Background
The Ascension Island magnetic observatory is situated 40m outside the perimeter fence of the Cable and Wireless Earth Station, Donkey Plain, on the south-west side of the site.
The observatory was installed by the British Geological Survey with financial support from a consortium of oil companies and became operational in September 1992.
We also support the operation of a British Antarctic Survey VLF Radio Wave Detector as part of a worldwide network of lightning detectors.
Ascension Island magnetic observatory is part of the INTERMAGNET network.
