- Аннотация: We present the results of the analysis of quasiperiodic pulsations of chromospheric emission from three solar flares.The study is based on observational data obtained with two ground-based spectrographs: the Multichannel FlareSpectrograph and the Horizontal-Sonnen-Forschungs-Anlage 2 of the Ondřejov Observatory (Astronomical Instituteof the Czech Academy of Sciences). The analysis of the power spectra of time profiles obtained using both spectrogramsand filtergrams is carried out. The revealed periods were compared with the results of periodicity analysis in the X-rayand microwave ranges. For those events where the duration of observations allowed, a period close to 5 minutes wasfound from both the data of chromospheric observations and the data obtained in the X-ray and microwave ranges. Wealso found the periods about 1.4–1.8 and 2–3 minutes, which simultaneously appeared in all studied ranges.
