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 1999gi and SN 1996em (SN IIb) both prior to maximum light. The supernova is closest to IC 4221 (z = 0.009637, 2005AJ....130.1037C; value from NED). Assuming this redshift, we measure a hydrogen velocity of about 12,000 km/s from the Hα absorption. The g-band absolute magnitude roughly coeval with the spectrum is approximately -16.3 (apparent magnitude 16.86). The absolute magnitude, high velocities, and blue continuum indicate that the SN is young. Further followup is encouraged.
