Abstract:
    1RXS J201607.0+251645 is identified as an eclipsing binary. We present
    preliminary observations in the V band with the 0.6-m telescope for
    three years and extensive observations in the V and R bands with the
    0.8-m telescope for six nights, respectively. The light curve of the
    system is EB type. Five light minimum times were obtained and the
    orbital period of 0.388058d(±0.00044d) is determined.
