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
Low 20.7°
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
☁️ Cloudy
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 Australis Viewing in Salvador
Salvador sits at 20.7° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 9+. Aurora sightings in Salvador 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.
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 Salvador?
Based on its magnetic latitude of <strong>20.7°</strong>, aurora viewing in Salvador is <strong>extremely rare (visible only during exceptional geomagnetic storms)</strong>. We are currently near solar maximum (2024-2025), so expect higher-than-average activity.
Best viewing season: March to September, with peak activity during equinoxes (March and September).
What Kp index do I need to see aurora in Salvador?
For Salvador, you need a minimum Kp index of <strong>8.0</strong> for aurora to be visible. This threshold is calculated based on the city's magnetic latitude (20.7°).
Higher Kp values produce brighter, more active displays:
- Kp 8.0-9.0: Faint aurora visible in dark skies
- Kp 9.0-10.0: Moderate aurora with dancing patterns
- Kp 10.0+: Strong, colorful displays visible even with some light pollution
Current Kp index: 0.7
Where should I look for aurora in Salvador?
Watch the southern horizon for aurora during strong geomagnetic storms.
For best results, seek locations with minimal light pollution and unobstructed views of the sky. From Salvador, aurora typically remains closer to the horizon, so elevated viewing locations help.
