Line fits to the peak time over peak number for three phases of the SOL2022-03-30 flare shown in Fig. 4. Since the pulsation frequency is increasing significantly in time, each phase was analysed separately. Phase 1 is very well fitted by a line indicating that the timing of peaks is quasi-periodic, phases 2 and 3 are not as well fit by a line. This agrees with the error analysis presented in Table 3, where phases 2 and 3 have high variance. Between phases 1 and 3, the periodicity has increased by a factor of ∼5. This indicates that the driver of these pulsations could be different in the later stages of the flare, compared to the initial impulsive phase.
