Space weather describes solar activity that can disrupt satellites and power grids, and produce aurora visible from East Derry under clear skies. Check the live forecast above for current solar wind conditions and aurora probability in your area.
How does space weather affect the UK?
Most space weather events are harmless to people on the ground, but strong geomagnetic storms can interfere with GPS signals, radio communications, and even cause voltage fluctuations in power networks. The Met Office’s space weather forecast monitors solar flares and coronal mass ejections (CMEs) that might reach Earth. For East Derry, the live forecast above shows the current Kp index, which indicates aurora visibility – a Kp of 5 or higher often means the Northern Lights could be seen from the north coast.
Will we see the Northern Lights tonight?
If the live forecast above shows elevated geomagnetic activity and skies are clear, head to a dark spot away from streetlights. The best chance for aurora in East Derry comes during stronger storms when the Kp index reaches 6 or more. You can also use a space weather app to get real-time alerts. For a longer outlook, check our 10 Day Weather Forecast UK for cloud cover predictions.
What is a geomagnetic storm?
A geomagnetic storm is a temporary disturbance of Earth’s magnetosphere caused by a solar wind shock wave or CME. It can trigger aurora and disrupt technology. The severity is measured by the Kp index.
Where can I get a space weather forecast for the UK?
The Met Office issues daily space weather forecasts for the UK, covering solar flare risk, geomagnetic storm alerts, and aurora visibility. NOAA also provides global space weather live data useful for planning.
Can space weather affect my mobile phone?
Direct effects on personal phones are very rare. Severe storms can disrupt satellite signals used by GPS and some mobile networks, but everyday calls and texts are generally unaffected.
