10204 2021-07-27 04:42:38 Estefania Padilla Gonzalez Estefania Padilla Gonzalez, Jamison Burke, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Craig Pellegrino Global SN Project SN Ia 0.060332 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 2005hf 8 days and 2003ic 3 days after peak. The supernova is closest to WISEA J134847.54+263307.4 (z = 0.060332, 2004SDSS2.C...0000:, value from NED). Adopting this redshift we measure a Si II 6355 velocity of approximately 10,000 km/s. Adopting the distance modulus computed from this redshift (37.10 mag), the g-band absolute magnitude of the object roughly coeval with the spectrum is -18.2 (apparent magnitude 18.9, from ZTF). This absolute magnitude and velocity is consistent with an SN Ia near maximum light. 2021TNSCR2575....1G
