Photoelectric light curves are presented for the Algol variable U CrB in four narrow visual and N/R passbands of the Utrecht Photometrical System, obtained in the period 1980 to 1987. The light curves confirm the presence of substantial eclipse-depth variations at all observed wavelengths. In addition, new O-C timings for primary and secondary minima are derived from these observations.
