Abstract

Geomagnetic storms are prevalent during high solar activity periods and are characterized by prolonged depression of the horizontal component (H) of the Earth’s magnetic field. The depression in H is characterized by the geomagnetic index Dst which lies between -100 to -200 nTfor intense and <- 200 nT for very intense storms. The long period of interconnection of the southward interplanetary magnetic field (IMF BS) with the Earth’s magnetic field transports solar wind energy into the Earth’s magnetosphere. This is the primary cause for the formation of geomagnetic storms.
