We report a historic Ks-band light curve spanning over three decades of the FUor PGIR20dci recently discovered by Hillenbrand et al. (2021) . We find some minor variability of the object prior to the FUor outburst, an initial rather slow rise in brightness, followed in 2019 by a much steeper rise to the maximum.
