TNS Classification Report No. 16714 [ 2024TNSCR.774....1G ]
Date Received (UTC): 2024-03-21 21:41:14 Sender: Sebastian Gomez

Sebastian Gomez (STScI), Daichi Hiramatsu (Harvard CfA), Edo Berger (Harvard CfA), Harsh Kumar (Harvard CfA), Peter Blanchard (Northwestern) report/s a classification of object: SN 2024bhu
Type: SLSN-IRedshift: 0.28
Remarks: 2024bhu was selected as a possible SLSN-I by our FLEET program with a P(SLSN-I) = 69% (Gomez et al., 2020, ApJ, 904, 74). The redshift of z = 0.28 was determined narrow O and H emission lines. We find a best match to the SLSN PTF09cnd using the NGSF (AstroNote 2022-191). At this redshift the peak magnitude of the SN is M_r ~ -21.6, squarely in the SLSN regime.
The following Classification spectrum was provided:
