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
