Spectroscopic observations of the peculiar variable V838 Mon during the period from the second light outburst until the fast dimming are presented. We describe high resolution high spectra obtained a day before the second light maximum and low resolution spectra covering the whole period. The temporal run of intensities and radial velocities of various lines is presented. Using D IS lines we determine the reddening distance of V838 Mon kpc, and kinematic distance kpc. We estimate that V838 Mon is slightly metal deficient but otherwise has a quite solar-like chemical composition except for enhanced abundances of Li, Ba and La.
Key words: stars: variables: general / stars: novae, cataclysmic variables / stars: individual: V838 Mon
