UVW2 Swift/UVOT and XMM-Newton/OM light curves with 120 s bins. The UVOT light curves from dates outside the low-flux optical state (years 2016 and 2021; top and bottom panels) show strong variability, whereas the light curve from the 2019 XMM-Newton/OM observation (middle panel) shows a much fainter source with no significant variability.
