Lequizamon Pineda (Università degli Studi di Padova), A. Moore (University College Cork), E. Nilson (Lund University), A. Pisapia (INAF-OAS), J. Willingham (Macquarie University) None SN II 0.03 1 The spectrum displays broad P Cygni profiles of hydrogen, along with normal metal-line blanketing at bluer wavelengths, indicating this is a Type II supernova a few weeks after explosion. GELATO finds a good match with the spectrum 1995ad at a phase of 12 days post explosion -- which phase is a week younger than what is suggested by the ATLAS light curve. The redshift is estimated to be z = 0.03 based on the template matching. 2025TNSCR2762....1C
