Simultaneous uvby photometric observations of the high amplitude [FORMULA] Sct star BS Aqr have been collected and new times of light maxima were obtained. Additionally, some [FORMULA] observations are also presented. The light curves have been analysed and the physical parameters of this star are determined. The results indicate that BS Aqr is an evolved monoperiodic [FORMULA] Sct star, with solar abundances, pulsating radially in the fundamental mode.
