- Abstract
We are estimated the arrival time of ICME shock to the Earth's magnetosphere during the solar cycle 23rd , for the period 1996-2005, by using certain temporal and spatial conditions. We selected the Data of the SSC events from Preliminary Reports of the ISGI (Institut de Physique du Globe, France). While the associated CMES during the same period are selected from SOHO/LASCO/C2. We construct a numerical model to estimate the arrival time of the CME reached the Earth's magnetosphere. According to our model, we found high correlation between CMEs and their shocks (R = 75%). In addition , we studied the characteristics of the CMEs which reached to Earth's magnetosphere. Also we examined the relation between the logarithms of the halo CME energy and the duration of the associated intense geomagnetic storms(Dst < ‑100nT ). We found a significant correlation (R = 0.82) between the length of the duration of the intense geomagnetic storms and the related halo CME energies. This means that the halo CMEs events is the main source of the energy transfer processes into the Earth's magnetosphere.
