	abstract = {Seven new precise times of minimum light have been gathered for the triple eccentric eclipsing binary YY Sgr (P = 2<SUP>d</SUP>.63, e = 0.16). Its O--C diagram is presented and improved elements of the apsidal motion and the light-time effect are given. We found a new short period of the third body of about 18.5 years in an eccentric orbit (e <SUB>3</SUB> ≃ 0.4).},
