Why this forecast?
Aurora Zone
Higher magnetic latitude = better aurora visibility. Your location's magnetic latitude determines how often auroras appear overhead.
Status Levels:
Perfect Above 62.0° — Excellent aurora visibility (daily activity)
Good 56.0° - 62.0° — Good aurora visibility (regular storms)
Acceptable 50.0° - 56.0° — Fair aurora visibility (strong storms only)
Low Below 50.0° — Poor aurora visibility (extreme storms)
Aurora Zone
Perfect 63.2°
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
Storm Kp 6-9 — Geomagnetic storm, strong auroras
Active Kp 3-6 — Moderate activity, good conditions
Quiet Kp 1-3 — Low activity, weak auroras
Very Quiet Kp 0-1 — Very quiet, minimal auroras
Kp index
Active 3
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:
Clear Clear (0-25%) — Perfect for aurora viewing
Partly Cloudy Partly Cloudy (26-50%) — May partially block view
Cloudy Cloudy (51-85%) — Significantly blocks aurora
Overcast Overcast (85%+) — Blocks aurora completely
Cloud Cover Impact
☁️ Overcast 100%
Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.
Status Levels:
New Moon Darkest skies — Best for faint auroras
Crescent Dim moonlight — Good for viewing
Quarter Moderate moonlight — May wash out weak auroras
Gibbous Bright moonlight — Reduces aurora visibility
Full Moon Very bright — Only strong auroras visible

🌒 Crescent 8%
Darkness
Darker skies are essential for aurora viewing. The sun must be below the horizon for auroras to be visible.
Status Levels:
Night Darkest conditions — Optimal for auroras
Astronomical Twilight Dark enough — Good aurora viewing
Nautical Twilight Getting darker — Weak auroras may appear
Daylight Sun is above horizon — No aurora visible
