The northeast limb of the Sun captured by AIA 304 Å at 17:54 UT is shown in panel (a). The blue box represents the region where the prominence eruption occurred. This region (inside the blue box) is displayed in panel (b). The green box in panel (b) represents the FOV of IRIS/SJI. The top part of the jet, indicated by the white arrow, was not observed by IRIS. Panel (c) displays the X-ray flux observed by GOES, starting at 17:30 UT and ending at 19:00 UT. The red curve corresponds to the SXR flux, and the blue curve corresponds to the HXR flux. The first peak (black dashed vertical line) and the second peak (black solid vertical line) correspond to the C4.0- and C4.2-class solar flares. The first flare started at 17:43 UT (marked by the black arrow) and the second flare started at 18:15 UT.
