THE SOLAR CYCLE VARIATION OF CORONAL MASS EJECTIONS

In this paper, Coronal Mass Ejection (CME) events observed with SMM (C /P) during l98O and l984 are reated with flares and eruphve filaments which occund in the saine periods. By Studying the distributions of velocity, there properties of CME is given,The results reveal that there are some changes in the frequency of occurrence of CMEx related with flares and filaments in the different period of solar cycle. From its maximum to the minimum years, the flares relatal frequency of occurrence of CMEs declined, and the filaments reated frequency of occurrence increased.Otherwise, energy of the activities associatad with CMEs is probably varied with ejective velocity . In generel, the faster the velocity is, the higher the energy of the activities is.
