Photometric transit light curve measurements are an important technique to detect and study exoplanets. It has been shown that the small-scale structures observed can be used to derive the physical properties of star spots on different stars such as their size distribution, life time distributions and magnetic cycles (Silva, 2003; Silva-Valio, et al., 2010, 2011; Valio, 2017). Multi-wavelength transit photometry (MWTP) can hence provide more precise information on the temperatures of the cold spots and the hot active regions. In this study, we will present preliminary results of our model simulations of star spot activity in terms of transit photometry.
