SAGE Variometer Data

In 2022, the SAGE BGS team installed three new variometers to measure magnetic field variation across the UK, filling in the 'gaps' between existing observatories. These cover an east-west line compared to the north-south coverage offered by the existing UK observatories. These new variometers are based on the design of the SWIGS differential magnetometer systems.

Below are plots of the magnetic field variations at the three sites for yesterday and today. Please note that these are variation data and the values presented may not reflect the true full-field magnetic field values.

Variometer Code Latitude (Deg) Longitude (Deg E)
Florence Court FLO 54.25 N 352.27
Market Harborough LEI 52.42 N 359.08
Herstmonceux Castle HTX 50.86 N 000.33
