1 Otero, Sebastian Alberto Double eclipsing binary. Physical nature not confirmed but the two orbital periods are close to a 3:2 ratio. Elements for system A given. Eccentric system (e= 0.18), Min II at phase 0.52. System B elements: BJD 2455968.33977 + 0.806931 x E. Amplitude given is for the combined light. System A amplitudes are 0.55 (Min I) and 0.35 (Min II) mag. System B amplitude is 0.15 mag (similar eclipses). V-mag. derived from UCAC3 and CMC14. UCAC3 position.
