N2 - The chemically peculiar (CP) stars of the upper main sequence are mainly characterized by strong overabundances of heavy elements. Two subgroups (CP2 and CP4) have strong local magnetic fields which make them interesting targets for astrophysical studies. This star group, in general, is often used for the analysis of stellar formation and evolution in the context of diffusion as well as meridional circulation. The overabundant elements in CP2/4 star atmospheres are concentrated into large spot regions that persist for decades to centuries. Periodic variations of the brightness, spectrum, and magnetic field are observed. The stars are slow rotators and it is believed that the slow rotation is owed to the strong magnetic field. Recent and future surveys that aim to obtain photometric time series are ideally suited to provide a detailed view of the stars' rotational behaviour. We present our efforts to analyze the rotational periods of CP stars and to identify new candidates in the Kepler, SuperWASP, and ASAS-3 surveys, but also in the photometric data that were extracted as valuable by-product of the STEREO satellite mission.
