【摘要】 1989年3月10～13日太阳耀斑事件产生了丰富的地球物理效应。本文介绍在武昌地区,耀斑期间对电离层及地磁进行多手段同步观测,并对耀斑效应进行初步分析。结果表明,出现 D 区电离陡增,F₂层虚高陡升,层描迹破坏和夜间 E 事件等明显电离层抗动现象,同时,暴时 TEC 变化剧烈,磁脉动呈现高纬特征。更多还原

【Abstract】 Interesting geophysical phenonma occurred during the solar flare event in 10～13,March,1989.Various observations have been made at Wuchang. 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.更多还原
