太阳宁静区色球磁场观测

利用中国科学院北京天文台怀柔太阳磁场望远镜，对日面中心宁静区光球和色球磁场进行了长时间的积分观测。通过对光球，色球以及色球不同层次的长时间积分的同现，网络磁元从光球到色球扩展不大，并且部分内网络磁元升到了色球。这些结果对描述太阳磁场的两大模拟提出了挑战。

CHROMOSPHERIC MAGNETIC FIELDS OBSERVATION FOR QUIET-SUN REGIONS

Using the solar magnetic field telescope in Huairou Station of Beijing Astronomical Observatory, the solar photospheric and chromospheric magnetic fields forquiet-Sun regions have been observed for the first time. By a study of deep magnetograms of solar photosphere, chromosphere and different levels of chromosphere,it is found that the network magnetic tubes do not diverge a lot from the solarphotosphere to the chromosphere, which is contrary to the popular canopy model'spredication. It is also found that the intranetwork magnetic tubes have reached thesolar chromosphere, which is also contrary to the dynamo model's Predication thatthe intranetwork magnetic tubes will not reach high atmosphere. This observationof solar chromospheric magnetic fields for quiet-Sun regions have challenged twopopular models of solar atmosphere.
