The Hipparcos and ASAS light curves of the recently discovered eccentric orbit binary KL CMa were analyzed by using the Wilson-Devinney program. The analysis of the light curves and all available minimum times have revealed that the system is detached, with the orbital eccentricity e = 0.131 Β± 0.007
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.
