Watch the northern lights live from Grindavík as a moderate geomagnetic storm (G2) arrives tonight. After quiet conditions over the past 24 hours, geomagnetic activity is forecast to surge dramatically, with Kp values climbing as high as 6.0 as a coronal hole high-speed solar wind stream (CH HSS) impacts Earth’s magnetic field.
This setup creates strong potential for bright, dynamic auroras across Iceland, especially during peak overnight hours. As the storm intensifies, the auroral oval expands and becomes more energetic, increasing the likelihood of vivid displays overhead.
Aurora outlook tonight:
• Expected intensity: G2 (moderate geomagnetic storm)
• Peak windows: Late evening through the overnight hours as Kp rises to ~6
• What to watch for: Bright green arcs, fast-moving curtains, vertical rays, and possible red hues during stronger pulses
• Why it’s happening: High-speed solar wind flowing from a coronal hole is energizing Earth’s magnetosphere
Space weather context:
• Activity builds rapidly from quiet to storm levels tonight
• No solar radiation storms are expected
• Minor radio blackout chances remain low
Weather note: With clear or partly clear skies, this storm could produce highly visible and fast-moving auroras over the volcanic landscapes of southwest Iceland. Grindavík offers a wide northern horizon—ideal for capturing large-scale auroral movement.
Join us live as the northern lights surge over Iceland during what could be one of the stronger aurora nights of the month.
