Geomagnetic disturbances have been identified with respect to their sources for 1977-1983. The disturbance level was found using the daily planetary index Ap. High-amplitude (~ 50), mean-amplitude (~ 24) and low-amplitude ( ~ 12) disturbances are caused by solar flares of importance >\_ 1, coronal h
