The spectrum features a blue continuum with prominent P-Cygni lines of H and He. Cross-correlation of the spectrum with a template library using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows a good match to the type-IIP SN 2014et at -3 days, confirming the results of Hosseinzadeh et al. (ATel 8748). The host redshift of z = 0.004 from numerous narrow interstellar emission lines yields an expansion velocity for the supernova of 10,700 km/s, measured to the trough of the H-alpha line. We thank K. Stanek (OSU) and G. Pignata (U. Andres Bello) for providing finding charts.
