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 spectroscopic classification of SN2016aa in PGC 22658 through observations obtained with the 1.82-m Copernico Telescope in Asiago (+ AFOSC; range 340-820 nm, resolution 1.3 nm).

A low signal-to-noise spectrogram obtained on Jan 04.97 UT indicates that SN2016aa is a Type II SNe, a few weeks after the explosion. The redshift, as inferred from the narrow emission lines of the host galaxy, is z = 0.03.

Photometry was obtained with AFOSC on Jan. 04.98 UT, providing the following magnitudes (sloan, ABmag): g = 18.67+-0.05, 18.36 +- 0.05 18.28+-0.06. Addditional unfiltered photometry was obtained by amateur astronomers. This has been calibrated with USNO reference stars (V band), and the following magnitudes have been obtained: Jan 17.88 UT, 18.5 (0.5); Jan 19.96 UT, 18.5 (0.5); Jan 22.01 UT, 18.2 (0.2); Feb 4.10, 18.3 (0.2); Feb 4.95, 18.3 (0.2).

As the supernova magnitudes remained almost constant (within the error bars) over 18 days, we suggest that AT2016aa can be more precisely classified as a Type II-P SN.

The Asiago classification spectra are posted at this website: URL http://sngroup.oapd.inaf.it ; classification(s) was(were) made via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
