The Solar Flare Catalog with GECAM

The GECAM (Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor) mission has significantly enhanced the detection and analysis of high-energy astrophysical phenomena, particularly solar flares. This study presents a comprehensive catalog of solar flares observed by GECAM, systematically documenting 774 high-energy flare events from January 2021 through December 2024. Through a rigorous three-stage screening process—including spatial filtering (<20° deviation from the solar center), spectral-temporal analysis, and cross-validation with GOES satellite data—we precisely identified and classified flares across different intensity levels. The catalog provides detailed records of flare timing, spatial distribution, energy spectra, and key temporal parameters (e.g., rise time, decay time, and duration). These findings not only validate the critical role of high-energy observations in deciphering solar dynamics but also establish GECAM as an indispensable tool for solar physics and multi-messenger astrophysical research.
