Comments:

1. M-m = 0.25:P. J-H = 0.238 (2MASS).

2. M-m = 0.22P. J-H = 0.221 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

3. M-m = 0.18P. J-H = 0.374 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

4. M-m = 0.38P. J-H = 0.123 (2MASS), B-V = 0.049 (Tycho2).

5. M-m = 0.23P. J-H = 0.299 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

6. M-m = 0.35:P. J-H = 0.174 (2MASS).

7. M-m = 0.32P. J-H = 0.126 (2MASS).

8. M-m = 0.18P . J-H = 0.293 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

Remarks:
I present the discovery of eight 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 either from the Tycho-2 or from the 2MASS catalogs.
