Comments:


1. MinII = 11.23. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

2. MinII = 12.7.

3. MinII = 10.8.

4. MinII = 13.85. D = 0.13P.

5. MinII = 12.0. D = 0.15P.

6. MinII = 14.0.

7. MinII = 12.9. D = 0.10P. The author discovered this star independently. It was earlier announced by Hoffman et al. (2008), where a twice longer period was suggested.

Remarks:
I present the discovery of seven new Eclipsing Binaries variables. A 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 from the 2MASS catalogs.
