Abstract: We present 132 h of new time-series photometric observations of the delta Scuti star CD-34 7599 acquired during 86 nights from 1993 to 1996 to study its frequency and amplitude variations. By using all published observations we demonstrate that the three dominating pulsation modes of the star can change their photometric amplitudes within one month at certain times, while the amplitudes can remain constant within the measurement errors at other times. CD-24 7599 also exhibits frequency variations, which do not show any correspondence between the different modes.
