Extreme-ultraviolet wave and accompanying loop oscillations

In this article, we present the observations of an Extreme-Ultraviolet (EUV) wave, which originated from the active region (AR) NOAA 12887 on 28 October 2021 and its impact on neighbouring loops. The event was observed by the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) satellite at various wavebands and by the Solar TErrestrial RElationsObservatory-Ahead (STEREO–A), EUVI and COR1 instruments with a different view angle than SDO. We show that the EUV wave consists of severalwaves as well as non-wave phenomena. The wave–nature component includes:fast–mode part of the EUV wave, creation of oscillations in nearby loops andthe appearance of wave trains. The non-wave component consists of stationary fronts. We perform the analysis of selected oscillating loops and find the periods of these oscillation ranges from 230 – 549 s. Further, we compute the density ratio inside and outside the loops and the magnetic field strength. The computed density ratio and magnetic field are found in the range of 1.08 – 2.92 and 5.75 –8.79 G, respectively. Finally using the 3D point of view of the satellites we found that the EUV wave propagates ahead of the CME leading edge.
