FLEET

2021hpc was selected as part of our FLEET effort to find superluminous supernovae with a P(SLSN-I) = 0.74 (Gomez et al., 2020, ApJ, 904, 74) and classified using template matching with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). The redshift of z = 0.24 was determined from the supernova features
