ABSTRACT In the present paper dependence of geomagnetic activity on the solar-wind plasma and interplanetary magnetic field (IMF) parameters has been studied. We have taken interplanetary solar wind data at the instant of Dst minimum. Our study consists of 200 geomagnetic storms weighed by disturbance storm time (Dst) < -50 nT, observed during solar cycle 23. The study suggests that the strength of the geomagnetic storm is strongly dependent on th...
