Abstract

Here we present the observations and the first light curve analysis of the short-period variable star NSVS 2983201. Using the light curve numerical modeling we find the best fitting model to be of shallow (ff=10%) contact binary configuration of mass ratio q=0.36. The light curve of the system experiences the O'Connell effect, which led to identifying a large circumpolar starspot. With a careful multi-cases analysis we search for the physical parameters of the system. We find the results obtained with the different methods to be close, but not overlapping. This system will be scheduled for the further monitoring.
