Referred to by ATel #: 5445

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), OGLE-IV Transient Search (see Wyrzykowski et al., ATEL #4495) and Pan-STARRS (see Valenti et al., ATel #2668). All observations were performed on the ESO New Technology Telescope at La Silla on 2013 October 04 (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 (Yaron & Gal-Yam, 2012, PASP, 124, 668).

(1) Best match with SN 2007fs 5 days past maximum light.

(2) Best match with SN 2007le 7 days before max.

(3) Best match with SN 2007ci 6 days before max.

(4) SNID finds no reasonable matches with known SNe. The spectrum has broad features on a red continuum, most likely a Type I SN with unknown redshift.

(5) Best match with SN 2007A 2 days before max.

(6) The spectrum matches those of several type IIP SNe a few weeks after the explosion.
