Abstract: After the completion of data taking at HERA-2, a large data set is at hand to study the photoproduction of charm and beauty quarks in ep collisions. New measurements of charm production based on D^* meson tagging and beauty production based on muon and electron reconstruction test perturbative QCD calculations with improved accuracy. In general, QCD calculations at NLO describe the data well. The scale uncertainties are, however, large and dominate over the experimental uncertainties, calling for more precise calculations.
