The high quality of satellite data together with the possibility to observe a star continuously for hundreds of days have made it possible to study the long-term stability of the Blazhko effect of RR Lyrae stars in detail. A preliminary analysis of the RR Lyrae star KIC6186029, observed by the Kepler space telescope, is presented. This star is of type RRab (fundamental mode pulsation) and exhibits a strong Blazhko variation. Special attention is paid to the non- repetitive nature of the Blazhko effect. The results on KIC6186029 are put into context with other known cases of changing Blazhko modulations, such as the CoRoT star 105288363 and other well-studied RR Lyrae stars for which long-term observations are available.
