Similar as in Fig. 21, but for star CoRoT 102904910 (star No 22) in the IR1. The outburst is very short and results are only indicative. Four phases are found: (a) precursor phase ↔, (b) brightening phase ↔, (c) relaxation phase ↔, (d) relative quiescent phase ↔. Four groups are present at 1.92, 3.85, 5.75 and 7.75 c d⁻¹. The amplitude of the group at 3.85 c d⁻¹ is very high during the brightening phase.
