AT 2018bwo optical and NIR photometry. The light curves include selected data from the public surveys and from Blagorodnova et al. (2021) to fill our observational gaps. The very few data points in the ATLAS-c band are not shown. The solid lines on the left represent the magnitudes of the quiescent progenitor from Blagorodnova et al. (2021), converted to Johnson-Cousins B, V, and I following the prescriptions of Harris (2018). To facilitate the comparison with the i-band light curve of AT 2018bwo, the I-band magnitude of the progenitor is reported in the AB magnitude system. The dot-dashed lines represent the uncertainties in the progenitor detections, which are of ∼0.04 mag in all filters. The phases are in days from the earliest LRN detection (MJD = 59252.9).
