Our aim was to study the light curve periodicity of the solar analogue V352CMa and in particular show that the presence or absence of periodicity in lowamplitude light curves can be modelled with the Continuous Period Search (CPS)method. We applied the CPS method to 14 years of V-band photometry of V352 CMaand obtained estimates for the mean, amplitude, period and minima of the lightcurves in the selected datasets. We also applied the Power Spectrum Method(PSM) to these datasets and compared the performance of this frequently appliedmethod to that of CPS. We detected signs of a $11.7 \pm 0.5$ year cycle in inthe mean brightness. The long-term average photometric rotation period was$7.24 \pm 0.22$ days. The lower limit for the differential rotation coefficientwould be $|k| > 0.12$, if the law of solar surface differential rotation werevalid for V352 CMa and the period changes traced this phenomenon. Signs ofstable active longitudes rotating with a period of $7.157 \pm 0.002$ days weredetected from the epochs of the light minima with the Kuiper method. CPSperformed better than the traditional PSM, because the latter always used asinusoidal model for the data even when this was clearly not the correct model.
