Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla GonzalezGlobal SN ProjectSN II0.010971Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to young SNe II. Broad hydrogen features are seen on top of a blue continuum. The supernova is closest to IC 4501 (z = 0.010971, 2005A&A...430..373T; value from NED). This redshift is well-matched by narrow host emission lines in the spectrum. The B-band absolute magnitude roughly coeval with the spectrum is approximately -15.8 (apparent magnitude 17.6). 2021TNSCR2248....1P
