Аннотация:In 2002, 2004 and 2017 we conducted high precision CCD photometry observations of the
eclipsing binary system AS Cam. By analysis of the light curves from 1967 to 2017 (our data + data from
the literature) we obtained photometric elements of the system and found a change in the system’s orbital
eccentricity of ∆e = 0.03 ± 0.01. This change can indicate that there is a third companion in the system
in a highly inclined orbit with respect to the orbital plane of the central binary, and its gravitational
influence may cause the discrepancy between observed and theoretical apsidal motion rates of AS Cam.
