Tonight's Forecast

Low

How we calculate the aurora score

Low

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

With current Kp 2.3 (location needs ≥ 4) and 56% cloud cover, only a faint aurora is possible at Igiugig, and only under otherwise perfect conditions.

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.

Low chance tonight. Aurora may be possible only under very favorable local conditions.

Aurora Score 35 /100

Aurora visibility in Igiugig is low tonight. A stronger geomagnetic storm or better local conditions would improve the chance of seeing the Northern Lights.

With current Kp 2.3 (location needs ≥ 4) and 56% cloud cover, only a faint aurora is possible at Igiugig, and only under otherwise perfect conditions.

Direction to Look

Overhead or north

Min Kp 4 Lat 59.3°

Why this forecast?

There is a low chance of visible aurora tonight. Some conditions may help, but overall the forecast does not strongly support visibility.

Score breakdown

Aurora activity 23 / 100

Final score 35 / 100

Geomagnetic activity 2.3 / 4

Geomagnetic activity (Kp index)

Below threshold

Kp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Igiugig needs Kp ≥ 4.

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.

Below threshold

Geomagnetic activity is below the usual visibility threshold for Igiugig: expected Kp is 2.3, while this location usually needs around 4.

Cloud cover 79%

Cloud cover

Cloudy

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.

Cloudy

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

✓

Darkness astronomical

Sky darkness

Astronomical darkness

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.

Astronomical darkness

The sky reaches full astronomical darkness tonight — the sun more than 18° below the horizon, dark enough for even a faint aurora.

Moonlight 86%

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 86% illuminated — expect washed-out faint aurora.

•

Aurora oval probability 7%

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.

Moderate

The aurora oval probability is moderate for this location tonight, so activity may be close by if the sky is clear.

✓

Aurora zone Good zone

Aurora zone

Good zone

How favourable Igiugig'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.

Good zone

Igiugig is in a good aurora region, where aurora is possible during moderate geomagnetic activity.

Frequently Asked Questions

Can you see the Northern Lights in Igiugig tonight?

Some nights. At 58.2° geomagnetic latitude Igiugig sits outside the quiet oval, so it takes moderate activity — Kp 4 and above — to bring the ring within reach. Cloud and darkness decide the rest.

What Kp index is needed to see the Northern Lights in Igiugig?

Kp 4. The oval widens about 2° toward the equator with each step up the scale, and Igiugig is roughly 8° outside its quiet edge — which is why a single extra point changes what you see here.

What are the best months to see the Northern Lights in Igiugig?

September to April, with November to February giving the most hours of real darkness. The March and September equinoxes carry a statistical tilt toward higher activity — a shift in the odds, not a promise for any one night.

Where is the best place to see the Northern Lights in Igiugig?

You can watch from Igiugig itself. With this few lights around, a garden or the nearest open field is enough, provided nothing blocks the northern horizon. What matters more here is the moon: a bright one washes out faint aurora, so nights near new moon are the ones to pick.
