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.

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).

 
 
Name                  | Date (UT)       |        v        |   Type      | Phase   | Notes 
PSN J13443367+0446535 | 20150411.90     | 6938 km/s       |    II       | 1 month | (1)    
 

(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.

The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of PSN J08593491+4555343 in UGC 4709. Information on this transient, discovered by F. Ciabattari, E. Mazzoni and G. Petroni (Italian Supernovae Search Project) is available from the "Bright Supernova" website (http://www.rochesterastronomy.org/snimages/) and from CBAT Transient Object Followup Reports (http://www.cbat.eps.harvard.edu/index.html). The observations were performed with the Asiago 1.22 m Galileo Telescope (+B&C spectrograph; range 330-790 nm; resolution 0.9 nm).
