1 Otero, Sebastian Alberto Quadruple system. An eclipsing binary (Aa/Ab) with a 0.7" companion which is itself a binary (Ba/Bb). A 6.18 +/- 0.17 Earth radii planet orbits outside the 20-day orbit of the eclipsing binary consisting of an F dwarf (1.734 +/- 0.044 Solar radii, 1.528 +/- 0.087 Solar masses) and an M dwarf (0.378+/- 0.023 Solar radii, 0.408 +/- 0.024 Solar masses). Elements for the transit of the planet across the larger and brighter of the eclipsing stars are: BJD 2455074.49 + 138.317 x E. Transit duration 0.36. Depth 0.001 mag. The eclipsing binary orbit is eccentric. Elements for Min I given in the table. Elements for Min II are: BJD 2455044.3252 + 20.000244 x E. Also rotational variability of Aa with P= 2.6397 d.
