Scientific paper

Radio type II emission is thought to be produced by energetic electrons that are accelerated at shocks in the solar corona and in interplanetary space. Simultaneous imaging observations of both, the radio emission and the shock, are rare, especially in the lower corona. Here, we present imaging observations in radio waves and soft X-rays of a type II burst that occurred on November 3, 2003 during a GOES X3 flare. The radio type II burst starts at an unusally high frequency (600 MHz) and can therefore be imaged with the Nancay radio heliograph. Simultaneous soft X-ray observations provided by GOES SXI show a faint, fast moving (~800 km/s) loop-like emission in the lower corona (0.1-0.3 solar radius above the photosphere) that spatially and temporally correlates with the Coronal Mass Ejection (CME) later seen in white-light with SOHO/LASCO. Therefore, the observed SXR front is most likely emitted when the CME shock is in the lower corona. The radio type II emission is observed to occur infront of the SXR emission and is only seen from a single location, but not all along the shock front.
