Sequential base difference images in AIA 193 Å (upper panels) displaying the evolution of the wave, and base difference time-slice images (bottom panels) along the sectors S1 − S4 (dashed lines in panels a) − b)). S1 starts from the eruption center, indicated by the plus, and S2 − S4 emanates from W. The box in panel a) shows the FOV of Fig. 4. Wave signatures are indicated by arrows, with the linear fitted velocities and quadratic fitted acceleration attached above. The temporal evolution in the AIA 193 Å as seen in the upper panels is shown in the movie available in the online edition.
