We report on post X-ray outburst (ATEL #1792) observations of the transient pulsar and Be/X-ray binary V0332+53 (BQ Cam). We obtained an optical spectrum (range 4700-7000 Angstroms, resolution 3 Angstroms) on October 22.54 UT using the 1.82-m Plaskett Telescope of the National Research Council of Canada. The spectrum shows a strong (FWHM 12 Angstroms) H-alpha emission with P-Cygni profile. The blue absorption component is shifted ~1600 km/s. The He I line at 5876 Angstroms is not apparent. Strong absorption features include the telluric B and C bands, the Na I doublet and two lines at 5779 and 6284 Angstroms.
