Scientific paper

New photoelectric observations of the spotted binaries UX Arietis and UV Piscium are presented and studied on the basis of a previously established technique for analyzing unevenly sampled light curves. The new data, when combined with already published observations, allowed us to reconstruct the recent evolution of the spot activity in the systems studied by means of the method described in Busso et al. (1985). The results confirm the correlations between the differential rotation, the orbital period, and the duration of spot cycles tentatively established in that paper.
