We present a study of the high-resolution ( 000) optical spectrum of the
B[e] supergiant CI Cam obtained 4 years after its all-wavelength outburst.
The profiles of most of the emission lines show a triple-peaked structure,
an effect previously not observed. The Na i D-lines clearly have 2
interstellar absorption components, suggesting that the system is most
probably located within the Perseus arm at a distance of ≤3 kpc.
Uncertainties of the distance toward the object, its luminosity, and
physical parameters of the circumstellar disk are discussed.
Simple observational tests are suggested to clarify these issues.
