Title: Apsidal motion in BW Aqr
Keyword(s): eclipsing binary, apsidal motion
Pages: 419 -- 421

Abstract: New photoelectric and CCD observations of minima times of the detached eccentric eclipsing binary BW Aqr extended the span of its precise minima times to forty years. We used them to determine the apsidal motion rate of the binary to be dω/dt = 0.062(3)° yr^-1.
