Why this forecast?
Five signals decide whether you'll see aurora from Kilkenny 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
Low 49.4°
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
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
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

Aurora Borealis Viewing in Kilkenny
Medieval city with moderate aurora potential.
Kilkenny sits at 49.4° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 8+. Aurora sightings in Kilkenny require stronger geomagnetic storms (Kp 8+), 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 Kilkenny, start with the broader forecast hub and the geomagnetic storm tracker. Low-latitude places like Kilkenny usually need a severe geomagnetic storm, clear northern horizon, and full darkness before northern lights become realistic.

Northern Lights in Kilkenny: Quick Guide
How often can you see northern lights in Kilkenny?
Based on its magnetic latitude of 49.4°, aurora viewing in Kilkenny is very rare (1-5 nights per year during major 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 Kilkenny?
For Kilkenny, you need a minimum Kp index of 8.0 for aurora to be visible. This threshold is calculated based on the city's magnetic latitude (49.4°).
Higher Kp values produce brighter, more active displays:
- Kp 8.0-9.0: Faint aurora visible in dark skies
- Kp 9.0+: Strong, colorful displays visible even with some light pollution
Where should I look for aurora in Kilkenny?
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 Kilkenny, aurora typically remains closer to the horizon, so elevated viewing locations help.
Can I see northern lights tonight in Kilkenny?
Unlikely: Aurora unlikely tonight with Kp 5.3 (below 8.0 threshold for Kilkenny). Enable alerts to catch future opportunities.
