1.CHANGE CHARACTERISTICS OF MAGNETIC STORM IN ANTARCTIC ZHONGSHAN STATION AND BEIJING MING TOMBS MAGNETIC OBSERVATORY CENTER OF CHINA ON MARCH 24,1991
2.This is the second report on the topic whether seismomagnetic signals exist in the Sq variations of three magnetic components before great earthquakes. A great earthquake of M S7 1 occurred on October 19, 1996 near the Kanoya magnetic observatory in Miyazaki, Kyushu, Japan. The distance between the epicenter and the Kanoya observatory is about 90 km.
4.Based on the data of the vector magnetic fields measured at MSFC/NASA and the pictures of a sunspot group photographed at Yunnan Observatory in early February 1986, the authors detail the photospheric morphology and evolution of the active region AR4711. The main results are:i) There is a close morphological correlation between penumbral filaments (PF) and the transversal magnetic fields (TMF) nearly everywhere in the region.
5.Complex type III-moving IV solar radio burst on Sep. 23, 1998 observed with radio spectrometers (1 - 2 GHz and 2.6 - 3.8 GHz) at Beijing Astronomical Observatory (BAO) is analyzed preliminarily, combining with the data obtained from the SSRT (5.7 GHz ) in Russia and radio spectrometer in Germany. These study fields of electron acceleration and magnetic structures in the corona are expanded.
