Analysis of a Moreton Wave Associated with the X17.2/4B Flare/CME of 28-10-2003

The fast Moreton wave of 28-Oct-2003 associated with the extreme X17.2 solar flare/CME event is studied. It can be followed in four sectors, spanning almost over 360° on the visible solar disc. The mean wave velocity lies in the range of v˜ 900-1000 km s^{;-1};. We find two wave ignition centres on opposite edges of the source region, which may indicate that the wave is driven by the CME expanding flanks.
