We reported the characteristics of coronal mass ejection and the Ap* Index of maximum 24-hour disturbance for storm events. The geoeffective fully backside and fully frontside CMEs are identified and is correlated with the CME speed. It is observed that the occurrence rate of both GE CMEs increases with the CME speed with in limit 400 km/sec. to 1400km/sec. and then the occurrence rate decreases with increase in CME speed. The Ap* values are correlated with Fully front side Halo CMEs, the sunspot number Rz, long wave length type II radio loud burst events RL and also with the amplitude of the I-Harmonic cosmic ray intensity CRI. A positive and significance correlation is observed
