We have obtained an optical spectrum of SN 2021pz, which shows it to be a young Type II supernova.

The adH0cc programme for an "accurate determination of H0 with core-collapse supernovae" reports the classification of the optical transient SN 2021pz. The target was supplied by the Zwicky Transient Facility ZTF (Kulkarni 2018, 2018ATel11266....1K). The observations were performed on the night of 2021 January 12 with the ESO Very Large Telescope UT1, equipped with the FORS2 spectrograph and grism 300V, covering a wavelength range from 3400 to 9600 Å at a resolution of 10 Å.

The phase has been estimated from ZTF photometric constraints. The redshift has been determined from narrow host-galaxy emission lines.07:18:16.606+17:41:23.39SN II0.074
