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 Catalina Real-time Transient Survey (http://crts.caltech.edu/), the La Silla Quest Survey (see Hadjiyska et al., ATel #3812), the OGLE-IV Transient Search (ATel #4495; Wyrzykowski et al. 2012), and SkyMapper (Scalzo et al. ATel #5480). All observations were performed on the ESO New Technology Telescope at La Silla on 2014 Feb 22 UT, 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 WISeREP).

(1) Nuclear location. Looks pre-max from LC. (2) Best SNID fit sn2006bp at +3d. (3) Has the features of a magnetic white dwarf. See also ATel #5912. (4) SN in NGC3905. Young Type II. Blue continuum with broad Halpha and Hbeta in emission. Narrow emission at 4657A. (5) Also named PSNJ121036761+184935 and SN2014D in UGC 7170. See ATel #5742 and CBET 3778.
