The type II burst in dynamic spectrum and radio images. The top panel shows a zoomed-in dynamic spectrum of the onset of the type II harmonic lanes. The arrows located to the left of this panel represent the frequency sub-bands that were imaged in the bottom panels. The bottom panels show the 70% radio contours at the time and frequencies denoted in the top panel using the same colouring, overlaid on AIA 211 Å running difference images of the eruption. The radio contours and AIA images have the same time stamps, as shown in the panels. The time labels in this figure are UT observer times.
