Remarks:
We presents the discovery of 3 new variables. Our search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS, Wozniak et al., 2004, also see http://skydot.lanl.gov/nsvs). These observations were analyzed using the period-search software developed by Dr. V.P. Goranskij for Windows environment. The coordinates were drawn either from the Tycho-2 or 2MASS catalogs. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis. In the cases of GSC 4550-01410 and GSC 4550-00626, the use of these data considerably increases the number of available observations without deteriorating quality and allows us to determine the periods more accurately. The variables 1 and 2 were discovered by N. Biyalieva, the last one - by A. Khruslov.
