Global SN Project

Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe II, specifically SN 2005cs (SN IIP), one day before maximum. The supernova is closest to SDSS J083031.36+181207.5 (z = 0.010424, 2016SDSSD.C...0000; value from NED). This redshift is well-matched by narrow host hydrogen emission lines. Assuming this redshift, we measure a Hα absorption velocity of about 20,000 km/s and a similar He velocity from He 5876. The B-band absolute magnitude roughly coeval with the spectrum is approximately -17.5 (apparent magnitude 17.99). The absolute magnitude, high velocities, and blue continuum indicate that the SN is young or near peak.
