Comments:


1. J–K = 1.119 (2MASS). Probable cycles: 25 d and 150 d.

2. J–K = 1.031 (2MASS).

3. J–K = 1.297 (2MASS). Optically double system. UCAC4 556-068879 is in ~3".

4. J–K = 1.197 (2MASS). IRAS R18250+2247.

5. J–K = 1.226 (2MASS). IRAS Z18330+1837.

Remarks:
I present new variables discovered by data mining. My search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS, Woźniak et al. 2004). These observations were analyzed using the period-search software developed by Dr. V.P. Goranskij for Windows environment and adjusted in the VS-COMPAS group for discovering variables by data mining (http://vs-compas.belastro.net/tools).

Acknowledgements: I would like to thank I.S. Brykhanov for helpful discussion. I thank I. Adamin, A. Prokopovich, and A. Tkachenko for access to software and data used for my research.
