 Abstract: This study aims to investigate geomagnetic jerks across the South Atlantic Anomaly during the period 2010-2020. Geomagnetic field data from magnetic observatories located in and adjacent to the South Atlantic Anomaly have been analysed to identify abrupt secular variation changes on time scales of less than 1 year. INTERMAGNET observatories such as Vassouras, Tristan da Cunha, and Port Stanley are included. Twelve-month differences of the respective observatory monthly mean of the eastward component Y was determined and external field corrections applied by means of the CHAOS-7.8 model. The observations were subsequently compared to the IGRF-13 and CHAOS-7.8 spherical harmonic models.
