项目摘要

Charged particles in the magnetosphere are constrained to move along magnetic field fines. Thus the similarity of auroral events in opposite hemisphere can be used to investigate the linkage of the magnetospheric field lines. After the early studies of conjugate auroral events, variable displacements of the point of best conjugacy and non conjugacy activities within instrument field of view in the opposite hemisphere have been reported.Since these early work, our understanding of the important role in the generations of auroras has improved. We are now realized that the conjugecy of auroras may reflects the auroral electric fields, particle acceleration, precipitation processes, and solar windmagnetosphere interaction as well as the configurations of the geomagnetic fields. Recently. many workers are investigating the auroral conjugacy in the polar cusp and cap regions using conjugate data. Because the field lines emanating from one hemisphere at high latitude in the polar cusp/cap reg … More ion it make interaction strongly with solar wind especially in the dayside, so it is a interesting question that the field lines emanating from the high latitude region may connect to the other hemisphere or may connect to the interplanetary medium.There are still lots of unsolved problems for the conjugate study of visible auroras in the auroral zone in the close field lines. Previous works in the auroral zone were mainly concentrated with the conjugacy of auroral forms and displacements in the conjugate regions. Hence significant unsolved physical characteristics of the auroral conjugacy, such as the conjugacy of the auroral activity, movement, and deformation have been still remained.In order to study the unsolved prblems for the conjugacy of visible auroras between Syowa Station in Antarctica and 3 stations in Iceland and polar cusp/cap auroras in Arctic regions we carried out in the following observations ;April-May, 1994 : Maintenance of imaging riometer at Tjorness in Iceland.August-September, 1994 : Conjugate observation of visible auroras at Husafell in Iceland by all-sky TV cameras.Maintenance of instruments at Husafell, Tjorness and Acdey.December, 1994-January, 1995 : Polar cusp/cap visible auroral observations at 3 stations in Greenland.February-March, 1995 : Stereo observation at 2 stations in Sweden.

磁层中的带电粒子被限制在沿着磁场的细微处运动。因此，对半球极光事件的相似性可以用来研究磁层磁力线的联系。在共轭极光事件的早期研究之后，人们发现了在仪器视场内，最佳共轭和非共轭活动点在对半球的可变位移，从而加深了人们对极光发生过程中重要作用的认识。极光的共轭现象不仅反映了极光电场、粒子加速、降水过程、太阳风-磁层相互作用以及地磁场的位形。最近许多工作者正在利用共轭数据研究极尖和极帽区的极光共轭现象。因为从极尖/极帽区高纬度的一个半球发出的磁力线 ...更多信息离子与太阳风的相互作用很强，特别是在太阳的昼面，因此，从高纬地区发出的磁力线是与另一半球相连还是与行星际介质相连是一个有趣的问题，近场线极光带可见极光的共轭研究还有许多问题没有解决。以往对极光带的研究主要集中在极光形式的共轭性和共轭区的位移。为了研究南极洲Syowa站与冰岛3个站之间可见极光和北极地区极尖/极帽极光的共轭现象，我们于1994年4 - 5月进行了如下观测：1994年8月至9月：在冰岛Tjorness对成像riometer的维护：用全天空电视摄像机对冰岛Husafell的可见极光进行共轭观测，Husafell、Tjorness和Acdey仪器的维护，1994年12月至1995年1月：在格陵兰岛3个站对极尖/极帽可见极光的观测，1995年2月至3月：在瑞典的2个观测站进行立体观测。少
