We report the spectroscopic classification of the following transients from the SALVATION project (ATel #13952). They were flagged from the ZTF public alert stream by the ANTARES alert-broker. The spectra were obtained on 2021 December 03 UT for ZTF21acmrdga and 2021 December 04 UT for ZTF21acjniho, ZTF21acourni, and ZTF21acpfduf with the Kast double spectrograph on the Shane 3-m telescope at Lick Observatory.

ZTF21acmrdga | AT2021adud | 10h43m58s | +31d07m30s | 0.034 | SN IIb | -18 to -14 days
ZTF21acjniho | AT2021acpe | 06h12m57s | +09h18m14s | 0.043 | SN Ia-91T | 10 to 22 days
ZTF21acourni | AT2021aekc | 06h27m37s | +43h36m05s | 0.087 | SN Ia-91T | 6 to 10 days
ZTF21acpfduf | AT2021aevw | 08h02m22s | +19h29m48s | 0.117 | SN Ia-91T | 6 to 10 days
Note:
Classification for the supernovae was performed with DASH (Muthukrishna et al. 2019, arXiv:1903.02557).
