PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org ), reports the following supernova classifications. Targets are supplied by MASTER (see http://observ.pereplet.ru/ ; Lipunov et al. 2004, AN, 325, 580), the ESA Gaia Photometric Science Alerts Team and DPAC (http://gsaweb.ast.cam.ac.uk/alerts), and taken from the IAU TNS list (see https://wis-tns.weizmann.ac.il/) . All observations were performed on the ESO New Technology Telescope at La Silla on 2016 12 21, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383). Classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) SNID provides good matches to the type IIP SN 1999gi approximately one week before maximum,
so this is likely a few days after explosion.
(2) Balmer series visible at zero redshift.
(3) SNID provides good matches to normal SNe Ia shortly after maximum.
(4) SNID provides good matches to normal SNe Ia approximately one week post-maximum.
