CCD (V) light curve of the EW-type eclipsing variable DF CVn was obtained during seven nights in April-May, 2004. With our data we were able to determine 4 new times of minimum light. The light curve appears to exhibit a typical O'Connell effect, with Maximum I brighter than Maximum II by 0.013 mag.
