The computed density ratio and magnetic field are found in the range of 1.08 – 2.92 and 5.75 –8.79 G, respectively. Further, we compute the density ratio inside and outside the loops and the magnetic field strength. We perform the analysis of selected oscillating loops and find the periods of these oscillation ranges from 230 – 549 s. The non-wave component consists of stationary fronts. The wave–nature component includes:fast–mode part of the EUV wave, creation of oscillations in nearby loops andthe appearance of wave trains. We show that the EUV wave consists of severalwaves as well as non-wave phenomena. 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. 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. Finally, by combining SDO and STEREO-A observations, we find that the observed EUV-wave component propagates ahead of the CME leading edge.

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 neighboring loops. Our observations support the hybrid model that includesīoth fast wave and slow non-wave components. Magnetosonic wave or shock driven by the associated CME, which propagatedįaster than the ambient fast-mode speed and gradually slowed down to an Which represents the initiation of the associated coronal mass ejection (CME).īased on these results, we conclude that the EUV wave should be a nonlinear Group of expanding loops a few minutes after the start of the loops' expansion, For the origin of the EUV wave, we find that it formed ahead of a Propose that the different behaviors observed during the interactions mayĬaused by different speed gradients at the boundaries of the two active The formation of the new wavefront and the transmissionĬould be explained with diffraction and refraction effects, respectively. The wave approached AR11459, it transmitted through the active region directlyĪnd without reflection. Reflected wave was also observed simultaneously on the wave incoming side. The active region, but a few minutes latter a new wavefront appeared behind theĪctive region, and it was not concentric with the incoming wave. When the wave approached AR11465, it became weaker and finally disappeared in Intriguing phenomena are observed when the wave interacts with two remoteĪctive regions, and they together exhibit the wave property of this EUV wave. Global extreme-ultraviolet (EUV) wave propagating in the solar corona. We present observations of the diffraction, refraction, and reflection of a
