8235 2020-12-17 16:27:11 Andrea Reguitti Andrea Reguitti Padova-Asiago SN IIP 0.041 1 Padova-Asiago The low signal-to-noise spectrum shows a prominent Halpha in emission as in Type II SNe, consistently with that seen in the P60/SEDM classification spectrum (Dahiwale et al. 2020, TNSCR, 3122). Gelato (Harutyunyan et al. 2008, A&A, 488, 383) returns fair matches with spectra of the peculiar type IIn SN 2005gj (Prieto et al 2007, arXiv:0706.4088) about two months after maximum. The redshift is determined from the Halpha line in the spectrum of the supernova, and is consistent with the one (z=0.045) reported by Dahiwale et al. 2020. No redshift is available for the host galaxy. 2020TNSCR3825....1R
