Comments:


6. Likely Blazhko Effect.

Remarks:
We present the discovery of ten RR Lyrae variables. They were found in a search for new variables in the OGLE II Photometric Database (Szymanski 2005, Udalski et al. 1997). Suitable parameters (e.g. Isig>0.1, Imederr< Isig) were used in the OGLE Photometry Database Query Page (http://ogledb.astrouw.edu.pl/~ogle/photdb/) for stars in the Galactic Disk. Period analysis was made with the software AVE (GEA).
