Study of coronal mass ejections with solar activity and geomagnetic index

In the present study we have investigated the some statistical properties such as occurrence rate, speed of halo partial halo CMEs and all type of CMEs observed during the periods 1996 to 2014 by using solar heliospheric observatory (SOHO) and large angle spectrometric coronagraph (LASCO) data. We investigate the relationship between coronal mass ejection (CMEs), Sunspot number (Rz) and geomagnetic index Ap variations of long term basis. The 650 halo, 1692 partial halo, and 24641 all CMEs which include halo and partial halo event have been observed for the solar cycle 23 to ascending phase of recent solar cycle 24, (years 1996 to 2014). It has been found that the positively correlated between linear speed (Km\sec) all CMEs, halo event CMEs, PHalo event CMES, with sunspot number and geomagnetic index. We found that the rate of occurrence of CMEs is good correlated with sunspot number (Rz) and geomagnetic index (Ap).
