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.
