Absolute magnitudes of SN 2020cxd (black stars) together with the LCs of other LL SNe IIP, as well as for the normal Type II SN 1999em (green circles). We highlight SN 2013am (orange circles) which is the brightest within the LL SN II sample, and SNe 1999eu (purple circles) and 1999br (blue circles) which are the faintest. We also use a larger marker for SN 2018hwm (red hexagons), which was also monitored by ZTF in gri photometry. The other SNe are displayed with smaller and fainter markers. The LCs are plotted versus rest frame days past explosion. The radioactive cobalt decay rate is shown as a black line in the r- and i-band panels for comparison. The photometric data were obtained via the Open Supernova Catalog. Data reference for SN 1999em is Leonard et al. (2002), and for the LL SNe II these are listed in Table 1.
