Remote sensing observations of the EUV wave, the CME, and the white-light shock wave from two different viewpoints. Panels a–d: EUV running-difference images recorded nearly simultaneously from SUVI (a and b) and STEREO-A EUVI (c and d) at 195 Å during the early stages of the EUV wave expansion in the low corona. The EUV wave front is labeled and outlined with the red lines. Panels e–h: running-difference images in white-light from SOHO/LASCO-C2 (e and f) and STEREO-A/COR2 (g and h). The CME is labeled and the white-light shock wave is labeled and outlined with red lines.
