X-ray spectra and light curves. Panel (a) shows the variation in the three selected X-ray spectra taken during the brightest phase, the minimum flux, and during the second peak. The round markers represent unfolded data and the solid lines represent best-fit model. Black represents the brightest X-ray observation from Swift, magenta represents the minimum flux observation from eROSITA and blue represents the second peak from Swift. Panels (b) and (c) shows the mean-normalized light curves exhibiting short-term variability in the decaying part of the flare, between MJD 58880 to 58920 for 0.2–5.0 keV X-ray and the UVW2 and UVM2 band, respectively.
