Sign-up for geomagnetic disturbance alerts

When we predict an increase in magnetic activity we send out a geomagnetic disturbance alert.
Notice of a potential magnetic storm increases your chance of seeing the Northern Lights!

Sign up for alerts by email or Twitter.

About BGS Geomagnetism

The Geomagnetism team measures, records, models and interprets variations in the Earth’s natural magnetic fields.

Our data and expertise help to develop scientific understanding of change in the Earth and the environment, from deep within the core out into space.

We also provide geomagnetic products and services to industry and to academic colleagues and we use our knowledge for information and education.

Research

Modelling the Earth's magnetic field, space weather hazards.

Operations

About our magnetic observatory operations, UK surveying, equipment.

Data and Services

Observatory data, indices, models, charts, applications.

Education

Overviews of the Earth's magnetic field, reversals, magnetic poles.
