Differential Stromgren uvby photometric observations from the Four College Automated Photoelectric Telescope refine the rotational periods and define the shapes of the light curves of four magnetic Chemically Peculiar stars. HD 32633 () exhibits an in-phase variability with asymmetrically shaped light curves. 25 Sex () has a complex variability with the v , b , and y light variability crudely in phase, but quite different from that of u . HR 7224 () shows in-phase variability with two nearly equal secondary minima. HD 200311 (), which was previous thought to be a long period variable, is found to be a modest photometric variable.
