  • 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.
