Light curves of SN 2018big and its sibling SN 2019nvm in magnitude space using bins of 25 d. The g (green) and r (orange) bins follow the tail of SN 2018big until it disappears in the noise. About 450 d after the peak of SN 2018big, new detections are identified in the binned photometry. The individual observations remain upper limits, although their shape hint to the true nature of these late-time detections.
