71. J–K = 0.503 (2MASS), B–V = 0.379 (Tycho2). From ROTSE-I/NSVS data, 12m.25–12m.35 in the R band. According to NSVS data, the light elements are: JD(min) 2451500.5 + 2.413×E. The ROTSE data with photometric correction flags were kept for the analysis.

72. B–V = 0.970 (Tycho2), J–K = 0.728 (2MASS). From 1SWASP data, 11m.7–11m.95 (1SWASP). The ROTSE data with photometric correction flags were kept for the analysis.

73. MinII = 13m.16 (1SWASPmag). From CSS data, 12m.65–12m.85, MinII = 12m.85 (CV); from ROTSE-I/NSVS data, 12m.94–13m.08, MinII = 13m.08 in the R band. According to NSVS data, the light elements are: JD(min) 2451500.660 + 0.34532×E.

74. The variability of GSC 3422-01397 was independently discovered by Palaversa et al. (2013) in the LINEAR Survey. MinII = 14m.97 (CV). Combined brightness of two stars, GSC 3422-01397 (=var) and GSC 3422-01612, was measured in the NSVS and 1SWASP, the amplitudes are somewhat underestimated.

75. MinII = 12m.30 (1SWASPmag). From ROTSE-I/NSVS data, 12m.28–12m.41, MinII = 12m.38 in the R band.

76. J–K = 0.686 (2MASS). Type EB is not excluded. From ROTSE-I/NSVS data, 12m.55–12m.7, MinII = 12m.65 or 12m.68–12m.8, MinII = 12m.8 in the R band. The ROTSE data with photometric correction flags were kept for the analysis.

Remarks:
I present a discovery of 76 new variable stars. My search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS , Woźniak et al. 2004). Besides, to improve classification and light elements, I analyzed all available observations of these stars from the Catalina Surveys (Drake et al. 2009) and SuperWASP (Butters et al. 2010). The sky area with RA between 07h 11m and 08h 45m, Dec between +40° and +52° was searched.

Many of the variables presented in this paper are close visual pairs that cannot be separated with the low resolution of the surveys like NSVS or 1SWASP. Data from the Catalina surveys, which have resolution as good as 12 arcseconds, provide a possibility to solve this problem. In these cases, combined brightness of several stars was measured in the NSVS and 1SWASP, so that the resulting amplitude is underestimated and the variable's mean brightness appears much higher than in reality; for this reason, only CV (Catalina) magnitudes are tabulated for such stars.

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.

The SuperWASP observations are available as FITS tables, which were converted into ASCII tables using the OMC2ASCII program as described by Sokolovsky (2007).
