摘要：1966 年 8 月 28 日 1522 UT 发生了一次估计重要性为 3B 的大规模太阳耀斑。这次耀斑对分布在整个阳光照射半球的约 36 个站获得的磁力图产生了显着的干扰。在这些磁力图上观察到的许多主要结构具有显着的同时性，并且与观察到的 SID 事件密切相关。尝试对这些记录进行详细的时间分析，并从观察到的耀斑开始开始多次计算等效电离层电流系统。该分析与耀斑的光谱历史一致，其中随着耀斑接近最大值，X 射线辐射逐渐变得更强。分析表明发电机区域的全球风系统存在垂直变化，导致该区域上部的电流逆转。这表明 SFE 的时间分析代表了检查该地区风的垂直结构的新工具。
Abstract : At 1522 UT on August 28, 1966 there occurred a massive solar flare of estimated importance 3B. This flare produced significant disturbances on the magnetograms obtained from some 36 stations distributed throughout the sunlit hemisphere. Much of the major structure observed on these magnetograms occurred with significant simultaneity and correlated well with observed SID events. A detailed time analysis of these records was attempted and equivalent ionospheric current systems calculated for several times beginning with the observed start of the flare. The analysis is consistent with a spectral history of a flare in which the X-ray radiation becomes progressively harder as the flare advances toward maximum. The analysis indicates the existence of vertical variation in the global wind systems in the dynamo region, resulting in a reversal of current in the upper portion of this region. It suggests that the time analysis of SFE represents a new tool for examining the vertical structure of the winds in this region.
