The nova sgr 2012 No4 was discovered by Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyak, Japan. CBAT

I have obtained an echelle spectrum (R~11000) of the Nova Sgr 2012 No.4 (CBET3166) on July 8.872 (UT), using the eshell spectrometer attached to the 0.35-m Schmidt-Cassegrain telescope at the fontcaude observatory, France. Emission lines of Balmer series, Fe II , Na I D and O I (7773) can be seen in the spectrum.  At the time of exposure, the nova sgr 2012 No4 was at magV 7.8 (TAROT).

Exposure time was 2H, calibration was made on a thorium argon calibration lamp spectra. Standard procedures were applied (flat field correction, dark current and offset subtraction) and spectrum reduction was made under Audela package with an instrumental response calculated on a spectra of Vega. Some extracts can be seen below.
