We report on a UBVRI photometry of DE CVn (RX J1326.9+4532) --- a close (60 pc) eclipsing binary with a possible white dwarf as the secondary component. The star was observed during five nights in June 2000, with the CCD camera of the 31-inch telescope of the Lowell Observatory. Data in U and I filters were taken during three of the five nights. We confirm the previously reported considerable changes of the form of the light curve from cycle to cycle and possible deep, narrow dip near the center of the primary minimum --- at least, at long wavelengths. The most important new result is a drastic increase of the depth of the primary minimum with the decreasing wavelength --- from approximately 0.1 mag. in I to approximately 1 mag in U. The significance of these results for the understanding of the system will be discussed. This project was partially supported by the NSF/REU grant AST-9820555.
