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 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). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). Redshifts are derived from the broad SN features (two decimal points), and from narrow SN features or host galaxy lines (three decimal points). Limits prior to detection and current magnitudes are available on the Transient Name Server (https://wis-tns.weizmann.ac.il). ZTF has reported transient classifications to TNS since those reported in ATel #12213 and would like to draw particular attention to the following SNe:
