Abstract
We investigate the role of the coronal mass ejections (CMEs) (by using soft X ray solar emission as proxy data) in producing the nonrecurren t geomagnetic storms in the period 1969-1974. The linkage between thes e phenomena is confirmed: however, it turns out that CMEs associated w ith chromospheric flares, accompanied by type 4 radio emission, are th e most effective in perturbing the geomagnetic field.
