Few geomagnetic ground observations exist of the Earth’s strongest core field anomaly, the South Atlantic Anomaly (SAA). The geomagnetic repeat station on the island Tristan da Cunha, located half-way between South Africa and South America at 37° 05’ S, 12° 18’ W, is therefore of crucial importance....
