S. Fabrika, O. Sholukhova, and A. Valeev, Special Astrophysical Observatory; K. Hornoch and P. Kusnirak, Astronomical Institute, Ondrejov, Czech Republic; and W. Pietsch, MPE, obtained low-resolution spectra of 2009-10c on Oct. 9.820 UT with the Russian BTA 6-m telescope (+ SCORPIO spectral camera); spectral range 374-783 nm, resolution 1.25 nm). The nova was at magnitudes R = 17.50 ± 0.08, V = 17.69 ± 0.07, and B = 18.06 ± 0.04 on Oct. 9.806. M31N 2009-10c shows a spectrum like that of the Fe II group of novae with hydrogen and many Fe II emission lines. These lines, as well as Na I D1 and D2, are narrow with P-Cyg absorption components. Ca II H and K lines show only blueshifted absorption components. The spectrum is contaminated by strong background of the core of M31. Equivalent widths of H-beta and H-alpha lines are 3.6 and 13.5 nm; their widths (corrected for spectral resolution) are FWHM = 630 and 600 km/s, respectively. The full-width-at-zero-intensity in H-alpha is 1600 km/s. The heliocentric radial velocity of the H-alpha, H-beta, and Fe II 501.8-nm lines is -530 ± 15 km/s. The blueshifted absorption components have velocities of -1880 km/s in H-beta, -1180 km/s in Fe II 492.3-nm, -1300 km/s in Fe II 501.8-nm, and -1250 km/s in Ca II K.
