Abstract (from CDS):

We present and discuss new multi-colour photometry of the massive X-ray binary and hypergiant WRA 977=BP Cru and the luminous blue variable (LBV) HDE 269582=HV 5495 in the LMC. The light variations of WRA 977 are typical for a normal α Cyg variable and show an average quasi-period of 11.90d over a time interval of 17yr. The distance could be as large as 7.7±2.3kpc. The light variations of HDE 298582=HV 5495=MWC 112, showing a timescale of 1-2yr, have an amplitude of 0.3-0.5mag. This points to an LBV near minimum light. The colour variation is also typical for an LBV.
