Photoelectric and CCD photometry of eclipsing contact binaries: UV Lyn, FU Dra and AH Aur
New photoelectric BV and CCD BVR observations of the eclipsing contactbinary systems UV Lyn, FU Dra and AH Aur obtained from January 2000 toApril 2001 are presented and analyzed. Photometric elements determinedfrom our light curves combined with published spectroscopic elementsyielded the absolute parameters of the systems. Analysis of the (O-C)diagram of AH Aur revealed fast period changes. The correct ephemerisfor the primary minimum was determined. The evolutionary status of allthree systems is discussed.
