Abstract

Time series of this eclipsing contact binary are reported and times of minima (ToM) of the eclipses are measured. This system has a third component. From the O-C analysis of the observed ToM and of those in the literature, the orbital parameters of the third body can be derived: the orbital period is 34.8 yr and the inclination is 11.5 .

Accepted for publication in the JAAVSO.
