The Italian Supernovae Search Project (ISSP) is the new collaboration between the main four rItalian groups operating in the extragalactic supernova research field: the CROSS of Col Drusciè Observatory - Cortina d'Ampezzo (Belluno), the MOSS of Montarrenti Observatory (Siena), the MASACAS of Monte Agliale Observatory (Lucca) and the MVSS of Montecatini Val di Cecina Observatory (Pisa).

The collaboration aims to create a joint supernova research program that allows to monitor many stellar field as frequently as possible searching for supernova explosions.

We report the following classifications of optical transients from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. Targets were supplied by the Pan-STARRS Survey for Transients (PSST) and All-Sky Automated Survey for Supernovae (ASAS-SN). All observations were made on 2015 May 16 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes: When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy. (1) We measure a Si II 6355 velocity of -11,100 km/s. (2) We measure a Si II 6355 velocity of -10,200 km/s. (3) The redshift/phase are a bit uncertain, but 0.05 < z < 0.06. (4) We measure a H-alpha velocity = -8800 km/s. (5) The spectrum shows a blue continuum.

The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of PSN J13443367+0446535 in UGC 8690. Information on this transient, discovered by F. Ciabattari, E. Mazzoni and S. Donati (Italian Supernovae Search Project) was announced through CBAT Transient Object Followup Reports (http://www.cbat.eps.harvard.edu/index.html) and is also available from the "Bright Supernova" website (http://www.rochesterastronomy.org/snimages/). The observation was performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.3 nm).

(1) The expansion velocity of the ejected material, as inferred from the position of the absorption of the Halpha, is about 7800 km/s.

Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
