We present new Johnson and Stromgren photometric observations of the delta Scuti type variable star V784 Cassiopeae. The data were obtained in three consecutive years between 1999 and 2001. The bulk of the measurements was made at the Sierra Nevada Observatory (Spain) with the 0.9m telescope equipped with a four-channel spectrograph photometer. UBV data were taken with the 0.4m telescope of Szeged Observatory (Hungary).
