Obsdate: 2019-07-02 08:43:34
Instrument: LRIS
Telescope: Keck I 10m

Remarks: Spectrum shows several broad features which we have not yet successfully matched to any previous transient. However, narrow host-galaxy emission lines are evident at z=0.3642 to fix the redshift and broad hydrogen is clearly absent, so we classify this as a SLSN-I.
