Reguitti, L.Tomasella (INAF Padova) Padova-Asiago SN II 0.0034 1 Padova-Asiago The spectrum is consistent with that of a Type II SN, few days after explosion. The expansion velocity of the ejecta as derived from the broad Halpha emission is about 13500 km/s. The redshift z=0.0034 is derived from the narrow Halpha emission of the host galaxy, fully consistent with z=0.00331 reported by Mould et al. 2000 ApJ 529, 786 (via NED). 2021TNSCR.864....1C
