Minima of eclipsing binaries and new ephemerides for GSC 03881-00579 and EZ Lacertae

The list below contains 163 times of minimum for 79 eclipsing binary stars (including the cataclysmic AM Her) calculated from CCD observations made by participants in the SSV-UAI Eclipsing Binaries Program. All the observatories are located in Italy; one is managed by the Physics Department of the University of Siena, while the others are privately operated. Some light curves were remotely obtained (via Internet) using the Italian and Australian telescopes of the Skylive-UAI Project, that are publicly available on the web site http://www.skylive.it. The observations were reduced following standard procedures (see next section) and the light curves were analyzed using the Kwee−van Woerden algorithm (Kwee & van Woerden,1956) to determine the times of minimum. All the times of minimum listed in this paper are heliocentric ones. It is worth noting that most of the observed stars are neglected objects.New ephemeris are given for GSC 03881-00579 and EZ Lac
