Wijers (Amsterdam), on behalf of a larger collaborationSTARGATESN II0.056STARGATEThe spectrum is dominated by emission lines, that can be interpreted as strong He II 4686 (with a blue shoulder possibly associated with NIII / CIII) together with H-alpha and H-beta on top of a blue continuum, at a common redshift z = 0.056. A comparison with SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows that the best matching template is that of SN 1998S at 12 days before maximum. 2023TNSCR2725....1S
