Herringbones in dynamic spectra and radio images. Panel a: Combined ORFEES and eCALLISTO dynamic spectrum during the herringbone bursts following the type II in Fig. 3. Panel b: Imaging of the herringbone radio sources overlaid as radio contours on AIA 211 Å running difference images showing the evolution of the CME eruption. The radio contours are shown at three NRH frequencies: 150 MHz (blue), 173 MHz (red) and 228 MHz (green). The herringbones are only observed at 150 MHz and 173 MHz. The radio contours represent 40 and 80% of the maximum intensity level in each image.
