K. Ayani, Bisei Astronomical Observatory (BAO), Ibara, Okayama, Japan, obtained a low-resolution spectrogram (range 400-800 nm; resolution 0.5 nm at H-alpha) of this Nova in Sagittarius (TCP J18102829-2729590, CBET 4332) with the BAO 1.01-m telescope on Oct. 24.38 UT. The spectrum shows absorption lines of Balmer lines, Fe II (42), Na D, and O I 777.4. The H-alpha and O I line show P-Cyg profile. The absorption bottom of H-alpha is blueshifted by 600 km/s with respect to the emission peak. Our result confirms the report by Lucas (ATel #9658) that this TCP is a nova in early phase. The spectrum is viewable via website URL http://www.bao.city.ibara.okayama.jp/astro/2016/nova/TCP_J18102829-2729590_Oct24.png.
