Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino Global SN Project SN Ia 0.011201 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, including the underluminous SNe 1986G and 2006bt a few days before maximum. Adopting ESO 194- G 021 as the host (z = 0.011201, 1996ApJS..107..201L; value from NED), we measure a speed of 13,000 km/s for both the Si II 6355 line and the Ca NIR triplet. Further follow up is encouraged. 2020TNSCR2838....1B
