Our review of the activities of the Geomagnetism Team in 2014 is now available to download.
A new magnetic observatory has been installed and commissioned in Canada. This joint five-year project between BGS and Halliburton Group Canada aims to improve the accuracy, safety and efficiency of directional drilling operations in northern Alberta. Find out more about Fort McMurray observatory.
A new paper has been published on the sensitivity of geomagnetically induced currents (GIC) to varying auroral electrojet and conductivity models. We investigate whether changing the conductivity of the ground makes a difference to the size of GIC generated during large geomagnetic storms.
What are geomagnetically induced currents? Find out more.
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!

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.
Modelling the Earth's magnetic field, space weather hazards.
About our magnetic observatory operations, UK surveying, equipment.
Observatory data, indices, models, charts, applications.
Overviews of the Earth's magnetic field, reversals, magnetic poles.
