Аннотация (русский):
We present the first results of our work on creating a catalogue of solar flares observed with the Siberian Radioheliograph (SRH). A technique to find possible solar flare events has been developed. This technique is based on the analysis of the derivatives of temporal profiles and allows one to identify the start, peak, and end moments of events of various intensities. We tested this technique using time profiles of solar soft X-ray emission, which is currently the main indicator of solar flares. The results of the testing of the technique has shown good detection of flare events for one-dimensional data. As the SRH is a multi-frequency instrument, the technique has been improved by adding the ability to automatically identify events based on the simultaneous response at different frequencies.The method was tested to detect solar flares observed with the SRH in the 3–24 GHz range. In total, we revealed about 600 events of various importance classes during the summer months of 2023 and about 300 solar flares occurred in May 2024. The developed software allows one not only to reveal the onset and end of a flare but also provides dynamic spectra that can be used for further analysis of the event.
