PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see
Valenti et al., ATel #4037; http://www.pessto.org ), reports the
following supernova classifications. Most targets were supplied by the
La Silla-Quest survey (see Hadjiyska et al., ATel #3812). SNhunt119
was discovered by S. Howerton in course of the Supernova Hunt project
(http://nesssi.cacr.caltech.edu/catalina/current.html). All
observations were performed on the ESO New Technology Telescope at La
Silla on 2012 April 11 and 12, 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 can be obtained from http://www.pessto.org (via WISEASS).
