Radio images of the type II burst using two different baselines. The images are at 12:25:34 UT, time which is marked as a white dashed line in the dynamic spectrum in Fig. 1, and cover three frequency subbands: 57.6, 67.7 and 78.9 MHz, from left to right, respectively. The top panels make use of a baseline of 15 and 10 km, while the bottom panels have a larger baseline of 20 and 32 km, in the East-West and north-south directions, respectively. The size of the beam corresponding to each frequency subband and baseline is shown in the bottom left corner of each panel. In this paper, we present a comprehensive analysis on the spatial properties of a multi-lane type II radio burst and associated shock wave using new and unprecedented high-resolution radio imaging observations with LOFAR.
