Multi-band light curves of QSO J0455-4216. Variability of around 7% is observed across all wavelengths for the entire campaign (6 months), while a smaller variability of about 5% is present within individual months of observations. Micro-variability on the order of 2%–3% is evident on timescales of days, with delayed features between bands of a few days. For comparison, the light curve of a representative reference star in the field used in constructing the AGN light curves is shown at the bottom. Dotted lines indicate a 1% variability and all light curves are vertically shifted for clarity.
