Standard Dataset of Lyman-Alpha Solar Flare Events

Solar flares are the most intense eruptive phenomena in the solar atmosphere, releasing large amounts of energy and producing electromagnetic radiation across various wavelengths. Research on solar flares is crucial for understanding solar activity, space weather forecasting, and protecting the Earth’s space environment. Based on the full-disk solar images in the Lyman-alpha waveband (121.6±7.5) nm collected by the Solar Disk Imager (SDI) carried by the China’s ASO-S satellite, this dataset systematically records solar flare events observed in the Lyman-alpha band throughout 2024 using an independently developed automatic solar flare identification and key parameter extraction algorithm. This algorithm effectively avoids interference from cosmic rays and particle storms, identifies flares of different intensity levels, and can separately identify and track multiple flares occurring simultaneously on the solar disk. The dataset includes key parameters such as flare start and end times, duration, location, and significance, and contains data products including flare identification process documentation, flare event lists, quick-view images of flares at peak moments, and movies of flare regions. This dataset provides important scientific data support for solar physics research, space weather forecasting, and related fields.
