摘要	We present a case study for the global extreme-ultraviolet (EUV) wave and its chromospheric counterpart the Moreton-Ramsey Wave associated with the second X-class flare in Solar Cycle 25 and a halo coronal mass ejection (CME). The EUV wave was observed in the H alpha and EUV passbands with different characteristic temperatures. In the 171 angstrom and 193/195 angstrom images, the wave propagates circularly with an initial velocity of 600-720 km s(-1) and a deceleration of 110-320 m s(-2). The local coronal plasma is heated from log(T/K) approximate to 5.9 to log(T/K) approximate to 6.2 during the passage of the wave front. The H alpha and 304 angstrom images also reveal signatures of wave propagation with a velocity of 310-540 km s(-1). With multiwavelength and dual-perspective observations, we found that the wave front likely propagates forwardly inclined to the solar surface with a tilt angle of similar to 53 degrees.2. Our results suggest that this EUV wave is a fast-mode magnetohydrodynamic wave or shock driven by the expansion of the associated CME, whose wave front is likely a dome-shaped structure that could impact the upper chromosphere, transition region, and corona.
