X-ray flux seen in the two GOES channels (1–8 Å and 0.5–4 Å) on 2 April 2022. The first flare corresponds to the filament eruption, which is the focus of this paper, while the second confined flare occurred later on in the same region. The vertical dashed black line shows the beginning of the impulsive phase of the first flare, while the two vertical dashed grey lines show the peaks of the two flares. Both flares were classified as M-class flares. The bottom of the graph shows the temporal coverage of the observations by the different optical instruments discussed in the paper, namely SPICE (green), EIS (blue), EUI/HRI (yellow) and IRIS (orange).
