Statistical Analysis and Configuration Classification of the Magnetic Fields of the Active Prominences on the Solar Limb During Cycle 21

本文对1979年2月至1982年8月太阳活动峰年期附近的79个活动日珥(见表5)作了形态统计分析。包括:对应活动区曾发生耀斑情况,日珥最大高度及物质运动速度,日珥经纬度分布,日珥活动级别大小,日珥对应X事件及对应黑子群磁结构等。并进行了日珥按磁场位形的分类。得到:1.环珥全部对应X事件,活动日珥较边缘耀斑对应X事件强一些。2.活动日珥物质上升高度以R⊙/10以下占多数。3.活动日珥物质运动速度多在±100km/s之间。4.活动日珥多数分布在纬度10°～20°之间,在卡林顿经度340°和110°附近出现较为集中的分布。5.前导黑子区发生活动日珥较多。6.提出日珥按磁场位形的几种分类设想。

In the present paper, the synthetically statistical analysis and configuration of classification of the magnetic fields are made for 79 Ha active prominences which were observed from January in 1979 to August in 1982 during Cycle 21. The results show: ( 1 )A11 the loop prominences and surges produce X-ray bursts, but the X-ray bursts from, the surges are more than those from the prominences, and the X-ray bursts produced from the active prominences are more intensive than those from the limb flares. ( 2 ) Most of the velocities of matter of the active prominences are between ±100km/sec. (3) The ascending height of the, matter of the active prominences is generally below R◎/10. (4 )Most active prominences are spatially distributed between 10° and 20° of the carrington heliographic latitudes, and near 340° and 110° of the carrington heligraphic longitudes and (5) The active prominences produced by the preceding sunspots are more than those produced by other sunspots. Some ideas of the dassification of the configu-ration of the magnetic fields of prominences are also presented.
