Abstract

Photoelectric observations of the Delta Scuti star KW 207 (HD 73576) are given. In spite of the low variations, the analysis of the light curves shows at least two sighificant periodicities, which seem to be related to non-radial pulsations.

A third frequency, corresponding to the radial fundamental mode, is probably bame out by our data.
