【Abstract】 The geomagnetic effects of the total solar eclipse in Mohe area and the partialeclipse, occurred on March 9, 1997 in China are analysed in this paper. The geomagnetic effects of the eclipse widely in China area are obtained, which show H component decreases obviously along latitude, showing a symmetric distribution by the center of some 33°N during the eclipse time. These results of geomagnetic effects of solar eclipse are the newest in recent years observed in the largest area in China.更多还原
