Onset and eruption of the flux ropes. Panels (a1)–(a5): the SDO/AIA EUV data. Panel (a6): a time-distance plot along “S1” in panel (a4) displaying the eruption of FR1 and FR2. The white box in panel (a1) marks a brightening. The cyan dotted lines in panels (a2)–(a5) and the green ones in panels (a2) and (a4)–(a5) denote FR1 and FR2, separately. The red and blue closed curves in panels (a4) and (a5) (denoting the emerging dipole in Figure 2(c1)) are the contours of the SDO/HMI LOS magnetogram (11:34:15 UT) at +150 G and −400 G, respectively. To display the eruption process, an animation of the AIA 131 Å, 304 Å, 211 Å, and 193 Å observations from 2024 October 3 12:05 UT to 12:15 UT is available, with a duration of 5 s.
