The study of RR Lyrae stars, performed in the framework of the Additional Programmes belonging to the exoplanetary field, will particularly benefit from such dense, long-duration monitoring. We used the CoRoT data of the new RR Lyrae variable CoRoT 101128793 (f0=2.119c/d, P=0.4719296d) to provide us with more detailed observational facts to understand the physical process behind the Blazhko phenomenon. The CoRoT data were corrected for one jump and the long term drift. We detected 79 frequencies in the light curve of CoRoT 101128793. The timeseries presented here can be used to identify the main frequency f0, its harmonics, the terms related to the Blazhko frequency f_m, two independent terms, and several combination terms. All the 79 frequencies are listed in the file table1.dat. The times of maxima are listed in the file table2.dat. Description: The file phot.dat contains 20898 datapoints. Outliers were removed and the original CoRoT measurements were corrected for two instrumental effects: a 0.032mag jump occurring at 2454369.7 and the long-term instrumental drift.
