Luboš Brát wrote at 23. 3. 2011 According to BVRI photometry performed by K. Hoňková and J. Juryšek, the light curve has amplitude 0,05 mag in I band and almost twice larger amplitude in B band. Together with slightly asymetric shape of light curve, it proves that CU CVn is not an eclipsing binary, but the pulsating one (probably delta Scuti).
