28cm (F10) + DSS-7 (R~400)
Exposure time 30sec x 8

We have obtained a spectrum (R~400) of the recurrent nova T Pyxidis on April 16.528 (UT), using the DSS-7 spectrometer attached to the 0.28-m Schmidt-Cassegrain telescope at the Tanabe Personal Observatory (Okayama Univ. of Sci. team). Emission lines of Balmer series, He I (5016, 5876, 6678), N II (4489, 4655, 5001, 5679, 5938, 6482), N III (4640) and O I (7774) are seen on the our spectrum. The FWHM of H_alpha is approximately 1500 km/s.
