摘要: Quasi-periodic fast-propagating (QFP) magnetosonic waves and extreme-ultraviolet (EUV) were proposed to be driven by solar flares coronal mass ejections (CMEs), respectively. In this Letter, we present a detailed analysis of an interesting event in which find that both QFP EUV are excited simultaneously one eruption event. The co-existence the two wave phenomena offers excellent opportunity explore their driving mechanisms. propagate funnel-like loop system with speed 682–837 km s lifetime 2 minutes. On contrary, waves, faster component slower component, wide angular extent, experiencing reflection refraction across magnetic quasi-separatrix layer. travels 412–1287 s, whereas 246–390 s. is ~15 It revealed cospatial first wavefront train. have period about 45 ± 5 absent associated flares. All these results imply can also ejections, including CMEs or jets.
