Turatto, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that an optical spectrogram (range 340-800 nm; resolution 1.2 nm) of PSN J10483231+2635179, obtained on Dec. 18.18 UT with the Asiago 182-cm Copernico Telescope (+ AFOSC, equipped with a new Andor IKON L936 CCD with a higher quantum efficiency both in the UV and in the NIR) under the Asiago Transient Classification Program (Tomasella et al. 2014, AN 335, 841), shows that this is a type-Ia supernova. Adopting for the host galaxy (UCG 5912) a heliocentric radial velocity of 6295 km/s (RC3; via NED), a good match is found with several type-Ia supernovae few days before B-band maximum light. An expansion velocity of about 14400 km/s is derived from the minimum of the Si II 635-nm line. Classification was done with GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
