We report optical spectroscopic observations of the recent eruption of the Recurrent Nova M31N 2008-12a [00 45 28.80 +41 54 10.1] (see ATels #12177, #12179, #12181, #12182, #12189, #12190). Spectra were obtained on November 07.81 and 08.59 UT using the HFOSC instrument on the 2m Himalayan Chandra Telescope (HCT). The spectra, obtained in the 380-800nm region, show Hydrogen Balmer lines with FWHM velocity of ~ 3500 km/s for Hα and ~ 2000 km/s for Hβ. Lines due to He I (5876, 6678, 7065), N III (4638) are also present. The spectra are similar to those of the previous outbursts (e.g. Henze et al. 2018, ApJ, 857, 68; Darnley et al. 2016, ApJ, 833, 149).
Observations from HCT will be continued.
We thank the IAO observers for sparing time to carry out the ToO observations.
