AR 5395黑子运动和复杂磁场

Movement of the Umbrae and the Complicated Magnetic Configuration in AR 5395

AR 5395黑子群内存在着各部分以0～1.1°/天的不等速的平移运动和群体内三个小区域的旋转运动,群体呈现的复杂强磁场结构也在激烈地变化着。本文着重讨论了其运动演变情况。

A variety of striking movements of the umbrae and the violent changes in the magnetic field in AR 5395, one of the rare high-latitude active regions of Cycle 22, are described in this present article.
