Northern Lights in County Donegal on 2 September 2025

The Aurora Borealis lit up the skies across north Ulster on Monday night into Tuesday morning, thanks to partial clearing of cloud cover.

The video below, captured at Fort Dunree near Buncrana on County Donegal’s Inishowen Peninsula, features footage from a YouTube livestream hosted by Adam Porter Photography.

The National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center had earlier issued a geomagnetic storm watch, warning of potential aurora displays.

NOAA explained that the storm had been caused by a “symmetric full-halo Coronal Mass Ejection (CME)”, an eruption of solar material and magnetic fields from the Sun.
