Benetti (INAF - Osservatorio Astronomico di Padova) Padova-Asiago SN II 0.0055 1 Add Padova-Asiago The low S/N spectrum (because of scattered clouds and bright Moon) shows a blue continuum and hints of broad H Balmer features consistent with a young type II SN. We also detect narrow Halpha and [OIII] emission lines from a nearby HII region from which we derive a redshift of 0.0055 in agreement with z=0.0058 reported for NGC 2805 by Almeida et al. 2011, ApJ 735 via NED. 2019TNSCR1046....1C
