Detection of planetary transits holds the greatest promise for the search of terrestrial planets. However intrinsic stellar variability can mask real transits or lead to 'false' planet transit detections. Understanding the origin of stellar variability can help to estimate the minimum sizes of planets detectable with this technique around different types of stars and to identify the best wavelength range for such measurements. The only star for which data with sufficient photometric accuracy and temporal sampling exist is the Sun. We analyze and model solar variability on timescales relevant for planetary transits (hours to several days) using a variety of components such as granulation network (supergranulation) faculae and sunspots. This study extends our successful work to model solar irradiance variations on days to years timescales (Fligge et al. 2000; Krivova et al. 2003).
