Andrew Howell, Curtis McCully, Stefano Valenti Global SN Project SN Ia 0.017 1 1 Global SN Project Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find several good fits to the normal Type Ia supernovae in the week before maximum light at redshifts consistent with that of the proposed host galaxy (z=0.017; Barmby & Huchra 1998, AJ, 115, 6 via NED). The supernova is highly extinguished by its host galaxy, making a more precise phase estimate difficult. 2017TNSCR1002....1H
