The photometric behaviour of 21 Ap stars has been analyzed from observations obtained in the Geneva system. Variability has been detected for 9 Ap stars, as well as for a star which initially was a comparison star. Preliminary values for the periods are presented as well as an analytical description of the light curves.
Key words: stars: chemically peculiar; variable
based on observations made at the Swiss telescope of the European Southern Observatory, La Silla, Chile.
