Binned r-band observations of the objects whose late-time detections are consistent with a galaxy nucleus (see Table 4) and are potentially transient events unrelated to the original SN. Upper limits are shown with downward arrows. The r-band light curve of the slowly evolving ambiguous nuclear transient AT 2020ohl (ASASSN-20hx, Hinkle et al. 2022) is also shown for comparison. As the late-time signal in AT 2017fwf was found to be significantly offset from the SN location, we show the processed light curve at the host nucleus location instead.
