Andrew Howell, Curtis McCully, Craig Pellegrino, Megan Newsome, Giacomo Terreran Global SN Project SN Ia 0.03 1 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 SNe Ia near maximum light, including SN 1991M about a few days after maximum. The supernova ’s redshift is calculated from SNID, as the (z =0.031), with Si II 6355 velocity of approximately 11,000 km/s. Adopting the luminosity distance computed from this redshift (136.7Mpc ) ; the g-band absolute magnitude of the object is -16 (apparent magnitude 19.975, from ZTF, the magnitudes seem faint but that is because it is not at maximum light). This absolute magnitude and velocity is consistent with an SN Ia before maximum light. 2023TNSCR1753....1G
