5633 2019-12-03 20:21:40 Jamison Burke Jamison Burke, Koichi Itagaki, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Craig Pellegrino Global SN Project SN II 0.01952 1 Global SN Project Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe II at early phases. There are good fits to SN 1999em at a phase of +5 days. The supernova is closest to NGC 2308 (z = 0.019520, 1988PASP..100.1423M; value from NED). This redshift is well-matched by the peak of the Hα P Cygni profile. Assuming this redshift, we measure a hydrogen velocity of about 11,000 km/s from the Hα absorption. The B-band absolute magnitude roughly coeval with the spectrum is approximately -16.9 (apparent magnitude 18.1). The absolute magnitude, high velocities, and blue continuum indicate that the SN is young. Further followup is encouraged. 2019TNSCR2517....1B
