Comments:

1. M-m = 0.20 P.

2. M-m = 0.25 P.

3. M-m = 0.15 P.

5. M-m = 0.35 P. A one-day alias period, 0.27596 d, is not excluded.

6. M-m = 0.11 P.

7. M-m = 0.3: P.

8. M-m = 0.15 P. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis. In the case of GSC 4182-00914, the use of these data considerably increases the number of available observations without deteriorating quality and allows us to determine the period more accurately.

9. M-m = 0.1 P.

10. M-m = 0.2 P.

Remarks:
I present the discovery of 10 new RR Lyrae variables. 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 from the 2MASS catalog.
