太阳宁静区磁元的空间结构

SPATIAL STRUCTURE OF SMALL SCALE MAGNETIC STRUCTURES IN QUIET SUN REGIONS

利用怀柔太阳磁场望远镜，我们对太阳宁静区光球和色球磁场进行了观测。日面中心到边缘的观测表明，太阳宁静区中的小尺度磁结构在从光球到色球的扩展过程中变化不大。日面边缘的观测表明，小尺度磁结构的水平分量在光球和色球都不大。对极区和赤道边缘纵向磁场的比较发现。

Photospheric (FeⅠλ5324.19A) and chromospheric (H β) magnetic fields of small scale magnetic structures have been simultaneously observed, using the vector video magnetograph at Huairou Solar Observing Station of Beijing Astronomical Observatory. Center to limb observations show that the magnetic structures of small scale magnetic structures have not changed much when they extend from the solar photosphere to the chromosphere. Solar limb observations tell us that there are not much horizontal components of small scale magnetic structures both in the solar pohotosphere and chromosphere. Comparisons between the pole observations and equator limb observations indicate that the magnetic configuration of small scale magnetic structures near the solar poles may be different from that of small scale magnetic structures along the solar equator.
