1 Otero, Sebastian Alberto Quiescence around V= 2.11-2.21 (AAVSO data). The Be star is likely a blue straggler and therefore probably has an envelope-stripped or degenerate secondary (orbital period 203.5 d.) The 1.2 d. period is likely due to NRP rather than rotational modulation. (2021ApJ...915...13S)
2 GCVS Team VB A (B 11.0m, 2.2", 248deg; C 13.0m, 52.2", 348deg). In HII region S 185. X-ray source MX 0053 + 60. v sin i = 310 km/s.
