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.

磁层中的带电颗粒受到限制，以沿磁场罚款移动。相对半球的极光事件的相似性可用于研究磁层磁层线的连锁。在早期研究共轭极光事件之后，已经报道了在相反半球的仪器视野内的最佳结合点和非共轭活动的可变位移。从这些早期工作中，我们对几代极光中重要作用的理解得到了改善。现在，我们已经意识到，极光的偶像可能反映了极光电场，颗粒加速度，降水过程和太阳能磁层相互作用以及地磁场的构型。最近。许多工人正在使用共轭数据调查极性尖和CAP区域中的极光结合。因为从一个半球处的高纬度/帽子盖重注的一个半球散发出的田间线……更多的离子使与太阳风的相互作用很强，尤其是在时代，因此，从高纬度地区发出的野外线可能会连接到其他半球，或者可能连接到其他媒介中的相互作用的问题，以相互访问。关闭字段线。在极光区的先前作品主要集中在共轭区域中极光形式和位移的结合。因此，仍然保持了极光性结合的显着未解决的物理特征，例如极光活动，运动和变形的结合性仍然存在。为了研究Syowa站与icelant和极地Cusp/Cap Auboras的3个站点的Syowa站点之间可见光的尚未解决的问题，以使Arctica的相互轭含量均保持不变。 ;; 1994年4月至五月：冰岛的Tjorness的成像仪表维持。1994年8月至9月：通过All-Sky TV摄像机对冰岛的Husafell的可见光观察。格陵兰。1995年3月：瑞典2个站点的立体观察。较少的
