Description Several new times of minimum light recorded with photoelectric or CCD means have been gathered for eccentric eclipsing binary V889 Aql (P = 11.1 days, e = 0.37). Its (O-C) diagram is presented and improved elements of the apsidal motion and the light-time effect are given. We found a long apsidal motion period of about 24 400 ą 2 400 years and a period of the third body about 52 ą 2 years.
