Andrew Howell, Daichi Hiramatsu, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.038Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several Type Ia supernovae two to three weeks after maximum. The best-fit redshift from both SNID and Superfit is 0.038. Verification of this redshift is difficult as there is no obvious host galaxy, either in images of the SN or in contaminating spectral lines, but the phase and distance modulus are in agreement with the ATLAS lightcurve. We measure a Si II velocity of about 10,000 km/s and a Ca II velocity of about 12,000 km/s.
