How we calculate the aurora score
ModerateWe combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for Nikolai (region: high_latitude).
With current Kp 4.7 (location needs ≥ 3) and 98% cloud cover, aurora may be visible at Nikolai from a dark spot, once your eyes have adjusted.
Score 0–19. Conditions strongly limit aurora visibility.
Score 20–44. A faint aurora is possible only under perfect conditions.
Score 45–64. Aurora may be visible to alert observers in dark, clear skies.
Score 65–84. A good chance of a visible aurora display.
Score 85–100. Excellent odds — plan to be outside tonight.
Moderate chance tonight. Aurora may be visible from a dark spot if the sky stays clear.
Aurora activity may be favorable near Nikolai, but cloud cover could make the Northern Lights difficult or impossible to see.
With current Kp 4.7 (location needs ≥ 3) and 98% cloud cover, aurora may be visible at Nikolai from a dark spot, once your eyes have adjusted.

Direction to Look
Overhead or north
This is a high-latitude location, so aurora may appear overhead or toward the northern sky.
Recommendation
Cloud cover is the main problem tonight. Wait for breaks in the clouds before going out.

Why this forecast?
There is a moderate chance of visible aurora tonight. Some conditions are favorable, but clouds, moonlight or geomagnetic activity may still limit visibility.
Score breakdown
How tonight's aurora score for Nikolai breaks down into activity and visibility components.
?
Geomagnetic activity
30 / 30Geomagnetic activity (Kp 4.7) contribution to the score.

Aurora oval probability
10 / 30OVATION aurora oval probability (13%) contribution.

Darkness
15 / 15Sky darkness contribution — astronomical darkness scores full points.

?
Geomagnetic activity (Kp index)
Enough for this locationKp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Nikolai needs Kp ≥ 3.
Kp is below the minimum needed at this latitude.
Kp is close to the minimum needed — a faint aurora may appear low on the horizon.
Kp meets the threshold for visible aurora here.
Kp is comfortably above the local threshold.
Storm-level Kp ≥ 5 — aurora can be seen far south of its usual zone.
Enough for this location
Expected Kp 4.7 reaches the 3 that Nikolai usually needs, so activity is not what limits the night — cloud, darkness and the moon decide the rest.
?
Cloud cover
OvercastAverage cloud cover during the best viewing window. Clear skies are essential — even thin overcast hides the aurora.
Up to 25% cloud — excellent visibility.
25–50% cloud — aurora may peek through gaps.
50–85% cloud — most of the sky is blocked.
Over 85% cloud — aurora effectively hidden.
Overcast
Cloud cover is high tonight, which can block the view even if aurora activity is present.
?
Sky darkness
Astronomical darknessAurora is faint and needs a dark sky. Astronomical darkness (sun more than 18° below horizon) is ideal.
Sun stays above 6° below horizon all night — no aurora-friendly darkness.
Sun 6–12° below horizon — too bright for faint aurora.
Sun 12–18° below horizon — sky is dark but not fully astronomical.
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.
?
Moon illumination
Bright moonA bright moon washes out faint aurora colours. New moon is ideal; full moon hides everything but the strongest displays.
Less than 25% illuminated — minimal interference.
25–75% illuminated — faint aurora may be washed out.
Over 75% illuminated — only strong displays will be visible.
Bright moon
Moon is 77% illuminated — expect washed-out faint aurora.
?
Aurora oval probability (OVATION)
ModerateNOAA's OVATION model estimates the chance of aurora visible overhead within a 250 km radius of you.
Less than 5% probability — aurora unlikely to reach this location.
5–20% probability — aurora possible.
20–40% probability — aurora likely if skies are clear.
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 zoneHow favourable Nikolai's latitude is for aurora viewing in general — independent of tonight's conditions.
Lower latitude — aurora is rare and requires a major storm.
Mid-latitude — aurora visible only during moderate-to-strong storms.
High-latitude region — aurora is visible on most active nights.
Directly under the auroral oval — aurora is a regular occurrence.
Good zone
Nikolai is in a good aurora region, where aurora is possible during moderate geomagnetic activity.

Frequently Asked Questions
Can you see the Northern Lights in Nikolai tonight?
Some nights. At 61.6° geomagnetic latitude Nikolai sits outside the quiet oval, so it takes moderate activity — Kp 3 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 Nikolai?
Kp 3. The oval widens about 2° toward the equator with each step up the scale, and Nikolai is roughly 4° 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 Nikolai?
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 Nikolai?
You can watch from Nikolai 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.
