1 Otero, Sebastian Alberto Spectroscopic period 1.225155 d. in 1979RMxAA...4..297H. The TESS folded light curve with the orbital period shows only one maximum and minimum so it is likely a reflection binary. Classified as SPB with P= 1.22508 d. in the Gaia DR3 variability catalog (2022yCat.1358....0G).
