Empirical profiling of geomagnetic induced current (GIC) due to solar activities based on spherical harmonic analysis / Nornabilah Mohd Anuar

A highly charged particle oozed out from the Sun instantly with the intense geomagnetic storm drives geomagnetic induced current (GIC) activity. The main objective of the current work is to determine the main parameter of space weather that contribute to the GIC activity at low latitude region as well as to estimate the value of the GIC in order to develop and establish an empirical characterization of GIC activity. The geomagnetic field is used as the primary data extracted from the Magnetic Data Acquisition System (MAGDAS) for the six-station located at the low latitude and equatorial region. The result reveals that the solar wind dynamic pressure is well correlates to the GIC amplitude and represent the most significant space parameter towards GIC activity at low latitude region.
