Kp Index
Kp measures the disturbance of Earth's magnetic field on a scale of 0 to 9. From Iceland or Norway, Kp 3 already gives real chances. At Kp 5 or above the aurora becomes visible at even lower latitudes.
Bz (IMF)
The vertical direction of the solar magnetic field arriving at Earth. When it's negative (green), the solar and terrestrial fields couple and energy pours in. When it's positive (red), they repel.
--
Cloud Cover
Percentage of sky covered at your location over the next 6 hours. Below 30% the sky is clear enough. Above 70% the chance of seeing anything drops near zero.
Best Window
The time window where the forecasted Kp is highest over the next 24 hours. Each bar shows expected activity intensity.

Forecast Summary
Tonight's Outlook
Conditions tonight from Reykjavík are highly favorable. A G1 geomagnetic storm is forecast, with Kp expected to reach 5.0 — strong enough to produce auroras visible to the naked eye across all of Iceland. Solar wind speed is elevated and the Bz component is turning southward, coupling energy directly into Earth's magnetosphere.
Your optimal window opens at 22:45 and extends to 02:30 — 3h 45m of peak visibility. Cloud cover is minimal at 12%, temperatures around −3°C, and the waxing crescent moon (34% illuminated) leaves the sky dark all night. Head out after 22:30 and face north.
