15612 2023-09-22 00:13:14 Sebastian Gomez Sebastian Gomez (STScI), Daichi Hiramatsu (Harvard CfA), Edo Berger (Harvard CfA), Peter Blanchard (Northwestern) FLEET SLSN-I 0.161 1 FLEET 2023ous was selected as a possible SLSN-I by our FLEET program with a P(SLSN-I) = 0.40 (Gomez et al., 2020, ApJ, 904, 74). The redshift of z = 0.161 is determined from narrow host emission lines. We find a good match to SNe Ic spectra, but at this redshift the peak absolute magnitude is r ~ -20.7 mag. This, in combination with the slightly broad light curve, motivates the SLSN-I classification. 2023TNSCR2356....1G
