Comments:
1. MinII = 11.8. D = 0.15 P.

2. MinII = 13.7. D = 0.12 P. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis. The use of these data considerably increases the number of available observations without deteriorating quality and allows us to determine the period more accurately.

3. MinII = 13.8. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis. The use of these data considerably increases the number of available observations without deteriorating quality and allows us to determine the period more accurately.

4. MinII = 12.3. D = 0.18 P.

5. MinII = 13.1. D = 0.12 P.

6. MinII = 12.75. D = 0.12 P. B-V = 1.410.

7. MinII = 10.18. Eccentric binary system, the phase of MinII is 0.44 P.

8. MinII = 13.5. D = 0.10 P.

9. MinII = 12.55. D = 0.10 P.

10. MinII >= 11.25. D = 0.10 P.

11. MinII = 13.75. D = 0.10 P. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis. The use of these data considerably increases the number of available observations without deteriorating quality and allows us to determine the period more accurately.

Remarks:
I present the discovery of 11 new Algol-type eclipsing binaries (EA). 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.
