Comments:


1. 1RXS J003633.1+430550. B-V = +1.23.

2. 1RXS J003712.3+441303. B-V = +0.8.

3. 1RXS J004021.5+434327. B-V = +1.2. NSVS 3784810 is a blend of two bright stars; as a result, the NSVS amplitude is small. The X-ray source is closer to the eastern component.

4. 1RXS J082713.6+412830. B-V = +1.0.

Remarks:
I present the discovery of four new RS CVn stars. 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 Peranso (http://users.skynet.be/fa079980/peranso/index.htm).
