We examine a sample of type II burst and their associated CMEs and Flares. The radio events were recorded by the ARTEMIS-IV radio spectrograph, in the 100-650 MHz range, in the 1998-2000 period while the flares and CMEs were from the SGD and the LASCO lists respectively. These data are compared with changes of solar wind parameters and geomagnetic indices in order to establish a relationship between solar energetic events and their effects on geomagnetic activity.
