurora viewing in general — independent of tonight's conditions.

Low zone

Lower latitude — aurora is rare and requires a major storm.

Fair zone

Mid-latitude — aurora visible only during moderate-to-strong storms.

Good zone

High-latitude region — aurora is visible on most active nights.

Excellent zone

Directly under the auroral oval — aurora is a regular occurrence.

Excellent zone

Saariselkä is in a prime aurora zone, so aurora can be visible during regular activity when skies are dark and clear.
