Upper panel : Radio images at distinct frequencies which show the complexity of the emitting region ; the emission expands toward the northern hemisphere.

Lower panel : Composite image of a SOHO/LASCO C2 image with a NRH image at 164 MHz showing that there is a close correspondence between the extent in latitude of the white light CME and the sites of the radio emission
