1 Otero, Sebastian Alberto Slightly eccentric. Min II= 5.24 V at phase 0.488 (Epoch= 2456047.2669). The eclipsing system is the secondary (B) of the common proper motion double star ADS 8627, which has a separation of 5".2. The A component (V= 5.87) is triple (P= 44.41 d. and ~9 yrs.). Range given in the table is for the combined light of AB. Corrected range: 5.85 - 6.15 V.
