Why this forecast?
Five signals decide whether you'll see aurora from Upper Kalskag 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:
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
Good 59.8°
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 5.3
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
Clear 15%
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
Moonlight
Crescent 14%
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

Northern Lights in Upper Kalskag: Quick Guide
How often can you see northern lights in Upper Kalskag?
Based on its magnetic latitude of 59.8°, aurora viewing in Upper Kalskag is occasional (10-40 nights per year). Actual frequency varies with the 11-year solar cycle.

What Kp index do I need to see aurora in Upper Kalskag?
