1 Otero, Sebastian Alberto Eccentric system. Min II at phase 0.60. Eclipses of the inner pair by the third component (primary eclipses) may reach V= 5.1 while the eclipses of the C star by the AB pair may be as faint as V= 4.8 based on AAVSO V data. Min II epoch = HJD 24558443.9. Elements for the ELL variations of the close pair (range V= 4.57 - 4.64) are HJD 2443141.728 + 1.5273643 d. x E.
