1. What is the Kp-Index and from which value can I see Northern Lights in Germany?
The Kp-index measures global geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm). In Germany (e.g., Berlin, Hamburg, Munich), Northern Lights are usually visible from Kp 5-6 – often low on the northern horizon and faint. From Kp 7+ (G3 storm or higher), chances increase significantly: The lights can be brighter, higher in the sky, and even visible in southern Germany. Check the current Kp live on auroramap.de – perfect for spontaneous hunts!
2. How important are solar wind speed and Bz value for Northern Lights?
Very important! Faster solar wind (>500–800 km/s, often from CMEs) brings more energy into the magnetosphere. The IMF Bz value is the "key": Negative (southward, e.g., -10 nT or lower) opens the magnetosphere like a door – the more negative, the more intense the Northern Lights. High proton density (>10–20 p/cm³) enhances it further. Combine these values on our live map for the best forecast.
3. Why do Northern Lights glow in green, violet, or red?
The colors arise from charged particles colliding with atmospheric gases:
• Green (most common): Oxygen at 100–240 km altitude.
• Violet/Pink: Nitrogen at lower layers (~100 km).
• Rare Red: Oxygen at high altitudes (>300 km) during strong storms – visible even in Central Europe.
Strong storms (Kp 7+) often bring colorful mixes!
4. When is the best time to see Northern Lights in Germany or Europe (2026)?
2026 is a top year – we're near the solar maximum aftermath with high activity! The season runs from September to March (long dark nights). Best months: September/October and February/March due to geomagnetically active equinox times. Best time: 9 PM–2 AM, often peaking around midnight. Check auroramap.de for clear nights and high Kp/Bz values – even at Kp 5-6, it can work in northern Germany!
5. How do I photograph Northern Lights best – even with a smartphone?
Use a tripod (essential!), wide-angle lens (14–24 mm, f/1.4–2.8) and manual settings:
• ISO: 800 to 3200 (start at 1600 to 3200).
• Shutter: 3–25 seconds (shorter for fast movements, longer for faint lights).
• Focus: Manual to infinity (live view on a star to sharpen).
For smartphones: Night mode or Pro mode with tripod – 10–20 s, ISO 800+. Shoot RAW, edit later (contrast, white balance ~3500–4500 K). Avoid overexposure – check histogram! More tips on our site.
6. Can I predict Northern Lights? How reliable is auroramap.de?
Yes – but 100% certainty isn't possible (clouds, local conditions play a role). Our data comes directly from NOAA SWPC: Real-time Kp, solar wind, Bz, proton density. We show probabilities for selected cities and archives of past events. Combine with weather apps for clear nights – maximize your chances!
7. Why do I sometimes see Northern Lights even if Kp is low?
Kp is global – local/regional activity can be stronger. Negative Bz + high solar wind can bring strong Northern Lights even at medium Kp. In Germany, often look north (unobstructed horizon, dark location). Our live data shows you the exact status!
8. Are there Northern Lights in summer too?
Technically yes (with strong activity), but in summer there's too little darkness north of the Arctic Circle. In Germany, the season is limited to September–March. 2026 remains exciting into spring!
