摘要: 太阳耀斑是太阳大气中最强烈的爆发现象,能够释放大量能量并产生各种波长的电磁辐射。研究太阳耀斑对于理解太阳活动、空间天气预报以及保护地球空间环境至关重要。本数据集利用"夸父一号"卫星采集的全日面图像数据,通过一套自主研发的太阳耀斑自动识别和关键参数提取算法,系统记录了2024年全年在莱曼阿尔法波段观测到的太阳耀斑事件。该算法能够有效避免宇宙线、粒子暴等事件的干扰,可以对不同强度级别的耀斑进行识别,并能对日面上同时发生的多个耀斑进行分别识别和追踪。数据集收录了耀斑的起始和结束时间、持续时间、发生位置、显著性等关键参数,包含耀斑识别过程记录文档、耀斑事件列表、耀斑峰值时刻快视图像和耀斑区域电影动画等数据产品。本数据集可为太阳物理学研究、空间天气预报以及相关领域提供重要的科学数据支持。Abstract: 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 full-disk solar images collected by the "Kuafu-1" 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.
