Comments:


1. HDE 279788 = BD+38 891 = 1RXS J042638.5+384458. The star's spectroscopy was reported by Li & Hu (1998). From its spectrum, this can be a weak-lined T Tauri star.

2. 1RXS J090347.3+121837.

3. BD+38 2188 = 1RXS J105305.8+381333.

4. 1RXS J144952.3+420615.

5. 1RXS J145502.5+144210. A twice longer period (3.4906 days) with an EB-like phased light curve is possible.

6. 1RXS J191302.4+443629.

7. HD 226195 = BD+40 3908 = 1RXS J195125.1+404405. The period reported is only one of several possibilities.

8. BD+43 3754 = 1RXS J205257.8+440716.

Remarks:
We report variability discovery for eight stars found in the public data release from the Northern Sky Variablity Survey (NSVS; Wozniak et al., 2004; see also http://skydot.lanl/gov/nsvs). A periodicity test was performed using the Lafler - Kinman algorithm implemented in the Peranso software (Husar, 2006).

Acknowlegdements: I would like to thank Dr. Y. Beletsky for his assistance.
