eROSITA light curve of 1eRASS J054422.3−672729 in the energy bands 0.2−2.0 keV (soft; top), 2.0−5.0 keV (hard; middle) and the HR defined from those two bands (bottom). The light curve is binned such that there is a minimum of 1 net count in each band and a minimum of 10 net counts in the sum of the two bands per time bin. The flares at ∼373 and ∼730 days are marked with dotted grey lines and can be best seen in the soft band. The HR light curve indicates spectral softening at those times. Note that time gaps between eRASSs are cut out for readability.
