Comments:


1. MinII = 14.7. The ROTSE data with photometric correction flags were kept for the analysis.

2. MinII = 13.45.

3. J–H = 0.434 (2MASS). 1RXS J044210.0+820616.

4. B–V = 0.433 (Tycho2), J–H = 0.164 (2MASS). The period ratio of the first overtone and fundamental modes is P1/P0 = 0.7666. The star has a faint close companion GSC 4342-00692. The ROTSE data with photometric correction flags were kept for the analysis.

5. MinII = 14.35. The star has a faint close companion 2MASS 06340683+7631274. Perhaps a blend of the two stars is in the NSVS. The variability amplitude can be underestimated.

6. MinII = 15.0. The ROTSE data with photometric correction flags were kept for the analysis.

7. MinII = 13.1.

8. MinII = 12.9.

9. MinII = 15.2.

10. MinII = 13.18. Period 0.24432 days is not excluded. 1RXS J132056.1+683954.

11. J–H = 0.552 (2MASS). 1RXS J132230.2+702035 . The variability amplitude changes with time.

12. MinII = 13.25, D = 0.07 P. 1RXP J132257.9+652507, 1WGA J1322.9+6525.

13. MinII = 14.7. Type RRC is not excluded, with the elements: JD(max) = 2451400.606 + 0.36027 × E. J–H = 0.244 (2MASS).

14. MinII = 14.65.

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

16. BD+67 803. MinII = 9.85. Period 0.21157 days is not excluded.

17. D = 0.14 P.

18. MinII = 12.75. D = 0.13 P.

19. MinII = 13.05.

20. M–m = 0.40 P. J–H = 0.234 (2MASS).

21. MinII = 13.8. The ROTSE data with photometric correction flags were kept for the analysis.

22. MinII = 14.0. The ROTSE data with photometric correction flags were kept for the analysis.

23. J–H = 0.587 (2MASS). The color index B–V = 1.798 (Tycho2) is probably wrong.

24. MinII = 12.55. A companion, GSC 3868-00445, can somewhat influence the NSVS photometry.

25. MinII = 13.75. The star has a faint close companion 2MASS 15311122+7026546.

26. MinII = 15.6.

27. Period 0.37323 days is not excluded. 1RXS J153850.8+690048. B–V = 1.468 (Tycho2), J–H = 0.529 (2MASS).

28. B–V = 0.142 (Tycho2), J–H = 0.506 (2MASS). The ROTSE data with photometric correction flags were kept for the analysis.

29. B–V = 0.991 (Tycho2), J–H = 0.602 (2MASS). 1RXS J154346.4+701828.

30. MinII = 14.2. The star has a faint close companion 2MASS 15451752+6549551.

31. B–V = 0.266 (Tycho2), J–H = 0.121 (2MASS).

32. B–V = 0.790 (Tycho2), J–H = 0.432 (2MASS). 1RXS J160820.6+700353.

33. B–V = 1.606 (Tycho2), J–H = 0.907 (2MASS). IRAS F16120+7054. The ROTSE data with photometric correction flags were kept for the analysis.

34. MinII = 12.27. Type ELL is not excluded.

35. J–H = 0.587 (2MASS).

36. J–H = 0.871 (2MASS).

37. MinII = 14.9.

38. All observations with the errors > 0.05m were rejected. Along with the light curves, we reproduce the power spectra (Deeming's method) for each of the two NSVS entries. The frequency corresponding to a twice shorter period is labeled "f". J–H = 0.172 (2MASS).

39. MinII = 14.5. (14.1–14.8 in the V band from the ASAS data).

40. MinII = 14.1. (13.75–14.15, MinII = 14.0 in the R band).

41. MinII = 13.95. (13.5–14.2, MinII = 14.0 in the R band).

42. MinII = 14.05. (13.5–13.95, MinII = 13.75 in the V band from the ASAS data). The ROTSE data with photometric correction flags were kept for the analysis.

43. MinII = 13.30. (13.15–13.5:, MinII = 13.35 in the R band).

Remarks:
I present a discovery of 43 new variable stars. My search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS, Wozniak et al. 2004). They were appended, when possible, with ASAS-3 data (Pojmanski 2002). 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.
