Intensity perturbation profiles illustrating the evolution and propagation of the EUV waves in different directions (see sectors plotted in Fig. 8): (a) first wave in NW sector, (b) first wave in SE sector, (c) second wave in SE sector. Big circles (red – first and black – second wave) mark the peak amplitude of each profile, small circles (orange – first and gray – second wave) mark the determined wavefront positions (extracted at 30% of the peak value) used for the EUV wave kinematics plotted in Fig. 10. A movie accompanying the figure is available online (movie5), showing the dynamics of the intensity perturbation profiles with a cadence of 24 s.
