Geomagnetic Storm Forecasts
We examine solar activity daily and forecast if this is likely to have any geomagnetic effect on Earth.
If this 'space weather' indicates that a large magnetic storm is possible in the next few days we may send out a geomagnetic storm forecast.
You can keep an eye on the current geomagnetic activity levels for yourself.
You can sign-up to receive a Geomagnetic Storm Forecast email or follow us on Twitter to get daily space weather forecasts or occasional aurora alerts.
