Description 142-148
Today’s challenge for space weather research is to quantitatively predict the dynamics of the magnetosphere from
measured solar wind and interplanetary magnetic field (IMF) conditions. Correlative studies between geomagnetic storms
(GMSs) and the various interplanetary (IP) field/plasma parameters have been performed to search for the causes of
geomagnetic activity, which are important for space weather predictions. In this paper we have found relation between solar
activity and geomagnetism during the solar cycle-24. Geomagnetic storms (GMSs) were less during the observed cycle, no
severe and great storms had occurred during that cycle.Yearly occurrence of GMSs does not exactly match with phase of
solar cycle-24. Similarly occurrences of Coronal mass ejection (CMEs) also do not exactly follow the phase of solar cycle
but yearly occurrence of GMSs follow the yearly occurrence of Halo CMEs. Consequently, halo CMEs are responsible for
the occurrence of GMSs during the solar cycle-24. The behavior of the total average interplanetary magnetic field (IMF)
Btotal, Southward component of IMF (Bz), Solar wind temperature, Solar wind density, Solar wind dynamic pressure, Solar
wind velocity (V), and Ey along with geomagnetic storms (Dst index) have been analyzed in this paper. Relation of Dst with
Btotal, Bz, Speed V and Ey has been found good during the cycle-24.
