7. Variable star NSVS 5781098 was discovered by the Northern Sky Variability Survey (Woźniak, 2004). Orbital period is provided in VSX catalogue and equals to 2.212737 d. Our observations allowed us to refine the period and define epoch of observations: MinI = HJD 2456124.38847 + 2.2136333× E.

Remarks:
In the previous paper (Popov et al. 2015) we presented a list of 46 newly discovered eclipsing binary stars of Algol type from KPS (Kourovka Planet Search), where detailed information on observations and data reduction is given. This paper is dedicated to the next portion of eclipsing binaries – 17 β Lyrae type stars and 29 W Ursae Majoris type stars. Also two Algol type stars are included.
