GOES (top: 1–8Åand 0.5–4Å) and RHESSI (bottom: 6–12, 12–25, 25–50, 50–100 and 100–300 keV) lightcurves for the chosen flare SOL2013-05-13T02:12. The two minute time of study from 02:08 to 02:10 UT is shown by the pink band between the two vertical dashed lines. The “jumps” in the RHESSI lightcurve occur due to instrumental attenuation changes reducing the X-ray flux reaching the detectors. At this time, RHESSI was in attenuator state A3, meaning that both the thin and thick attenuators cover the detectors.
