In this contribution we realize a search of chromospheric activity cycles in a sample of 1048 stars of FGK spectral types. To do so, we calculate the Mount Wilson index (S MW ) for each object and then the corresponding temporal series were individually analyzed. The used spectra proceed of the extensive database of HARPS spectrograph (1001 stars), which operates in the 3.6 m ESO telescope at La Silla, Chile. Additionally, we analyzed the spectra of 47 stars taken with the REOSC spectrograph, attached to the 2.15 m Jorge Sahade telescope of CASLEO
