McCullyGlobal SN ProjectSN Ia0.008Global SN ProjectUsing SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find a good fit to the normal Type Ia SN 2002bo 13 days before maximum light at redshift z=-0.001. This negative redshift from SNID, compared to the host galaxy redshift of z=0.008 (Cappellari et al. 2011, MNRAS, 413, 813), likely indicates that the supernova is even younger than -13 days.
