| Popis: | In this paper, we perform a follow-up investigation of the solar eruption originating from active region (AR) 13575 on 2024 February 9. The primary eruption of a hot channel (HC) generates an X3.4 class flare, a full-halo coronal mass ejection (CME), and an extreme-ultraviolet (EUV) wave. Interaction between the wave and a quiescent prominence (QP) leads to a large-amplitude, transverse oscillation of QP. After the transverse oscillation, QP loses equilibrium and rises up. The ascending motion of the prominence is coherently detected and tracked up to 1.68 R by the Solar UltraViolet Imager (SUVI) onboard the GOES-16 spacecraft and up to 2.2 R by the Solar Corona Imager (SCI UV) of the Lyman-alpha Solar Telescope (LST) onboard the ASO-S spacecraft. The velocity increases linearly from 12.3 to 68.5 km s at 18:30 UT. The sympathetic eruption of QP drives the second CME with a typical three-part structure. The bright core comes from the eruptive prominence, which could be further observed up to 3.3 R by the Large Angle Spectroscopic Coronagraph (LASCO) onboard the SOHO mission. The leading edge of the second CME accelerates continuously from 120 to 277 kms. The EUV wave plays an important role in linking the primary eruption with the sympathetic eruption.
