The long-term ZTF and Swift/UVOT light curves after host subtraction and the Galactic extinction correction. The dotted line marked the time first detected X-ray QPE (L. Hernández-García et al. 2025a). The gray shadow marks the period when the X-ray QPE and UV counterpart are simultaneously observed.
