1 Otero, Sebastian Alberto Secondary period 0.0744 d. Slightly different periods depending on wavelength. The star is 21" away from the red star GSC 08330-02735 (a possible blended double with combined V= 13.8) and 28" away from the possibly slightly variable Be star SS 279 (V= 12.02 - 12.22). Magnitudes were derived using SS 279 as the comparison star with mean V= 12.15 from APASS (two observations). This star is not HD 328864 as stated in some publications. HD 328864 is NGC 6200 5.
