Scientific paper

Photoelectric observations of the W UMa variable ST Ind are analyzed which were obtained at the European Southern Observatory in the course of a program to monitor light curve fluctuations. Photometric and geometric elements of ST Ind are derived. The observations show the presence of a periodic fluctuation in certain parts of the light curve which may be explained by the precessional motion of the rotation axis of the brighter component.
