Eclipsing binaries, Cygnus to Hydra, in 1972-1985
Photoelectric and visual observations of 40 known and suspectedeclipsing binaries are discussed. Revised light elements are derived forthree systems. The period of V450 Her should possibly be doubled fromabout 0.9d to about 1.8d. Secondary minimum has been detected in DI Hya.

UBV photometry of stars whose positions are accurately known.
Photometric indices V, B-V, and U-B were measured for about 560 stars ofthe AGK3R and NPZT catalogs between BD declinations 11 deg and 23 deg,using the 40-cm Cassegrain telescope of the Kvistaberg Observatory fromApril 1986 to May 1987. The observation procedure and the reductiontechnique were the same as in the earlier papers of this series by Oja(1984, 1985, 1986, and 1987). The mean errors were calculated from theinternal consistency of the data. The accuracy was found to be the sameas for the earlier parts of the survey.

Variable light curve of the eclipsing binary IU Aurigae
Results of observations of IU Aur are presented. The increases inlight-curve amplitude and the periodic term at times of minima, found inan earlier paper, are confirmed. It is shown that in the eclipsingsystems with varying inclination (due to orbital precession caused by athird body), it is possible to determine differences between equatorialand polar limb darkening. Some other effects of a third body in thesystem are discussed.
