Why this forecast?
Five signals decide whether you'll see aurora from Lyon tonight. AuroraMe re-checks them every 15 minutes, and all five have to line up: even a strong storm stays invisible behind clouds or in a bright sky.
Aurora Zone
Higher magnetic latitude = better aurora visibility. Your location's magnetic latitude determines how often auroras appear overhead.
Status Levels:
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
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:
Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.
Status Levels:
Darkness
Darker skies are essential for aurora viewing. The sun must be below the horizon for auroras to be visible.
Status Levels:
Aurora Borealis Viewing in Lyon
Third largest city in France with potential for aurora during strong storms.
Lyon sits at 40.6° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 9+. Aurora sightings in Lyon require stronger geomagnetic storms (Kp 9+), 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.
For the broader storm picture before checking Lyon, start with the broader forecast hub and the geomagnetic storm tracker. Low-latitude places like Lyon usually need a severe geomagnetic storm, clear northern horizon, and full darkness before northern lights become realistic.

Based on its magnetic latitude of 40.6°, aurora viewing in Lyon is extremely rare (visible only during exceptional geomagnetic storms). Actual frequency varies with the 11-year solar cycle.
Best viewing season: September to March, with peak activity during equinoxes (September and March).
What Kp index do I need to see aurora in Lyon?
For Lyon, you need a minimum Kp index of 9.0 for aurora to be visible. This threshold is calculated based on the city's magnetic latitude (40.6°).
Higher Kp values produce brighter, more active displays:
- Kp 9.0+: Strong, colorful displays visible even with some light pollution
Where should I look for aurora in Lyon?
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 Lyon, aurora typically remains closer to the horizon, so elevated viewing locations help.
