Scientific paper

New photoelectric BV and CCD BVR observations of the eclipsing contact binary systems UV Lyn, FU Dra and AH Aur obtained from January 2000 to April 2001 are presented and analyzed. Photometric elements determined from our light curves combined with published spectroscopic elements yielded the absolute parameters of the systems. Analysis of the (O-C) diagram of AH Aur revealed fast period changes. The correct ephemeris for the primary minimum was determined. The evolutionary status of all three systems is discussed.
