From an analysis of the WASP lightcurve together with V-band and I_C-band photometry of the eclipse and a spectroscopic orbit for the A-type star we estimate that the companion star has a mass of (0.23+-0.03)Msun and a radius of (0.33+-0.01)Rsun, assuming that the A-type star is a main-sequence star with the metalicity appropriate for a thick-disk star.
