Abstract: We study a sample of complex events; each includes a coronal type II burst,accompanied by a GOES SXR flare and LASCO CME. The radio bursts were recordedby the ARTEMIS-IV radio spectrograph 100-650 MHz range; the GOES SXR flaresand SOHO-LASCO CMEs, were obtained from the Solar Geophysical Data SGD andthe LASCO lists respectively. The radio burst-flare-CME characteristics werecompared and two groups of events with similar behavior were isolated. In thefirst the type II shock exciter appears to be a flare blast wave propagating inthe wake of a CME. In the second the type II burst appears CME initiated thoughit is not always clear if it is driven by the bow or the flanks of the CME orif it is a reconnection shock.
