Full Stokes dynamic spectra of the type II burst observed by LOFAR. In both (a) and (b), the Stokes I (top left), U (bottom left), Q (top right), and V (bottom right) are displayed. (a) Dynamic spectrum in the range of approximately 20−80 MHz at 11:22–11:42 UT. The dashed rectangle in each panel outlines the part of the spectra shown in (b). (b) Zoomed-in parts of the dynamic spectra in the range at 11:35:00–11:36:45 UT. The rectangles in each panel outline the part of the spectrum with the highest amount of the Stokes V signal and the least leaked signal in Stokes Q.
