Comments:
1. MinII = 14.35, D = 0.07P. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

2. MinII = 11.95, D = 0.10P. X-ray source 1RXS J005217.8+351551 .

3. MinII = 12.9, D = 0.10P.

4. MinII = 12.35, D = 0.13P. X-ray source 1RXS J010537.3+364857. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

5. MinII = 11.5, D = 0.10P. X-ray source 1RXS J011647.3+341816. The RS-type activity in maximum brightness.

6. MinII = 11.65, D = 0.11P. Identification with the X-ray source 1RXS J013521.5+374605 is possible.

7. MinII = 11.15, D = 0.16P.

8. Minimum (eclipsing) = 12.75, D = 0.05P. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

9. D = 0.06P. The period value is based on the NSVS data and our additional visual observations. (29 estimates, JD2454303-2454365. Comparison stars: TYC 1778 00716 1 and TYC 1778 01480 1; magnitudes of the comparison stars were taken from the Tycho-2 catalog. Telescope: 15-cm reflector.) Mag (vis) = 11.8 - 12.5. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

10. D = 0.11P.

Remarks:
I present the discovery of 10 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.
