We present three-dimensional reconstructions of coronal mass ejections (CMEs), which were obtained through polarization analysis of single-view images recorded with the use of the Large Angle and Spectrometric Coronagraph (LASCO) C2 coronagraph on board the Solar and Heliospheric Observatory (SOHO) spacecraft. Analysis of a loop-like CME shows a complex three-dimensional structure centered at 40 degrees from the plane of the sky, moving radially at 250 kilometers/second. Reconstruction of two halo CMEs suggests that these events are expanding loop arcades.
我们展示了日冕物质抛射（CME）的三维重建结果，这些重建是通过对使用太阳和日球层天文台（SOHO）航天器上的大角度光谱日冕仪（LASCO）C2日冕仪记录的单视图图像进行偏振分析获得的。对一个环状CME的分析显示，其复杂的三维结构以距天空平面40度为中心，以250公里/秒的速度径向移动。对两个晕状CME的重建表明，这些事件是正在扩展的环状拱廊结构。
