V2240 Cyg - interesting case of eclipsing binary with changes within O-C diagrams

Original language description

In 2010 I continued observing interesting binaries, which were chosen during the examination of the O-C gate (http://var.astro.cz/ocgate) on the server of Variable Star and Exoplanet section of Czech Astronomical Society. The changes in the appearance of the O-C diagrams imply that the mentioned changes could be caused by the following mechanisms: 1) the occurrence of the third star, 2) the system of eclipsing binaries with an eccentric orbit, 3) apsidal motion, 4) there is a combination of all those effects mentioned above.
