新浮磁流区的观测和分析

本文利用紫金山天文台的太阳精细结构望远镜在1991年10月至1992年6月间拍摄到的标准新浮磁流区(EFR)的资料,研究了四个EFR的生长和发展。我们的观测肯定了新浮磁流区早期的一些观测结果,如EFR从光球下浮出前色球大气就已被加热,以及引起磁场位形改变导致暗条激活。我们还发现反转磁极性的EFR并不向正常方向旋转,观测到EFR中的弧形暗条系(AFS)里除了正常的流动外,还具有和经典的AFS中物质流动相异常的运动。

OBSERVATIONS AND ANALYSES OF EMERGING FLUX REGIONS

Using the Ha - filtergrams from October 1991 to June 1992 obtained with our 26 - cm solar photospheric and choromospheric telescope, we analyse the birth and growth of four typical emerging flux regions(EFRs) . The early observational results of (EFRs) are confirmed, such as EFR heating choromospheric atmosphere and activating filaments before emerging from sub-photosphere. Some new phenomena are found. An EFR with reversed polarity does not rotate to the proper orientation as usually does, that is, nearly to parallel to the equator. Finally, the observation on Ha off - band of an AFS in an EFR shows abnormal motion with classic results from Bruzek in 1969.
