| Abstract: | Several new precise times of minima, based on CCD observations, have been secured for the relatively seldom studied eclipsing
binary V865 Cyg (P=0d.365 days). Its O–C diagram was analysed and new light elements are given. We showed that there is probably no parabolic period increase in V865 Cyg.
Instead, a single abrupt period increase can be distinguished in the O–C diagram. |
