Abstract: The signatures of Coronal Mass Ejection (CME) associated interplanetary disturbances are called as Interplanetary Coronal Mass Ejections (ICMEs). In the present study, 69 events of ICMEs have been utilized to derive their relationship with the geomagnetic activity for the period of 1996-2002. A significant positive correlation between Ap-index and ICME speed has been observed. Results of present analysis suggest that ICMEs can produce geomagnetic activity with an increase in geomagnetic Ap-index and decrease in Dst-index.
