What affects visibility
Aurora Zone
Higher magnetic latitude = better aurora visibility. Your location's magnetic latitude determines how often auroras appear overhead.
Status Levels:
PerfectAbove 62.0° - Excellent aurora visibility (daily activity)
Good56.0° - 62.0° - Good aurora visibility (regular storms)
Acceptable50.0° - 56.0° - Fair aurora visibility (strong storms only)
LowBelow 50.0° - Poor aurora visibility (extreme storms)
Aurora Zone
Acceptable 51.6°
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
StormKp 6-9 - Geomagnetic storm, strong auroras
GoodKp 3-6 - Moderate activity, good conditions
LowKp 1-3 - Low activity, weak auroras
Very QuietKp 0-1 - Very quiet, minimal auroras
Kp index
Very Quiet 0.7
Cloud Cover Impact
Clear skies are essential for aurora viewing. Clouds block your view of the northern lights. The percentage shows cloud coverage (0% = clear skies, 100% = overcast).
Status Levels:
ClearClear (0-25%) - Perfect for aurora viewing
Partly CloudyPartly Cloudy (26-50%) - May partially block view
CloudyCloudy (51-85%) - Significantly blocks aurora
OvercastOvercast (85%+) - Blocks aurora completely
Cloud Cover Impact

Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.
Status Levels:

CrescentDim moonlight - Good for viewing
QuarterModerate moonlight - May wash out weak auroras
GibbousBright moonlight - Reduces aurora visibility
Full MoonVery bright - Only strong auroras visible

Aurora Borealis Viewing in Horsens
Horsens sits at 51.6° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 7+. Aurora sightings in Horsens require stronger geomagnetic storms (Kp 7+), which occur a few times per year. When storms do hit, the best viewing window is 10 PM to 2 AM local time under clear, dark skies.
Cloud cover is the most common reason people miss aurora even during strong storms. AuroraMe combines the Kp index with real-time cloud forecasts, moon phase, and darkness data to give you a single visibility status — so you know whether it's worth going outside tonight.

How often can you see northern lights in Horsens?
Based on its magnetic latitude of <strong>51.6°</strong>, aurora viewing in Horsens is <strong>rare (5-15 nights per year, mainly during strong storms)</strong>. We are currently near solar maximum (2024-2025), so expect higher-than-average activity.
Best viewing season: September to March, with peak activity during equinoxes (September and March).
What Kp index do I need to see aurora in Horsens?
For Horsens, you need a minimum Kp index of <strong>6.0</strong> for aurora to be visible. This threshold is calculated based on the city's magnetic latitude (51.6°).
Higher Kp values produce brighter, more active displays:
- Kp 6.0-7.0: Faint aurora visible in dark skies
- Kp 7.0-8.0: Moderate aurora with dancing patterns
- Kp 8.0+: Strong, colorful displays visible even with some light pollution
Current Kp index: 0.7
Where should I look for aurora in Horsens?
Aurora is rarely visible this far south. When it does appear during extreme storms (Kp 7+), look for a faint glow on the northern horizon.
For best results, seek locations with minimal light pollution and unobstructed views of the sky. From Horsens, aurora typically remains closer to the horizon, so elevated viewing locations help.
Can I see northern lights tonight in Horsens?
Unlikely: Aurora unlikely tonight with Kp 0.7 (below 6.0 threshold for Horsens). Enable alerts to catch future opportunities.
Real-time conditions: 99% cloud cover, aurora probability 0%. Check the live forecast above for the latest updates.
