V-band lightcurves of the LBV DDO68-V1 before, during and after the ’giant eruption’ and the follow-up S Dor type variations with amplitudes of 3.0 to ≳3.5 mag. Green symbols are for the background level of V_back = 20.23 mag, while red symbols are for V_back = 20.24 mag. Top panel. The V-band lightcurve of the LBV on the archive data and during the giant eruption (1988–2016). The direct HST measurements are marked by black lozenges. Middle panel. The V-band lightcurve for the LBV for giant eruption and afterwards (2004–2024). Bottom panel. The same lightcurve for LBV, for the period of 2014–2024, for a more detailed view of the S Dor phase.
