We present an analysis of the COnvection, ROtation and planetary Transits (CoRoT) star 105288363, a new Blazhko RR Lyrae star of type RRab (f0=1.7623d1), observed with the CoRoT spacecraft during the second long run in the direction of the Galactic Centre (LRc02, time-base 145d). The CoRoT data are characterized by an excellent time-sampling and a low noise amplitude of 0.07mmag in the 2-12d1 range and allow us to study not only the fine details of the variability of the star, but also long-term changes in the pulsation behaviour and the stability of the Blazhko cycle. We use, among other ...
