Abstract:
Classification report for ZTF discoveries: SNe Ia: 2020skp, 2020sko, 2020seo, 2020sfs, and SN II: 2020tkl.

The Zwicky Transient Facility (ZTF; ATel #11266) Bright Transient Survey (BTS; ATel #11688; see also Fremling et al. 2019, arXiv:1910.12973) reports spectral classifications obtained with the Dual Imaging Spectrograph (range 340-1000nm, spectral resolution R~1000) mounted on the 3.5m telescope at Apache Point Observatory, and reduced with PyDIS (Davenport et al. 2016, http://doi.org/10.5281/zenodo.58753). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) or GELATO (Harutyunyan et al., 2008, A&A, 488, 383). All of the following classifications have been reported to the TNS and the spectra are publicly available.

ZTF is a project led by PI S. R. Kulkarni at Caltech (see ATEL #11266), and includes IPAC; WIS, Israel; OKC, Sweden; JSI/UMd, USA; UW,USA; DESY, Germany; NRC, Taiwan; UW Milwaukee, USA and LANL USA. ZTF acknowledges the generous support of the NSF under AST MSIP Grant No 1440341. Alert distribution service provided by the DiRAC Institute at the University of Washington. Alert filtering is being undertaken by the GROWTH marshal system, supported by NSF PIRE grant 1545949.
