Short summary
Based on a case study, we analyzed data from two pairs of conjugate stations to compare continuous Pc3 pulsations. Using Fourier and wavelet transform techniques, we identified similar pulsations at both locations; however, amplitudes were higher in the South Atlantic Magnetic Anomaly (SAMA) region. This enhancement may be linked to the unique conditions of the region, where energetic particles interact with both the magnetosphere and the ionosphere.
