    <description descriptionType="Abstract">&lt;p&gt;Rotational modulation due to dark spots co-rotating with the stellar surface allows us to constrain rotation and magnetic properties of solar-like stars. The long-term observations collected by &lt;em&gt;Kepler&lt;/em&gt; (and those that will be collected by PLATO) are preferred for a better characterization of magnetic activity. In this work, we investigate the temporal variability of the photometric magnetic activity proxy S&lt;sub&gt;ph&lt;/sub&gt;, as well as the characteristic timescale of active-regions in solar-like stars.&lt;/p&gt;</description>
