Fig. 2
Dynamic spectrum (from the beam reported with the filled blue circle in Fig. 1) of a type II radio burst recorded on 2013 October 26 at 9:30 UT, showing fundamental (F) and harmonic (H) components, both split into two lanes. The spectrum was obtained with the LOFAR Superterp LBA antennas. The decrease in sensitivity below 29 MHz is due to the filter for the HF band.
