We report optical spectroscopic observations of the 2016 outburst of the recurrent nova M31N 2008-12a (ATel #9848, #9852, #9853, #9857, #9861, #9864) on December 13.58UT and 14.55UT. The spectra were obtained using the HFOSC instrument mounted on the 2m Himalayan Chandra Telescope (HCT) of the Indian Astronomical Observatory, Hanle, India, in the 380-800nm wavelength range. The spectra show hydrogen Balmer lines, and appear similar to the previous outbursts (Darnley et al. 2016, ApJ (accepted): ArXiv:1607.08082). The FWHM velocity of the H-alpha line was measured to be ~2900km/s on Dec 13.58 and ~2700km/s on Dec 14.55. Observations with the HCT are continuing.
