Jamison Burke, David Sand, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino report/s a classification of object: SN 2020uxz
Type: SN IaRedshift: 0.008246
Remarks: 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 SN 2003du 11 days before peak. The supernova is closest to NGC 0514 (z = 0.008246, DM = 32.1; 1998AJ....115...62H and 2014MNRAS.444..527S; NED values). Adopting this redshift we measure a velocity of approximately 16,000 km/s for the Si II 6355 feature, and 17,000 km/s for the Ca II NIR triplet. Adopting this distance modulus, the object’s absolute magnitude at discovery on 2020-10-05 13:45:30 is -15.6 (apparent magnitude 16.5). The high velocities and faint absolute magnitude indicate that the supernova is young. Further followup is encouraged.
