Nine southern chemically peculiar stars brighter than the seventh visual magnitude have been observed in the uvby system. All the stars but HD 148199 are previously known light variables, although their periods were not accurate enough to phase together different kinds of observations carried out several years apart. Here we present more refined values of the period for the stars: HD 74521, HD 90044, HD 119419, HD 125630, HD 137509, HD 147010, HD 166469, and HD 170397. The star HD 148199, formerly considered constant in light, has been found to be variable in light, too, with the same period as the magnetic field.
