10368 2021-08-07 18:27:01 Sebastian Gomez Sebastian Gomez, Griffin Hosseinzadeh, Edo Berger (Harvard CfA) Peter Blanchard (Northwestern) FLEET SLSN-I 0.46 1 FLEET AT2021txk was selected as part of our FLEET effort to find superluminous supernovae with a P(SLSN-I) = 0.48 (Gomez et al., 2020, ApJ, 904, 74). The spectrum matches well that of the SLSN LSQ12dlf at around 10 days after maximum. The redshift was estimated from the SN features. 2021TNSCR2719....1G
