Overview of the eruption on 2024 October 3. Panel (a): an SDO/HMI LOS magnetogram. The red square outlines the fields of view (FOVs) in panels (b)–(d) and Figure 2(a1). The green curve inset displays the GOES soft X-ray flux variation of the X9.0 flare. Panel (b): the SDO/AIA EUV data in 131 Å wavelength. The SDO/HMI LOS magnetogram at +500 G and −500 G are shown by red and blue solid contours, respectively. Panels (c) and (d): the SDO/AIA 94 Å and 211 Å observations. The cyan and yellow dashed lines in panel (d) outline two sets of postflare loops. Panel (e): a SOHO/LASCO C2 image.
