Note on CI Cam (Re: XTE J0421+560) More information on the known variable star, CI Cam, which is located within the new error circle of XTE J0421+560. Our library has fortunately received the original article on CI Cam: Odessa Astronomical Publications, 7, part 1, p. 76 by A. S. Miroshnichenko (anat@gaoran.spb.su). According to this literature, spectroscopy of the B[e] star MWC 84 = CI Cam revealed absorption features typical for late-type stars. Photometric observations revealed 11.7-d periodicity with an amplitude of 0.3 mag. The best fit for the SED is B0V + G8II plus a dense gas and dust shell. Hope this information would help for further investigations. Regards, Taichi Kato
