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 pre-maximum SNe Ib, including SN 1999ex 5 days before peak. The supernova is closest to NGC 6118 (z = 0.005247; 1998AJ....115...62H). Assuming this redshift, we measure velocities of approximately 14,000 km/s for the Ca II NIR triplet and approximately 9,000 km/s for the Si II 6355 line.
