Space Weather Alerts

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 space weather alert.

A large magnetic storm increases the possibility of aurora being visible at mid-latitudes.

You can sign-up to receive a Geomagnetic Disturbance Alert email or follow us on Twitter to get daily space weather forecasts or occasional aurora alerts.
