We have succeeded in obtaining a low-resolution spectrum (R~400) of the PNV J18193700-1907400 (in Sgr) on July 18.529 UT, using the DSS-7 spectrometer attached to the 0.28-m Schmidt-Cassegrain telescope at the OUS (Okayama Univ. of Sci.) observatory. The spectum shows emission line of H-alpha on a reddened continuum. The FWHM of H-alpha is approximately 1000 km/s. From our result, this object is thought to be a classical nova.

We have obtained a spectrum (R~400) of the Nova Sgr 2012 No.4 (CBET3166) on July 8.578 (UT), using the DSS-7 spectrometer attached to the 0.28-m Schmidt-Cassegrain telescope at the OUS Observatory. Emission lines of Balmer series, Fe II multiplets (27, 37, 38, 42, 46, 48, 49, 55 and 74), Na I D and O I (7773) can be seen in the spectrum. The FWHM of H-alpha is approximately 1800 km/s.
