Comments:


1. MinII = 13.78. The secondary minimum is away from the phase 0.5, indicating an eccentric binary. MinII – MinI = 0.525P. The ROTSE data with photometric correction flags were kept for the analysis.

2. MinII = 13.65. D = 0.12P. The ROTSE data with photometric correction flags were kept for the analysis.

3. MinII = 14.0.

4. MinII = 13.95. The ROTSE data with photometric correction flags were kept for the analysis.

5. MinII = 14.9. The ROTSE data with photometric correction flags were kept for the analysis.

6. MinII = 12.7. There is a fainter close companion GSC 4211-00231. The ROTSE data with photometric correction flags were kept for the analysis.

7. MinII = 14.1. The ROTSE data with photometric correction flags were kept for the analysis.

8. MinII = 14.2. The ROTSE data with photometric correction flags were kept for the analysis.

Remarks:
I present the discovery of eight new eclipsing binaries. My search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS, Wozniak et al. 2004). These observations were analyzed using the period-search software developed by Dr. V.P. Goranskij for Windows environment. The coordinates were drawn from the 2MASS catalog.
