- Аннотация: CI Cam is a known B[e] star and X-ray transient. We perform photometric and medium-resolution spectroscopic monitoring of CI Cam in the quiet state during 7 years since April 1998 outburst. We have detected orbital light variations with the period of 19.41+/-0.02 day. The modulation has an amplitude of 0.032 mag in V band. The epoch of maximum is at JD 2452200.75. We find large regular variations of the radial velocity in HeII 4686A emission line with this photometric period.
