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.
