“…As for satellite and spacecraft orbiting through the SAA, it will be beneficial to have an update of the magnetic field strength as it can provide the regional magnetic intensity in that area. Therefore, research carried out regarding the SAA can be used as a reference in the satellite launch and can increase knowledge of the geomagnetic field (Nasuddin et al, 2015).…”

Abstract. This research intends to characterize the South Atlantic Anomaly (SAA) by applying the power spectrum analysis approach. The motivation to study the SAA region is due to its nature. A comparison was made between the stations in the SAA region and outside the SAA region during the geomagnetic storm occurrence (active period) and the normal period where no geomagnetic storm occurred. The horizontal component of the data of the Earth's magnetic field for the occurrence of the active period was taken on 11 March 2011 while for the normal period it was taken on 3 February 2011. The data sample rate used is 1 min. The outcome of the research revealed that the SAA region had a tendency to be persistent during both periods. It can be said that the region experiences these characteristics because of the Earth's magnetic field strength. Through the research, it is found that as the Earth's magnetic field increases, it is likely to show an antipersistent value. This is found in the high-latitude region. The lower the Earth's magnetic field, the more it shows the persistent value as in the middle latitude region. In the region where the Earth's magnetic field is very low like the SAA region it shows a tendency to be persistent.

“…As an extension to do work done by Nasuddin et al (2019), four regions which are the SAA region, low latitude region, middle latitude region and high latitude region are being studied during different year to examine the influence of solar cycle 24 on the regions. Therefore, a research carried out regarding SAA can be used as a reference in the satellite launch and increase knowledge in the field of geomagnetic field (Nasuddin et al, 2015).…”

Abstract. For this research, four regions have been studied which are the South Atlantic Anomaly (SAA) region, low latitude region, middle latitude region and high latitude region. The active period which is the period when the geomagnetic storm occur chosen to be analyzed is on 6 August 2011 and 12 April 2014 and the normal period, a period when no geomagnetic storm happen is on 24 July 2011 and 14 May 2014. Year 2011 is chosen to be analyze in order to study the SAA region during the ascending phase of the solar cycle 24 and in year 2014, where the occurrence of the maximum phase of solar cycle 24 occur. The research is carried since there is no clear characterization of the SAA during ascending as well as maximum phase based on power spectrum analysis method. The Earth's magnetic field component chosen to be analyzed is the horizontal intensity (H) due to its sensitiveness regarding geomagnetic activeness. From the research conducted, the result reveal SAA region has a tendency to be persistent during both period compare to other region during both phases. Other regions in the research experience a tendency to be persistent and antipersistent.
