9703 2021-05-19 18:51:17 Sebastian Gomez Sebastian Gomez, Griffin Hosseinzadeh, Edo Berger (Harvard CfA) Peter Blanchard (Northwestern) FLEET SLSN-I 0.303 1 FLEET 2021gtr was selected as part of our FLEET effort to find superluminous supernovae with a P(SLSN-I) = 0.43 (Gomez et al., 2020, ApJ, 904, 74) and classified using template matching with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). The best match is to SNe Ic, but at the redshift of z = 0.303 (determined from weak host emission lines) the absolute peak magnitude is around -20.8, suggesting the object is a SLSN-I. 2021TNSCR1716....1G
