PESSTO, the Public ESO Spectroscopic Survey for Transient Objects
(see Valenti et al., ATel #4037; http://www.pessto.org ), reports the
following supernova classifications.
Targets were supplied by the La Silla-Quest survey (see Hadjiyska
et al., ATel #3812) and the Catalina Real-time Transient Survey
(http://crts.caltech.edu/). All observations were performed on the
ESO New Technology Telescope at La Silla on 2012 April 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 can be obtained from http://www.pessto.org (via WISEASS).
