Grid Magnetic Angle calculator

Something interesting is happening to the magnetic field in Great Britain this year. Find out what!

Try out our grid magnetic angle calculator to correct between magnetic bearings and map bearings.

Viewing the Northern Lights

Read our guide on how to see the Northern Lights from the UK.

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!
