		| Abstract: | We present an analysis of  photoelectric UBVRC observations
 of FG Ser. The orbital period of the binary was improved to
 629.4 days. We  discuss the color changes of the object and
 reconstruct the spectral energy distribution (SED) of FG Ser at
 the maximum of its optical brightness, and derive its physical
 parameters. |
