| contents | We present an investigation of the Extreme-Ultraviolet (EUV) wave linked to the flare that occurred on 28 October 2021, along with the associated coronal loop oscillation and type II radio burst. The EUV wave was observed by multi-viewpoint with Solar Dynamics Observatory and Solar Terrestrial Relations Observatory - A. The associated coronal mass ejection (CME) was observed by Large Angle and Spectrometric Coronagraph (LASCO) as well by COR1 coronagraph. From the multi-view observation, we found that the EUV wave is propagated ahead of the connected CME. The coronal magnetic field measurement was performed by the coronal loop oscillations as well by the associated m-type II radio burst observations. We found the magnetic field strength values computed by both methods are consistence and are in the range of ~ 5 to 10 G. |
