Abstract
We have studied about geospheric environment which has caused by the interplanetary magnetic field (IMF) and solar wind plasma parameter during the period of 2018 to 2019. In this solar cycle (SC) 24 geomagnetic storms index range Dst ≤ -90nT respectively data collect during the period, we have found 27 geomagnetic storms data. Coronal mass ejection (CME) associated with frequency of geomagnetic storms rate are 74% there the Halo CME and Partial Halo CME association rate 65% and 35% determined. Analysis of X-ray solar flare (SF) associated with majority of geomagnetic storms are 69.23% respectively, there linked solar flare (SF) classified X-class, M-Class, C-Class and B-Class relative association rate 20%, 40%, 30% and 10% determined. We have examined positive co-relation with co-relation coefficient 0.509 between magnitude of geomagnetic storms and The peak value of IMF, 0.495 between magnitude of geomagnetic storms and the magnitude of IMF, 0.22 between the magnitude of geomagnetic storms and the peak value of solar wind plasma speed (SWPS), 0.298 between the magnitude of geomagnetic storms and the magnitude of solar wind plasma speed (SWPS), 0.619 between the magnitude of geomagnetic storms and the peak value of flow pressure, 0.58 between the magnitude of geomagnetic storms and the magnitude of flow pressure, 0.402 between the magnitude of geomagnetic storms and the peak value of solar wind proton density (SWPD), 0.275 between the magnitude of geomagnetic storms and the magnitude of solar wind proton density (SWPD). We have examined this statistical relation and concluded that the Earth’s magnetosphere disturbance is caused by the coronal mass ejection, X-ray solar flare, interplanetary magnetic field, and solar wind plasma parameter.
