Abstract:

Six years of new photometry of V 1794 Cyg is combined with the previously published data. These data are processed into two decades of homogeneous standard Johnson UBVRI photometry, which contains 1207, 1837, 1927, 867 and 75 observations in U, B, V, R and I, respectively.

Key words: stars: individual: V 1794 Cyg (HD 199178); variables -- techniques: photometric
