Context: .We report observations of a type II burst - the signature of a shock wave - starting at the unusual high frequency of 650 MHz during the 03 November 2003 flare. This flare is associated with the propagation of a soft X-ray coronal loop and with a coronal mass ejection (CME). Aims: .We study in this paper the origin of the shock wave in the low corona and present a kinematics analysis of the soft X-ray coronal loop and of the CME observed a few tens of minutes later. Methods: .We study in this paper the spatial and temporal relation between the soft X-ray rising loop observed by the GOES soft X-ray Imager (GOES/SXI), the type II sources observed by the Nançay Radio Heliograph (NRH) and the CME observed by LASCO (Large Angle and Spectroscopic Coronograph). Results: .This analysis shows that the type II burst observed during this flare is driven by the X-ray rising loop. Furthermore, the kinematics analysis of the X-ray coronal loop and CME shows that the two structures are related. Conclusions: .The direct comparison of the type II sources with the GOES/SXI observations clearly shows that the type II burst is ignited by the shock wave created ahead of the rising X-ray loop. Finally, we propose to interpret these different observations in the framework of an ascending magnetic structure with a reconnecting process operating in the tail of this ascending structure.
