Megan Newsome (LCO/UCSB), Joseph Farah, D. Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino, Giacomo Terreran report/s a classification of object: SN 2024gy

Type: SN Ia
Redshift: 0.001183

Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to young SNe Ia, including a match to SN 2002bo 13 days before peak. The supernova is closest to SDSS J121551.28+130701.2 (z = 0.001183, 2016SDSSD.C...0000:, value from NED). Adopting this redshift we measure a Si II 6355 velocity of approximately 17,000 km/s. This velocity is consistent with an SN Ia approaching maximum light. Follow-up is encouraged.
