Andrew Howell (LCO/UCSB), Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Craig Pellegrino, Giacomo Terreran Global SN Project SN Ia 0.036 1 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 about a week before maximum light, including SN 2006ax 6 days before peak. A probable host (WISEA J180638.80+574922.4) can be seen in PS1 reference field, although the object has no redshift listed on NED. We adopt the best-fit SNID redshift (z=0.036) and measure a Si II velocity of approximately 11,000 km/s. Adopting the distance modulus computed from this redshift (36.0), the g-band absolute magnitude of the object roughly coeval with the spectrum is -17.5 (apparent magnitude 18.7, from ZTF). This absolute magnitude and velocity is consistent with a rising SN Ia. 2022TNSCR1500....1B
