We report that an optical spectrogram of PSN J07484410+5436405 (range 340-820 nm; resolution 1.3 nm), obtained on March 31.02 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC), shows it to be a type-Ia supernova. Adopting for the host galaxy (NGC 2446) a radial velocity of 5668 km/s (Theureau et al. 1998, A&AS 130, 333, via NED), a good match is found with several type-Ia supernovae few days before B-band maximum light. An expansion velocity of about 11800 km/s is derived from the minimum of the Si II 635-nm line.
