Strömgren photometry of the δ Scuti star 67 UMa

We present preliminary results derived from the data obtained during five observing campaigns in 2001, 2003, 2004, 2006 and 2007, of the δ Set-type variable star 67 UMa, at Sierra Nevada Observatory, Spain. The analysis of the data was performed by means of the Fourier Transform method, and results are shown. The intrinsic b-y, m1, c1 values are derived and the physical parameters are determined.
