\IBVStitletl{Timings of Minima of Eclipsing Binaries}

\IBVSauth{Diethelm, Roger} 

\IBVSinsto{Bahnhofstrasse 3, CH--4118 Rodersdorf, Switzerland} 

\begintext 

The following Table lists timings of minima of eclipsing binaries secured by CCD photometry, obtained in the second half of 2009. The given $O-C$ values generally refer to the linear elements of the 2008 electronic version of the GCVS (Samus et al., 2009), except for the cases stated in the remarks, where the determination of current elements made use of the up-to-date ASAS data ({\tt http://www.astrouw.edu.pl/asas/}) and the Lafler-Kinman algorithm of the PERANSO software ({\tt http://www.peranso.com/}). All times given are heliocentric UTC.
