Comments:


1. In the light curve, our eye estimates of the variable's brightness on the red USNO archive images were reduced to the V photometric system of the ASAS-3 survey using V-R=1.0.

3. MinII=11.63, D=0.15P

6. MinII=14.5

Remarks:
In our work on the improvement of the coordinates for all stars in the NSV catalog, we succeeded in studying seven variable stars. We could find and study the variables thanks to the publicly available electronic archives of CCD observations of the ASAS-3 (Pojmanski, 2002) and ROTSE1/NSVS (Wozniak et al., 2004) surveys. We recovered the variables NSV 05769 and 05918 suspected by Luyten (1933) who had published only the variability ranges and very rough coordinates. The candidates were found using the US Naval Observatory Image Archive (http://www.nofs.navy.mil/data/fchpix/).

Thanks are due to Dr. S.V. Antipin and Dr. L.N. Berdnikov for their assistance during the preparation of the paper.
