We announce the classifications of six SNIa: 2020tns, 2020soy, 2020uog, 2020uca, 2020ttg, and 2020uwo.

On behalf of the Zwicky Transient Facility (ZTF) Bright Transient Survey (BTS), we report 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 (APO). All spectra were obtained during the first half-night of 2020-10-15 UT in good weather conditions, 1.3-1.6" seeing, and with the 1.5" slit rotated to the parallactic angle. The data were reduced and calibrated using the PyDIS software. Classifications were done using the spectral fitting codes SNID or GELATO. All of the following classifications have been reported to the TNS and the spectra are publicly available. We note that 2020soy, 2020ttg, and 2020uwo were first reported to the TNS by ALeRCE; 2020uog by AMPEL; and 2020uca by the project Supernova and Gravitational Lenses Follow up (SGLF).
