Della Valle, Istituto Nazionale di Astrofisica (INAF), Capodimonte Astronomical Observatory, Napoli, report on their spectroscopic observation of T Pyx with the Telescopio Nazionale Galileo (+ SARG; range 462-795 nm; resolution 57000) obtained on Apr. 14.89 UT. A preliminary analysis shows that the spectrum is dominated by Balmer, N II, and Na I emission lines. H_alpha and H_beta are flanked by blue-shifted P-Cyg profiles, and the mean expansion velocity derived from the minimum of the P-Cyg absorptions is about 1800 km/s. The measured FWHM of Balmer lines is about 1200 km/s. The Na I interstellar lines appear saturated, thus suggesting a high absorption/reddening.
