17616 2024-08-07 17:38:17 Sebastian Gomez Sebastian Gomez (Harvard CfA), Daichi Hiramatsu (Harvard CfA), Edo Berger (Harvard CfA), Harsh Kumar (Harvard CfA), Peter Blanchard (Harvard CfA) FLEET SLSN-I 0.402 1 FLEET 2024lch was selected as a possible SLSN-I by our FLEET program with a P(SLSN-I) = 65% (Gomez et al., 2020, ApJ, 904, 74). The redshift of z = 0.402 was determined from Mg absorption lines. We find a best match to the SLSN 2015bn about 5 days after peak. At this redshift the peak magnitude of the SN is M_r ~ -22.0, squarely in the SLSN regime. 2024TNSCR2810....1G
