Abstract

268 visual observations of the eclipsing binary VW Cephei were made during the period 28 March 1999-2February 2001. These data were used to find 21 times of minimum for this system, obtained using artificial neural networks computer programs written by A. Gaspani. The O-C graph is made using the Eclipging Binaries Minima Databvase of the Cracow Observatory. A new ephemeris is suggested: JD(min1) = 2445914.41317 (+/-0.01142) + 0.27830721 E (+/- 0.00000013.
