Kinematics of the CME and herringbone bursts. (a) Height–time plot showing the propagation of the northern CME flank (blue circles), deprojected EUV wave front (purple circles), herringbone sources at 173 (yellow triangles) and 228 MHz (orange triangles), and deprojected Earth–facing flank (large magenta circles). (b) Speed estimates of the northern CME flank and EUV wave front using custom acceleration functions fitted to the height–time points in panel a.
