Four epoch lightcurves of AC Bootis, a WUMa system with W-type lightcurves, have been analysed by means of two different direct methods of solution, viz by Wilson and Wood's model respectively. The analysis of the gravity-brightening coefficients indicates that the components have convective envelopes. Moreover, we find that the hotter component is the one with lower mass, and that the degree of overcontact is small (0.06) for Wilson's model. Some discrepancies between the two methods are pointed out.
