The estimated linear velocities are 600 and 200 km/s. We interpret them as fast mode MHD wave and slow EIT wave. As the fast EUV wave progresses, it creates oscillations in a coronal loop lying at ~ 225 Mm from the flare site. Using coronal seismology, we have computed the minimum energy of the fast EUV wave transferred to the oscillating loop. The study of dynamics reveals another interesting feature. We found that the fast EUV wave encounters various Quasi-Separatrix Layers (QSLs) and leaves stationary fronts at these QSLs. The event is associated with CME and type II radio burst. |
