Craig Pellegrino (UVA), Joseph Farah (UCSB/LCO), D. Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Giacomo Terreran report/s a classification of object: SN 2023rai

Type: SN II
Redshift: 0.023

Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe II, including SN 2006bp approximately 35 days after explosion. The supernova is closest to ESO 552- G 038 (z = 0.022629, 20096dF...C...0000J; value from NED). This redshift is well-matched by the peak of the strong Halpha feature in the spectrum. The ATLAS light curve shows a plateau lasting at least 30 days, consistent with the phase estimate from the SNID fit.

The following Classification spectrum was provided:
