\IBVSabs{We present several Photoelectric minima observations of}
\IBVSabs{some eccentric eclipsing binaries.}

\IBVSEobs{30-cm, 35-cm and 40-cm Meade and 48-cm Cassegrain telescopes at Ege University Observatory Research and Application Center.} 

\IBVSEdet{SSP-5 photoelectric photometer attached to 30 and 35-cm telescopes, high-speed three-channel Vilnius photometer attached to 48-cm telescope and Apogee 2048x2048 CCD camera attached to 40-cm telescope.}

\IBVSEred{Reduced differential magnitudes, in the sense of variable minus comparison, were obtained using the procedures outlined in Hardie (1962).}

\IBVSEmethod{ The minima times were calculated using the method of Kwee \& van Woerden (1956).}
