1500 2017-12-04 19:36:57 Griffin Hosseinzadeh Griffin Hosseinzadeh, Iair Arcavi, D. Andrew Howell, Curtis McCully, Stefano Valenti Global SN Project SN Ia 0.019 1 1 Global SN Project Using Superfit (Howell et al. 2005, ApJ, 634, 1190), we find good fits to several Type Ia supernovae 0-2 weeks before maximum light at a redshift of the proposed host galaxy (z=0.019; Falco et al. 1999, PASP, 111, 438 via NED). We measure a Si II velocity of about 16,000 km/s, implying the supernova was discovered soon after explosion, but the absolute magnitude at discovery was about -19, implying it was discovered near maximum light. Together, these could either indicate a young overluminous supernova or a high-velocity supernova at peak. 2017TNSCR1369....1H
