Description A brief report about a discovery of modulation in two RRab Lyrae stars XZ UMi and VX Scl is presented. The suspicion of modulation comes from our observations, but the modulation periods (41.1 d for XZ UMi and 67.3 d for VX Scl) were estimated based on the analysis of NSVS (XZ UMi) and SuperWASP data (VX Scl). Both stars show indications of period change. The peaks close to the basic pulsation frequency of VX Scl could be the signs of possible double modulation.
