Abstract

So many studies are made on Geomagnetically Induced Currents (GICs) around the world. Most of these studies are made in polar and equatorial latitudes due to the high intensity of GICs observed there, which are enhanced by the auroral and equatorial electrojet currents during geomagnetic storms. In this study we are going to perform our analysis at the lower latitude specifically in Egypt at periods of maximum activity of solar cycle 24. Using magnetic field data from Misallat geomagnetic station we studied the variations in the magnetic field H component in Misallat (MLT) and compared them with other stations in lower latitudes upon data availability. In most of the studied storms the maximum (dH/dt) values coincide with the Storm Sudden Commencement (SSC), while some storms have their maximum (dH/dt) during the main phase of the storm. The maximum (dH/dt) at MLT among the whole studied period is found to be 59.4 nT/min on June 22nd,2015. Finally, GIC values are estimated along the ACSR conductors with their varying resistance values showing a maximum value of 423.6 (A.Km) along the 0.0949 (Ω/km) conductor and 21.4 (A.Km) along the 1.8769 (Ω/km) conductor.
