The Zwicky Transient Facility (ZTF; ATel #11266) Bright Transient Survey (BTS; ATel #11688) reports classifications of the following targets. Spectra have been obtained with the Dual Imaging Spectrograph (range 340-1000nm, spectral resolution R~1000) mounted on the 3.5m telescope at Apache Point Observatory, the Spectral Energy Distribution Machine (SEDM) (range 350-950nm, spectral resolution R~100) mounted on the Palomar 60-inch (P60) telescope (Blagorodnova et. al. 2018, PASP, 130, 5003), or the Andalucia Faint Object Spectrograph and Camera (ALFOSC) on the 2.5m Nordic Optical Telescope (NOT). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) or GELATO (Harutyunyan et al., 2008, A&A, 488, 383). Redshifts are derived from the broad SN features (two decimal points), and from narrow SN features or host galaxy lines (three decimal points). Pre-explosion limits and current magnitudes are available on the Transient Name Server (https://wis-tns.weizmann.ac.il).
