Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.013433Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190), we find good fits to several young Type Ia supernovae at the redshift of the host galaxy (z=0.013433; 1998A&AS..130..333T, via NED). The MW extinction-corrected absolute magnitude at the discovery is about -15.0. We measure a Si II 6355 velocity of -15,000 km/s. The absolute magnitude and the broad features suggest this maybe as early as ~2 weeks before maximum.2019TNSCR.506....1H
