How we calculate the aurora score
LowWe combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for Bad Neuenahr-Ahrweiler (region: low_latitude).
With current Kp 5.0 (location needs ≥ 6) and 25% cloud cover, only a faint aurora is possible at Bad Neuenahr-Ahrweiler, and only under otherwise perfect conditions.
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.
Low chance tonight. Aurora may be possible only under very favorable local conditions.
Skies may be clear in Bad Neuenahr-Ahrweiler, but aurora activity is currently too weak for a good viewing chance.
With current Kp 5.0 (location needs ≥ 6) and 25% cloud cover, only a faint aurora is possible at Bad Neuenahr-Ahrweiler, and only under otherwise perfect conditions.

Best Viewing Window
12:00 AM – 2:00 AM
Best balance of darkness, geomagnetic activity and local sky conditions.
Direction to Look
North
This location is farther from the auroral oval, so aurora is most likely to appear low on the northern horizon during strong activity.
Recommendation
Check the forecast again later. Aurora conditions can change quickly during geomagnetic activity.

Geomagnetic activity (Kp index)
Near thresholdKp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Bad Neuenahr-Ahrweiler needs Kp ≥ 6.
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.
Near threshold
Geomagnetic activity is close to the threshold for Bad Neuenahr-Ahrweiler: expected Kp is 5.0, and this location usually needs around 6. A faint aurora low on the horizon is possible.
?
Cloud cover
Clear skiesAverage 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.
Clear skies
Skies are mostly clear, which is favorable for seeing the aurora.
?
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)
LowNOAA'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.
Low
The aurora oval probability is low for this location tonight.
?
Aurora zone
Low zoneHow favourable Bad Neuenahr-Ahrweiler'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.
Low zone
Bad Neuenahr-Ahrweiler is outside the main aurora zone, so visible aurora usually requires a strong geomagnetic storm.

Frequently Asked Questions
Can you see the Northern Lights in Bad Neuenahr-Ahrweiler tonight?
Rarely. Bad Neuenahr-Ahrweiler is far enough from the pole that it takes Kp 6 or more, storm levels, before the ring stretches this far. When it does, expect a faint glow low on the northern horizon rather than anything overhead — and a clear sky, or none of it matters.
What Kp index is needed to see the Northern Lights in Bad Neuenahr-Ahrweiler?
Aurora is rare this far from the pole. Bad Neuenahr-Ahrweiler sits at 46.5° geomagnetic latitude, about 20° south of the quiet oval, and needs Kp 6 or more before the ring stretches far enough — storm levels, not an ordinary night. When it does happen it is usually a faint glow low in the north, often clearer in a photograph than to the eye.
What are the best months to see the Northern Lights in Bad Neuenahr-Ahrweiler?
The best months to see the Northern Lights in Bad Neuenahr-Ahrweiler are typically September to April, when nights are darker and aurora viewing conditions are better.
Where is the best place to see the Northern Lights in Bad Neuenahr-Ahrweiler?
