A preliminary analysis snows that there existed obvious ionospheric dis turbances like the sudden enhancment of D-region ionization,the sudden rise of h’F2,the breakdown of（h’-f）trace and the occurrence of night E.Strong storm time TEC variation has also observed.Geomagnetic pulsations showed some high latitude characteristics. 太刚耀斑事件 磁暴 电离层扰动 夜间 E 层 TEC 变化 地磁脉动 1991-01-01 2021-04-01 1
